Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

												This commit frees list ui items from their dependencies to Panel, and hence from all the limitations this implied (mostly, the "only one list per panel" one).
It introduces a new (py-extendable and registrable) RNA type, UIList (roughly similar to Panel one), which currently contains only "standard" list's scroll pos and size (but may be expended to include e.g. some filtering data, etc.). This now makes lists completely independent from Panels!
This UIList has a draw_item callback which allows to customize items' drawing from python, that all addons can now use. Incidentally, this also greatly simplifies the C code of this widget, as we do not code any "special case" here anymore!
To make all this work, other changes were also necessary:
* Now all buttons (uiBut struct) have a 'custom_data' void pointer, used currently to store the uiList struct associated with a given uiLayoutListBox.
* DynamicPaintSurface now exposes a new bool, use_color_preview (readonly), saying whether that surface has some 3D view preview data or not.
* UILayout class has now four new (static) functions, to get the actual icon of any RNA object (important e.g. with materials or textures), and to get an enum item's UI name, description and icon.
* UILayout's label() func now takes an optional 'icon_value' integer parameter, which if not zero will override the 'icon' one (mandatory to use "custom" icons as generated for material/texture/... previews).
  Note: not sure whether we should add that one to all UILayout's prop funcs?
Note: will update addons using template list asap.

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.

* The header in the time space currently has some buttons to test the UI code.

												Drag and drop 2.5 integration! Finally, slashdot regulars can use
Blender too now! :)
** Drag works as follows:
- drag-able items are defined by the standard interface ui toolkit
- each button can get this feature, via uiButSetDragXXX(but, ...).
  There are calls to define drag-able images, ID blocks, RNA paths, 
  file paths, and so on. By default you drag an icon, exceptionally 
  an ImBuf
- Drag items are registered centrally in the WM, it allows more drag 
  items simultaneous too, but not implemented
** Drop works as follows:
- On mouse release, and if drag items exist in the WM, it converts 
  the mouse event to an EVT_DROP type. This event then gets the full 
  drag info as customdata
- drop regions are defined with WM_dropbox_add(), similar to keymaps 
  you can make a "drop map" this way, which become 'drop map handlers' 
  in the queues.
- next to that the UI kit handles some common button types (like 
  accepting ID or names) to be catching a drop event too.
- Every "drop box" has two callbacks:
  - poll() = check if the event drag data is relevant for this box
  - copy() = fill in custom properties in the dropbox to initialize 
    an operator
- The dropbox handler then calls its standard Operator with its 
  dropbox properties.
** Currently implemented
Drag items:
- ID icons in browse buttons
- ID icons in context menu of properties region
- ID icons in outliner and rna viewer
- FileBrowser icons
- FileBrowser preview images
Drag-able icons are subtly visualized by making them brighter a bit 
on mouse-over. In case the icon is a button or UI element too (most 
cases), the drag-able feature will make the item react to 
mouse-release instead of mouse-press. 
Drop options:
- UI buttons: ID and text buttons (paste name)
- View3d: Object ID drop copies object
- View3d: Material ID drop assigns to object under cursor
- View3d: Image ID drop assigns to object UV texture under cursor
- Sequencer: Path drop will add either Image or Movie strip
- Image window: Path drop will open image
** Drag and drop Notes:
- Dropping into another Blender window (from same application) works 
too. I've added code that passes on mousemoves and clicks to other 
windows, without activating them though. This does make using multi-window
Blender a bit friendler.
- Dropping a file path to an image, is not the same as dropping an 
Image ID... keep this in mind. Sequencer for example wants paths to 
be dropped,  textures in 3d window wants an Image ID.
- Although drop boxes could be defined via Python, I suggest they're 
part of the UI and editor design (= how we want an editor to work), and 
not default offered configurable like keymaps. 
- At the moment only one item can be dragged at a time. This is for 
several reasons.... For one, Blender doesn't have a well defined 
uniform way to define "what is selected" (files, outliner items, etc). 
Secondly there's potential conflicts on what todo when you drop mixed 
drag sets on spots. All undefined stuff... nice for later.
- Example to bypass the above: a collection of images that form a strip, 
should be represented in filewindow as a single sequence anyway. 
This then will fit well and gets handled neatly by design.
- Another option to check is to allow multiple options per drop... it 
could show the operator as a sort of menu, allowing arrow or scrollwheel 
to choose. For time being I'd prefer to try to design a singular drop 
though, just offer only one drop action per data type on given spots.
- What does work already, but a tad slow, is to use a function that 
detects an object (type) under cursor, so a drag item's option can be 
further refined (like drop object on object = parent). (disabled)
** More notes
- Added saving for Region layouts (like split points for toolbar)
- Label buttons now handle mouse over
- File list: added full path entry for drop feature.
- Filesel bugfix: wm_operator_exec() got called there and fully handled, 
while WM event code tried same. Added new OPERATOR_HANDLED flag for this. 
Maybe python needs it too?
- Cocoa: added window move event, so multi-win setups work OK (didnt save).
- Interface_handlers.c: removed win->active
- Severe area copy bug: area handlers were not set to NULL
- Filesel bugfix: next/prev folder list was not copied on area copies
** Leftover todos
- Cocoa windows seem to hang on cases still... needs check
- Cocoa 'draw overlap' swap doesn't work
- Cocoa window loses focus permanently on using Spotlight
  (for these reasons, makefile building has Carbon as default atm)
- ListView templates in UI cannot become dragged yet, needs review... 
it consists of two overlapping UI elements, preventing handling icon clicks.
- There's already Ghost library code to handle dropping from OS 
into Blender window. I've noticed this code is unfinished for Macs, but 
seems to be complete for Windows. Needs test... currently, an external 
drop event will print in console when succesfully delivered to Blender's WM.

												UI: Layout Engine
* Buttons are now created first, and after that the layout is computed.
  This means the layout engine now works at button level, and makes it
  easier to write templates. Otherwise you had to store all info and
  create the buttons later.
* Added interface_templates.c as a separate file to put templates in.
  These can contain regular buttons, and can be put in a Free layout,
  which means you can specify manual coordinates, but still get nested
  correct inside other layouts.
* API was changed to allow better nesting. Previously items were added
  in the last added layout specifier, i.e. one level up in the layout
  hierarchy. This doesn't work well in always, so now when creating things
  like rows or columns it always returns a layout which you have to add
  the items in. All py scripts were updated to follow this.
* Computing the layout now goes in two passes, first estimating the
  required width/height of all nested layouts, and then in the second
  pass using the results of that to decide on the actual locations.
* Enum and array buttons now follow the direction of the layout, i.e.
  they are vertical or horizontal depending if they are in a column or row.
* Color properties now get a color picker, and only get the additional
  RGB sliders with Expand=True.
* File/directory string properties now get a button next to them for
  opening the file browse, though this is not implemented yet.
* Layout items can now be aligned, set align=True when creating a column,
  row, etc.
* Buttons now get a minimum width of one icon (avoids squashing icon
  buttons).
* Moved some more space variables into Style.

UI: don't use operators anymore for handling user interface events, but rather
a special UI handler which makes the code clearer. This UI handler is attached
to the region along with other handlers, and also gets a callback when all
handlers for the region are removed to ensure things are properly cleaned up.
This should fix XXX's in the UI code related to events and context switching.
Most of the changes are in interface_handlers.c, which was renamed from
interface_ops.c, to convert operators to the UI handler. UI code notes:
* uiBeginBlock/uiEndBlock/uiFreeBlocks now takes a context argument, this is
  required to properly cancel things like timers or tooltips when the region
  gets removed.
* UI_add_region_handlers will add the region level UI handlers, to be used
  when adding keymap handlers etc. This replaces the UI keymap.
* When the UI code starts a modal interaction (number sliding, text editing,
  opening a menu, ..), it will add an UI handler at the window level which
  will block events.
Windowmanager changes:
* Added an UI handler next to the existing keymap and operator modal handlers.
  It has an event handling and remove callback, and like operator modal handlers
  will remember the area and region if it is registered at the window level.
* Removed the MESSAGE event.
* Operator cancel and UI handler remove callbacks now get the
  window/area/region restored in the context, like the operator modal and UI
  handler event callbacks.
* Regions now receive MOUSEMOVE events for the mouse going outside of the
  region. This was already happening for areas, but UI buttons are at the region
  level so we need it there.
Issues:
* Tooltips and menus stay open when switching to another window, and button
  highlight doesn't work without moving the mouse first when Blender starts up.
  I tried using some events like Q_FIRSTTIME, WINTHAW, but those don't seem to
  arrive..
* Timeline header buttons seem to be moving one pixel or so sometimes when
  interacting with them.
* Seems not due to this commit, but UI and keymap handlers are leaking. It
  seems that handlers are being added to regions in all screens, also in regions
  of areas that are not visible, but these handlers are not removed. Probably
  there should only be handlers in visible regions?

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.

* The header in the time space currently has some buttons to test the UI code.

												2.5: ID datablock button back, previously known as std_libbuttons. The
way this worked in 2.4x wasn't really clean, with events going all over
the place and using dubious variables such as G.but->lockpoin or
G.sima->menunr. It works as follows now, for example:
xco= uiDefIDPoinButs(block, CTX_data_main(C), NULL, (ID**)&sima->image, ID_IM, &sima->pin, xco, yco,
	sima_idpoin_handle, UI_ID_BROWSE|UI_ID_RENAME|UI_ID_ADD_NEW|UI_ID_OPEN|UI_ID_DELETE|UI_ID_ALONE|UI_ID_PIN);
The last two parameters are a callback function, and a list of events
or functionalities that are supported. The callback function will then
get the ID pointer + event to handle.

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.

  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.

  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.

  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.

* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.

  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code

* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special

												Drag and drop 2.5 integration! Finally, slashdot regulars can use
Blender too now! :)
** Drag works as follows:
- drag-able items are defined by the standard interface ui toolkit
- each button can get this feature, via uiButSetDragXXX(but, ...).
  There are calls to define drag-able images, ID blocks, RNA paths, 
  file paths, and so on. By default you drag an icon, exceptionally 
  an ImBuf
- Drag items are registered centrally in the WM, it allows more drag 
  items simultaneous too, but not implemented
** Drop works as follows:
- On mouse release, and if drag items exist in the WM, it converts 
  the mouse event to an EVT_DROP type. This event then gets the full 
  drag info as customdata
- drop regions are defined with WM_dropbox_add(), similar to keymaps 
  you can make a "drop map" this way, which become 'drop map handlers' 
  in the queues.
- next to that the UI kit handles some common button types (like 
  accepting ID or names) to be catching a drop event too.
- Every "drop box" has two callbacks:
  - poll() = check if the event drag data is relevant for this box
  - copy() = fill in custom properties in the dropbox to initialize 
    an operator
- The dropbox handler then calls its standard Operator with its 
  dropbox properties.
** Currently implemented
Drag items:
- ID icons in browse buttons
- ID icons in context menu of properties region
- ID icons in outliner and rna viewer
- FileBrowser icons
- FileBrowser preview images
Drag-able icons are subtly visualized by making them brighter a bit 
on mouse-over. In case the icon is a button or UI element too (most 
cases), the drag-able feature will make the item react to 
mouse-release instead of mouse-press. 
Drop options:
- UI buttons: ID and text buttons (paste name)
- View3d: Object ID drop copies object
- View3d: Material ID drop assigns to object under cursor
- View3d: Image ID drop assigns to object UV texture under cursor
- Sequencer: Path drop will add either Image or Movie strip
- Image window: Path drop will open image
** Drag and drop Notes:
- Dropping into another Blender window (from same application) works 
too. I've added code that passes on mousemoves and clicks to other 
windows, without activating them though. This does make using multi-window
Blender a bit friendler.
- Dropping a file path to an image, is not the same as dropping an 
Image ID... keep this in mind. Sequencer for example wants paths to 
be dropped,  textures in 3d window wants an Image ID.
- Although drop boxes could be defined via Python, I suggest they're 
part of the UI and editor design (= how we want an editor to work), and 
not default offered configurable like keymaps. 
- At the moment only one item can be dragged at a time. This is for 
several reasons.... For one, Blender doesn't have a well defined 
uniform way to define "what is selected" (files, outliner items, etc). 
Secondly there's potential conflicts on what todo when you drop mixed 
drag sets on spots. All undefined stuff... nice for later.
- Example to bypass the above: a collection of images that form a strip, 
should be represented in filewindow as a single sequence anyway. 
This then will fit well and gets handled neatly by design.
- Another option to check is to allow multiple options per drop... it 
could show the operator as a sort of menu, allowing arrow or scrollwheel 
to choose. For time being I'd prefer to try to design a singular drop 
though, just offer only one drop action per data type on given spots.
- What does work already, but a tad slow, is to use a function that 
detects an object (type) under cursor, so a drag item's option can be 
further refined (like drop object on object = parent). (disabled)
** More notes
- Added saving for Region layouts (like split points for toolbar)
- Label buttons now handle mouse over
- File list: added full path entry for drop feature.
- Filesel bugfix: wm_operator_exec() got called there and fully handled, 
while WM event code tried same. Added new OPERATOR_HANDLED flag for this. 
Maybe python needs it too?
- Cocoa: added window move event, so multi-win setups work OK (didnt save).
- Interface_handlers.c: removed win->active
- Severe area copy bug: area handlers were not set to NULL
- Filesel bugfix: next/prev folder list was not copied on area copies
** Leftover todos
- Cocoa windows seem to hang on cases still... needs check
- Cocoa 'draw overlap' swap doesn't work
- Cocoa window loses focus permanently on using Spotlight
  (for these reasons, makefile building has Carbon as default atm)
- ListView templates in UI cannot become dragged yet, needs review... 
it consists of two overlapping UI elements, preventing handling icon clicks.
- There's already Ghost library code to handle dropping from OS 
into Blender window. I've noticed this code is unfinished for Macs, but 
seems to be complete for Windows. Needs test... currently, an external 
drop event will print in console when succesfully delivered to Blender's WM.

- Sequencer: Path drop will add either Image or Movie strip
- Image window: Path drop will open image
** Drag and drop Notes:
- Dropping into another Blender window (from same application) works 
too. I've added code that passes on mousemoves and clicks to other 
windows, without activating them though. This does make using multi-window
Blender a bit friendler.
- Dropping a file path to an image, is not the same as dropping an 
Image ID... keep this in mind. Sequencer for example wants paths to 
be dropped,  textures in 3d window wants an Image ID.
- Although drop boxes could be defined via Python, I suggest they're 
part of the UI and editor design (= how we want an editor to work), and 
not default offered configurable like keymaps. 
- At the moment only one item can be dragged at a time. This is for 
several reasons.... For one, Blender doesn't have a well defined 
uniform way to define "what is selected" (files, outliner items, etc). 
Secondly there's potential conflicts on what todo when you drop mixed 
drag sets on spots. All undefined stuff... nice for later.
- Example to bypass the above: a collection of images that form a strip, 
should be represented in filewindow as a single sequence anyway. 
This then will fit well and gets handled neatly by design.
- Another option to check is to allow multiple options per drop... it 
could show the operator as a sort of menu, allowing arrow or scrollwheel 
to choose. For time being I'd prefer to try to design a singular drop 
though, just offer only one drop action per data type on given spots.
- What does work already, but a tad slow, is to use a function that 
detects an object (type) under cursor, so a drag item's option can be 
further refined (like drop object on object = parent). (disabled)
** More notes
- Added saving for Region layouts (like split points for toolbar)
- Label buttons now handle mouse over
- File list: added full path entry for drop feature.
- Filesel bugfix: wm_operator_exec() got called there and fully handled, 
while WM event code tried same. Added new OPERATOR_HANDLED flag for this. 
Maybe python needs it too?
- Cocoa: added window move event, so multi-win setups work OK (didnt save).
- Interface_handlers.c: removed win->active
- Severe area copy bug: area handlers were not set to NULL
- Filesel bugfix: next/prev folder list was not copied on area copies
** Leftover todos
- Cocoa windows seem to hang on cases still... needs check
- Cocoa 'draw overlap' swap doesn't work
- Cocoa window loses focus permanently on using Spotlight
  (for these reasons, makefile building has Carbon as default atm)
- ListView templates in UI cannot become dragged yet, needs review... 
it consists of two overlapping UI elements, preventing handling icon clicks.
- There's already Ghost library code to handle dropping from OS 
into Blender window. I've noticed this code is unfinished for Macs, but 
seems to be complete for Windows. Needs test... currently, an external 
drop event will print in console when succesfully delivered to Blender's WM.

												Drag and drop 2.5 integration! Finally, slashdot regulars can use
Blender too now! :)
** Drag works as follows:
- drag-able items are defined by the standard interface ui toolkit
- each button can get this feature, via uiButSetDragXXX(but, ...).
  There are calls to define drag-able images, ID blocks, RNA paths, 
  file paths, and so on. By default you drag an icon, exceptionally 
  an ImBuf
- Drag items are registered centrally in the WM, it allows more drag 
  items simultaneous too, but not implemented
** Drop works as follows:
- On mouse release, and if drag items exist in the WM, it converts 
  the mouse event to an EVT_DROP type. This event then gets the full 
  drag info as customdata
- drop regions are defined with WM_dropbox_add(), similar to keymaps 
  you can make a "drop map" this way, which become 'drop map handlers' 
  in the queues.
- next to that the UI kit handles some common button types (like 
  accepting ID or names) to be catching a drop event too.
- Every "drop box" has two callbacks:
  - poll() = check if the event drag data is relevant for this box
  - copy() = fill in custom properties in the dropbox to initialize 
    an operator
- The dropbox handler then calls its standard Operator with its 
  dropbox properties.
** Currently implemented
Drag items:
- ID icons in browse buttons
- ID icons in context menu of properties region
- ID icons in outliner and rna viewer
- FileBrowser icons
- FileBrowser preview images
Drag-able icons are subtly visualized by making them brighter a bit 
on mouse-over. In case the icon is a button or UI element too (most 
cases), the drag-able feature will make the item react to 
mouse-release instead of mouse-press. 
Drop options:
- UI buttons: ID and text buttons (paste name)
- View3d: Object ID drop copies object
- View3d: Material ID drop assigns to object under cursor
- View3d: Image ID drop assigns to object UV texture under cursor
- Sequencer: Path drop will add either Image or Movie strip
- Image window: Path drop will open image

												Drag and drop 2.5 integration! Finally, slashdot regulars can use
Blender too now! :)
** Drag works as follows:
- drag-able items are defined by the standard interface ui toolkit
- each button can get this feature, via uiButSetDragXXX(but, ...).
  There are calls to define drag-able images, ID blocks, RNA paths, 
  file paths, and so on. By default you drag an icon, exceptionally 
  an ImBuf
- Drag items are registered centrally in the WM, it allows more drag 
  items simultaneous too, but not implemented
** Drop works as follows:
- On mouse release, and if drag items exist in the WM, it converts 
  the mouse event to an EVT_DROP type. This event then gets the full 
  drag info as customdata
- drop regions are defined with WM_dropbox_add(), similar to keymaps 
  you can make a "drop map" this way, which become 'drop map handlers' 
  in the queues.
- next to that the UI kit handles some common button types (like 
  accepting ID or names) to be catching a drop event too.
- Every "drop box" has two callbacks:
  - poll() = check if the event drag data is relevant for this box
  - copy() = fill in custom properties in the dropbox to initialize 
    an operator
- The dropbox handler then calls its standard Operator with its 
  dropbox properties.
** Currently implemented
Drag items:
- ID icons in browse buttons
- ID icons in context menu of properties region
- ID icons in outliner and rna viewer
- FileBrowser icons
- FileBrowser preview images
Drag-able icons are subtly visualized by making them brighter a bit 
on mouse-over. In case the icon is a button or UI element too (most 
cases), the drag-able feature will make the item react to 
mouse-release instead of mouse-press. 
Drop options:
- UI buttons: ID and text buttons (paste name)
- View3d: Object ID drop copies object
- View3d: Material ID drop assigns to object under cursor
- View3d: Image ID drop assigns to object UV texture under cursor
- Sequencer: Path drop will add either Image or Movie strip
- Image window: Path drop will open image
** Drag and drop Notes:
- Dropping into another Blender window (from same application) works 
too. I've added code that passes on mousemoves and clicks to other 
windows, without activating them though. This does make using multi-window
Blender a bit friendler.
- Dropping a file path to an image, is not the same as dropping an 
Image ID... keep this in mind. Sequencer for example wants paths to 
be dropped,  textures in 3d window wants an Image ID.
- Although drop boxes could be defined via Python, I suggest they're 
part of the UI and editor design (= how we want an editor to work), and 
not default offered configurable like keymaps. 
- At the moment only one item can be dragged at a time. This is for 
several reasons.... For one, Blender doesn't have a well defined 
uniform way to define "what is selected" (files, outliner items, etc). 
Secondly there's potential conflicts on what todo when you drop mixed 
drag sets on spots. All undefined stuff... nice for later.
- Example to bypass the above: a collection of images that form a strip, 
should be represented in filewindow as a single sequence anyway. 
This then will fit well and gets handled neatly by design.
- Another option to check is to allow multiple options per drop... it 
could show the operator as a sort of menu, allowing arrow or scrollwheel 
to choose. For time being I'd prefer to try to design a singular drop 
though, just offer only one drop action per data type on given spots.
- What does work already, but a tad slow, is to use a function that 
detects an object (type) under cursor, so a drag item's option can be 
further refined (like drop object on object = parent). (disabled)
** More notes
- Added saving for Region layouts (like split points for toolbar)
- Label buttons now handle mouse over
- File list: added full path entry for drop feature.
- Filesel bugfix: wm_operator_exec() got called there and fully handled, 
while WM event code tried same. Added new OPERATOR_HANDLED flag for this. 
Maybe python needs it too?
- Cocoa: added window move event, so multi-win setups work OK (didnt save).
- Interface_handlers.c: removed win->active
- Severe area copy bug: area handlers were not set to NULL
- Filesel bugfix: next/prev folder list was not copied on area copies
** Leftover todos
- Cocoa windows seem to hang on cases still... needs check
- Cocoa 'draw overlap' swap doesn't work
- Cocoa window loses focus permanently on using Spotlight
  (for these reasons, makefile building has Carbon as default atm)
- ListView templates in UI cannot become dragged yet, needs review... 
it consists of two overlapping UI elements, preventing handling icon clicks.
- There's already Ghost library code to handle dropping from OS 
into Blender window. I've noticed this code is unfinished for Macs, but 
seems to be complete for Windows. Needs test... currently, an external 
drop event will print in console when succesfully delivered to Blender's WM.

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.

* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.

* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.

  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code

This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions?

												Drag and drop 2.5 integration! Finally, slashdot regulars can use
Blender too now! :)
** Drag works as follows:
- drag-able items are defined by the standard interface ui toolkit
- each button can get this feature, via uiButSetDragXXX(but, ...).
  There are calls to define drag-able images, ID blocks, RNA paths, 
  file paths, and so on. By default you drag an icon, exceptionally 
  an ImBuf
- Drag items are registered centrally in the WM, it allows more drag 
  items simultaneous too, but not implemented
** Drop works as follows:
- On mouse release, and if drag items exist in the WM, it converts 
  the mouse event to an EVT_DROP type. This event then gets the full 
  drag info as customdata
- drop regions are defined with WM_dropbox_add(), similar to keymaps 
  you can make a "drop map" this way, which become 'drop map handlers' 
  in the queues.
- next to that the UI kit handles some common button types (like 
  accepting ID or names) to be catching a drop event too.
- Every "drop box" has two callbacks:
  - poll() = check if the event drag data is relevant for this box
  - copy() = fill in custom properties in the dropbox to initialize 
    an operator
- The dropbox handler then calls its standard Operator with its 
  dropbox properties.
** Currently implemented
Drag items:
- ID icons in browse buttons
- ID icons in context menu of properties region
- ID icons in outliner and rna viewer
- FileBrowser icons
- FileBrowser preview images
Drag-able icons are subtly visualized by making them brighter a bit 
on mouse-over. In case the icon is a button or UI element too (most 
cases), the drag-able feature will make the item react to 
mouse-release instead of mouse-press. 
Drop options:
- UI buttons: ID and text buttons (paste name)
- View3d: Object ID drop copies object
- View3d: Material ID drop assigns to object under cursor
- View3d: Image ID drop assigns to object UV texture under cursor
- Sequencer: Path drop will add either Image or Movie strip
- Image window: Path drop will open image
** Drag and drop Notes:
- Dropping into another Blender window (from same application) works 
too. I've added code that passes on mousemoves and clicks to other 
windows, without activating them though. This does make using multi-window
Blender a bit friendler.
- Dropping a file path to an image, is not the same as dropping an 
Image ID... keep this in mind. Sequencer for example wants paths to 
be dropped,  textures in 3d window wants an Image ID.
- Although drop boxes could be defined via Python, I suggest they're 
part of the UI and editor design (= how we want an editor to work), and 
not default offered configurable like keymaps. 
- At the moment only one item can be dragged at a time. This is for 
several reasons.... For one, Blender doesn't have a well defined 
uniform way to define "what is selected" (files, outliner items, etc). 
Secondly there's potential conflicts on what todo when you drop mixed 
drag sets on spots. All undefined stuff... nice for later.
- Example to bypass the above: a collection of images that form a strip, 
should be represented in filewindow as a single sequence anyway. 
This then will fit well and gets handled neatly by design.
- Another option to check is to allow multiple options per drop... it 
could show the operator as a sort of menu, allowing arrow or scrollwheel 
to choose. For time being I'd prefer to try to design a singular drop 
though, just offer only one drop action per data type on given spots.
- What does work already, but a tad slow, is to use a function that 
detects an object (type) under cursor, so a drag item's option can be 
further refined (like drop object on object = parent). (disabled)
** More notes
- Added saving for Region layouts (like split points for toolbar)
- Label buttons now handle mouse over
- File list: added full path entry for drop feature.
- Filesel bugfix: wm_operator_exec() got called there and fully handled, 
while WM event code tried same. Added new OPERATOR_HANDLED flag for this. 
Maybe python needs it too?
- Cocoa: added window move event, so multi-win setups work OK (didnt save).
- Interface_handlers.c: removed win->active
- Severe area copy bug: area handlers were not set to NULL
- Filesel bugfix: next/prev folder list was not copied on area copies
** Leftover todos
- Cocoa windows seem to hang on cases still... needs check
- Cocoa 'draw overlap' swap doesn't work
- Cocoa window loses focus permanently on using Spotlight
  (for these reasons, makefile building has Carbon as default atm)
- ListView templates in UI cannot become dragged yet, needs review... 
it consists of two overlapping UI elements, preventing handling icon clicks.
- There's already Ghost library code to handle dropping from OS 
into Blender window. I've noticed this code is unfinished for Macs, but 
seems to be complete for Windows. Needs test... currently, an external 
drop event will print in console when succesfully delivered to Blender's WM.

while WM event code tried same. Added new OPERATOR_HANDLED flag for this. 
Maybe python needs it too?
- Cocoa: added window move event, so multi-win setups work OK (didnt save).
- Interface_handlers.c: removed win->active
- Severe area copy bug: area handlers were not set to NULL
- Filesel bugfix: next/prev folder list was not copied on area copies
** Leftover todos
- Cocoa windows seem to hang on cases still... needs check
- Cocoa 'draw overlap' swap doesn't work
- Cocoa window loses focus permanently on using Spotlight
  (for these reasons, makefile building has Carbon as default atm)
- ListView templates in UI cannot become dragged yet, needs review... 
it consists of two overlapping UI elements, preventing handling icon clicks.
- There's already Ghost library code to handle dropping from OS 
into Blender window. I've noticed this code is unfinished for Macs, but 
seems to be complete for Windows. Needs test... currently, an external 
drop event will print in console when succesfully delivered to Blender's WM.

												Drag and drop 2.5 integration! Finally, slashdot regulars can use
Blender too now! :)
** Drag works as follows:
- drag-able items are defined by the standard interface ui toolkit
- each button can get this feature, via uiButSetDragXXX(but, ...).
  There are calls to define drag-able images, ID blocks, RNA paths, 
  file paths, and so on. By default you drag an icon, exceptionally 
  an ImBuf
- Drag items are registered centrally in the WM, it allows more drag 
  items simultaneous too, but not implemented
** Drop works as follows:
- On mouse release, and if drag items exist in the WM, it converts 
  the mouse event to an EVT_DROP type. This event then gets the full 
  drag info as customdata
- drop regions are defined with WM_dropbox_add(), similar to keymaps 
  you can make a "drop map" this way, which become 'drop map handlers' 
  in the queues.
- next to that the UI kit handles some common button types (like 
  accepting ID or names) to be catching a drop event too.
- Every "drop box" has two callbacks:
  - poll() = check if the event drag data is relevant for this box
  - copy() = fill in custom properties in the dropbox to initialize 
    an operator
- The dropbox handler then calls its standard Operator with its 
  dropbox properties.
** Currently implemented
Drag items:
- ID icons in browse buttons
- ID icons in context menu of properties region
- ID icons in outliner and rna viewer
- FileBrowser icons
- FileBrowser preview images
Drag-able icons are subtly visualized by making them brighter a bit 
on mouse-over. In case the icon is a button or UI element too (most 
cases), the drag-able feature will make the item react to 
mouse-release instead of mouse-press. 
Drop options:
- UI buttons: ID and text buttons (paste name)
- View3d: Object ID drop copies object
- View3d: Material ID drop assigns to object under cursor
- View3d: Image ID drop assigns to object UV texture under cursor
- Sequencer: Path drop will add either Image or Movie strip
- Image window: Path drop will open image
** Drag and drop Notes:
- Dropping into another Blender window (from same application) works 
too. I've added code that passes on mousemoves and clicks to other 
windows, without activating them though. This does make using multi-window
Blender a bit friendler.
- Dropping a file path to an image, is not the same as dropping an 
Image ID... keep this in mind. Sequencer for example wants paths to 
be dropped,  textures in 3d window wants an Image ID.
- Although drop boxes could be defined via Python, I suggest they're 
part of the UI and editor design (= how we want an editor to work), and 
not default offered configurable like keymaps. 
- At the moment only one item can be dragged at a time. This is for 
several reasons.... For one, Blender doesn't have a well defined 
uniform way to define "what is selected" (files, outliner items, etc). 
Secondly there's potential conflicts on what todo when you drop mixed 
drag sets on spots. All undefined stuff... nice for later.
- Example to bypass the above: a collection of images that form a strip, 
should be represented in filewindow as a single sequence anyway. 
This then will fit well and gets handled neatly by design.
- Another option to check is to allow multiple options per drop... it 
could show the operator as a sort of menu, allowing arrow or scrollwheel 
to choose. For time being I'd prefer to try to design a singular drop 
though, just offer only one drop action per data type on given spots.
- What does work already, but a tad slow, is to use a function that 
detects an object (type) under cursor, so a drag item's option can be 
further refined (like drop object on object = parent). (disabled)
** More notes
- Added saving for Region layouts (like split points for toolbar)
- Label buttons now handle mouse over
- File list: added full path entry for drop feature.
- Filesel bugfix: wm_operator_exec() got called there and fully handled,

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

UI: don't use operators anymore for handling user interface events, but rather
a special UI handler which makes the code clearer. This UI handler is attached
to the region along with other handlers, and also gets a callback when all
handlers for the region are removed to ensure things are properly cleaned up.
This should fix XXX's in the UI code related to events and context switching.
Most of the changes are in interface_handlers.c, which was renamed from
interface_ops.c, to convert operators to the UI handler. UI code notes:
* uiBeginBlock/uiEndBlock/uiFreeBlocks now takes a context argument, this is
  required to properly cancel things like timers or tooltips when the region
  gets removed.
* UI_add_region_handlers will add the region level UI handlers, to be used
  when adding keymap handlers etc. This replaces the UI keymap.
* When the UI code starts a modal interaction (number sliding, text editing,
  opening a menu, ..), it will add an UI handler at the window level which
  will block events.
Windowmanager changes:
* Added an UI handler next to the existing keymap and operator modal handlers.
  It has an event handling and remove callback, and like operator modal handlers
  will remember the area and region if it is registered at the window level.
* Removed the MESSAGE event.
* Operator cancel and UI handler remove callbacks now get the
  window/area/region restored in the context, like the operator modal and UI
  handler event callbacks.
* Regions now receive MOUSEMOVE events for the mouse going outside of the
  region. This was already happening for areas, but UI buttons are at the region
  level so we need it there.
Issues:
* Tooltips and menus stay open when switching to another window, and button
  highlight doesn't work without moving the mouse first when Blender starts up.
  I tried using some events like Q_FIRSTTIME, WINTHAW, but those don't seem to
  arrive..
* Timeline header buttons seem to be moving one pixel or so sometimes when
  interacting with them.
* Seems not due to this commit, but UI and keymap handlers are leaking. It
  seems that handlers are being added to regions in all screens, also in regions
  of areas that are not visible, but these handlers are not removed. Probably
  there should only be handlers in visible regions?

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated

  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,

												2.5: Text Editor back.
There was very little structure in this code, using many globals
and duplicated code. Now it should be better structured. Most
things should work, the main parts that are not back yet are the
python plugins and markers. Notes:
* Blenfont is used for drawing the text, nicely anti-aliased.
* A monospace truetype font was added, since that is needed for
  the text editor. It's Bitstream Vera Sans Mono. This is the
  default gnome terminal font, but it doesn't fit entirely well
  with the other font I think, can be changed easily of course.
* Clipboard copy/cut/paste now always uses the system clipboard,
  the code for the own cut buffer was removed.
* The interface buttons should support copy/cut/paste again now
  as well.
* WM_clipboard_text_get/WM_clipboard_text_set were added to the
  windowmanager code.
* Find panel is now a kind of second header, instead of a panel.
  This needs especially a way to start editing the text field
  immediately on open still.
* Operators are independent of the actual space when possible,
  was a bit of puzzling but got it solved nice with notifiers,
  and some lazy init for syntax highlight in the drawing code.
* RNA was created for the text editor space and used for buttons.
* Operators:
    * New, Open, Reload, Save, Save As, Make Internal
    * Run Script, Refresh Pyconstraints
    * Copy, Cut, Paste
    * Convert Whitespace, Uncomment, Comment, Indent, Unindent
    * Line Break, Insert
    * Next Marker, Previous Marker, Clear All Markers, Mark All
    * Select Line, Select All
    * Jump, Move, Move Select, Delete, Toggle Overwrite
	* Scroll, Scroll Bar, Set Cursor, Line Number
    * Find and Replace, Find, Replace, Find Set Selected,
	  Replace Set Selected
    * To 3D Object
    * Resolve Conflict

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

												2.5: Text Editor back.
There was very little structure in this code, using many globals
and duplicated code. Now it should be better structured. Most
things should work, the main parts that are not back yet are the
python plugins and markers. Notes:
* Blenfont is used for drawing the text, nicely anti-aliased.
* A monospace truetype font was added, since that is needed for
  the text editor. It's Bitstream Vera Sans Mono. This is the
  default gnome terminal font, but it doesn't fit entirely well
  with the other font I think, can be changed easily of course.
* Clipboard copy/cut/paste now always uses the system clipboard,
  the code for the own cut buffer was removed.
* The interface buttons should support copy/cut/paste again now
  as well.
* WM_clipboard_text_get/WM_clipboard_text_set were added to the
  windowmanager code.
* Find panel is now a kind of second header, instead of a panel.
  This needs especially a way to start editing the text field
  immediately on open still.
* Operators are independent of the actual space when possible,
  was a bit of puzzling but got it solved nice with notifiers,
  and some lazy init for syntax highlight in the drawing code.
* RNA was created for the text editor space and used for buttons.
* Operators:
    * New, Open, Reload, Save, Save As, Make Internal
    * Run Script, Refresh Pyconstraints
    * Copy, Cut, Paste
    * Convert Whitespace, Uncomment, Comment, Indent, Unindent
    * Line Break, Insert

    * Select Line, Select All

	* Scroll, Scroll Bar, Set Cursor, Line Number
    * Find and Replace, Find, Replace, Find Set Selected,
	  Replace Set Selected
    * To 3D Object
    * Resolve Conflict

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

												* New string property subtype: PASSWORD
When this new subtypes is used, then string of property is hidden using
asterisks, e.g.: mysecretpassword -> ****************
This code was reviewed and modified by Brecht. Thanks very much:
 - https://codereview.appspot.com/6713044/
This new subtype of string property is intended mostly for Add-on developers
writing Add-on which communicates with some server (http, sql, ftp, verse,
etc.). When this server requires user authentication and user has to type
username and password, then current API didn't allow to type 'hidden' password,
e.g. when you want to demonstrate this script, then everybody can see this
security password. Some examples of Add-on which could use this new subtype:
 - On-line database of textures
 - Integration of render farm
 - Integration of Verse
Security Notes:
 - You can copy paste hiddent string of property from text input using (Ctrl-C, Ctrl-V),
but you can do this in other GUI toolkits too (this behavior it is widely used).
 - Text of string property is stored in plain text, but it is widely used in other
GUI toolkits (Qt, Gtk, etc.).

etc.). When this server requires user authentication and user has to type
username and password, then current API didn't allow to type 'hidden' password,
e.g. when you want to demonstrate this script, then everybody can see this
security password. Some examples of Add-on which could use this new subtype:
 - On-line database of textures
 - Integration of render farm
 - Integration of Verse
Security Notes:
 - You can copy paste hiddent string of property from text input using (Ctrl-C, Ctrl-V),
but you can do this in other GUI toolkits too (this behavior it is widely used).
 - Text of string property is stored in plain text, but it is widely used in other
GUI toolkits (Qt, Gtk, etc.).

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

UI: don't use operators anymore for handling user interface events, but rather
a special UI handler which makes the code clearer. This UI handler is attached
to the region along with other handlers, and also gets a callback when all
handlers for the region are removed to ensure things are properly cleaned up.
This should fix XXX's in the UI code related to events and context switching.
Most of the changes are in interface_handlers.c, which was renamed from
interface_ops.c, to convert operators to the UI handler. UI code notes:
* uiBeginBlock/uiEndBlock/uiFreeBlocks now takes a context argument, this is
  required to properly cancel things like timers or tooltips when the region
  gets removed.
* UI_add_region_handlers will add the region level UI handlers, to be used
  when adding keymap handlers etc. This replaces the UI keymap.
* When the UI code starts a modal interaction (number sliding, text editing,
  opening a menu, ..), it will add an UI handler at the window level which
  will block events.
Windowmanager changes:
* Added an UI handler next to the existing keymap and operator modal handlers.
  It has an event handling and remove callback, and like operator modal handlers
  will remember the area and region if it is registered at the window level.
* Removed the MESSAGE event.
* Operator cancel and UI handler remove callbacks now get the
  window/area/region restored in the context, like the operator modal and UI
  handler event callbacks.
* Regions now receive MOUSEMOVE events for the mouse going outside of the
  region. This was already happening for areas, but UI buttons are at the region
  level so we need it there.
Issues:
* Tooltips and menus stay open when switching to another window, and button
  highlight doesn't work without moving the mouse first when Blender starts up.
  I tried using some events like Q_FIRSTTIME, WINTHAW, but those don't seem to
  arrive..
* Timeline header buttons seem to be moving one pixel or so sometimes when
  interacting with them.
* Seems not due to this commit, but UI and keymap handlers are leaking. It
  seems that handlers are being added to regions in all screens, also in regions
  of areas that are not visible, but these handlers are not removed. Probably
  there should only be handlers in visible regions?

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

UI: don't use operators anymore for handling user interface events, but rather
a special UI handler which makes the code clearer. This UI handler is attached
to the region along with other handlers, and also gets a callback when all
handlers for the region are removed to ensure things are properly cleaned up.
This should fix XXX's in the UI code related to events and context switching.
Most of the changes are in interface_handlers.c, which was renamed from
interface_ops.c, to convert operators to the UI handler. UI code notes:
* uiBeginBlock/uiEndBlock/uiFreeBlocks now takes a context argument, this is
  required to properly cancel things like timers or tooltips when the region
  gets removed.
* UI_add_region_handlers will add the region level UI handlers, to be used
  when adding keymap handlers etc. This replaces the UI keymap.
* When the UI code starts a modal interaction (number sliding, text editing,
  opening a menu, ..), it will add an UI handler at the window level which
  will block events.
Windowmanager changes:
* Added an UI handler next to the existing keymap and operator modal handlers.
  It has an event handling and remove callback, and like operator modal handlers
  will remember the area and region if it is registered at the window level.
* Removed the MESSAGE event.
* Operator cancel and UI handler remove callbacks now get the
  window/area/region restored in the context, like the operator modal and UI
  handler event callbacks.
* Regions now receive MOUSEMOVE events for the mouse going outside of the
  region. This was already happening for areas, but UI buttons are at the region
  level so we need it there.
Issues:
* Tooltips and menus stay open when switching to another window, and button
  highlight doesn't work without moving the mouse first when Blender starts up.
  I tried using some events like Q_FIRSTTIME, WINTHAW, but those don't seem to
  arrive..
* Timeline header buttons seem to be moving one pixel or so sometimes when
  interacting with them.
* Seems not due to this commit, but UI and keymap handlers are leaking. It
  seems that handlers are being added to regions in all screens, also in regions
  of areas that are not visible, but these handlers are not removed. Probably
  there should only be handlers in visible regions?

												* New string property subtype: PASSWORD
When this new subtypes is used, then string of property is hidden using
asterisks, e.g.: mysecretpassword -> ****************
This code was reviewed and modified by Brecht. Thanks very much:
 - https://codereview.appspot.com/6713044/
This new subtype of string property is intended mostly for Add-on developers
writing Add-on which communicates with some server (http, sql, ftp, verse,
etc.). When this server requires user authentication and user has to type
username and password, then current API didn't allow to type 'hidden' password,
e.g. when you want to demonstrate this script, then everybody can see this
security password. Some examples of Add-on which could use this new subtype:
 - On-line database of textures
 - Integration of render farm
 - Integration of Verse
Security Notes:
 - You can copy paste hiddent string of property from text input using (Ctrl-C, Ctrl-V),
but you can do this in other GUI toolkits too (this behavior it is widely used).
 - Text of string property is stored in plain text, but it is widely used in other
GUI toolkits (Qt, Gtk, etc.).
Simple examples:

												BugFix:
[#20854] PROPERTIES STAMP: Rendering stamp flickers in output renders
Blenfont was not thread safe, that is why one thread can change
the font properties (size, dpi, color, etc) at the same time
that the stamp draw on the image, and then the problem.
To make blenfont thread safe I have to change two important things:
1) Every BLF_* function take one argument, the font id.
2) We have two new function to make font "thread safe":
	BLF_load_unique
	BLF_load_mem_unique
This two function are for case like stamp, that need and own font
that don't share the glyph cache, so can draw without problem
in a different thread.
Why the BLF_*_unique function ?
Because blenfont keep only one copy of a font and keep a list of
"glyph cache". Every glyph cache have size and dpi, so if two
different thread access the same font at the same time, they can
change value and finish with something like the stamp problem.
Why don't remove the glyph cache ?
Because if we do that, we finish with a font object for every size
and dpi, and the stamp is really a special case that happen in
the rendering process, so I really thing is better keep the
glyph cache and make this two new function to handle this
special case.
(When I say "font object" I mean have the same freetype font multiple
times just to have differents size and dpi)
As Matt point we still can have one case that two thread access
the BLF_*_unique function at the same time, but I am looking to
fix this with some class of thread lock.
For now I test and work fine, so if some one found problem, please
let me know.
Campbell I have to change the python api (python/generic/blf_api.c)
to the new syntax, so maybe you can take a look at this.

* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.

  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a

* Menus, color chooser, tooltips etc all create screen level regions. Such menu

												BugFix:
[#20854] PROPERTIES STAMP: Rendering stamp flickers in output renders
Blenfont was not thread safe, that is why one thread can change
the font properties (size, dpi, color, etc) at the same time
that the stamp draw on the image, and then the problem.
To make blenfont thread safe I have to change two important things:
1) Every BLF_* function take one argument, the font id.
2) We have two new function to make font "thread safe":
	BLF_load_unique
	BLF_load_mem_unique
This two function are for case like stamp, that need and own font
that don't share the glyph cache, so can draw without problem
in a different thread.
Why the BLF_*_unique function ?
Because blenfont keep only one copy of a font and keep a list of
"glyph cache". Every glyph cache have size and dpi, so if two
different thread access the same font at the same time, they can
change value and finish with something like the stamp problem.
Why don't remove the glyph cache ?
Because if we do that, we finish with a font object for every size
and dpi, and the stamp is really a special case that happen in
the rendering process, so I really thing is better keep the
glyph cache and make this two new function to handle this
special case.
(When I say "font object" I mean have the same freetype font multiple
times just to have differents size and dpi)
As Matt point we still can have one case that two thread access
the BLF_*_unique function at the same time, but I am looking to
fix this with some class of thread lock.
For now I test and work fine, so if some one found problem, please
let me know.
Campbell I have to change the python api (python/generic/blf_api.c)
to the new syntax, so maybe you can take a look at this.

asterisks, e.g.: mysecretpassword -> ****************
This code was reviewed and modified by Brecht. Thanks very much:
 - https://codereview.appspot.com/6713044/
This new subtype of string property is intended mostly for Add-on developers
writing Add-on which communicates with some server (http, sql, ftp, verse,
etc.). When this server requires user authentication and user has to type
username and password, then current API didn't allow to type 'hidden' password,
e.g. when you want to demonstrate this script, then everybody can see this
security password. Some examples of Add-on which could use this new subtype:
 - On-line database of textures
 - Integration of render farm
 - Integration of Verse
Security Notes:
 - You can copy paste hiddent string of property from text input using (Ctrl-C, Ctrl-V),
but you can do this in other GUI toolkits too (this behavior it is widely used).
 - Text of string property is stored in plain text, but it is widely used in other
GUI toolkits (Qt, Gtk, etc.).
Simple examples:

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

UI: don't use operators anymore for handling user interface events, but rather
a special UI handler which makes the code clearer. This UI handler is attached
to the region along with other handlers, and also gets a callback when all
handlers for the region are removed to ensure things are properly cleaned up.
This should fix XXX's in the UI code related to events and context switching.
Most of the changes are in interface_handlers.c, which was renamed from
interface_ops.c, to convert operators to the UI handler. UI code notes:
* uiBeginBlock/uiEndBlock/uiFreeBlocks now takes a context argument, this is
  required to properly cancel things like timers or tooltips when the region
  gets removed.
* UI_add_region_handlers will add the region level UI handlers, to be used
  when adding keymap handlers etc. This replaces the UI keymap.
* When the UI code starts a modal interaction (number sliding, text editing,
  opening a menu, ..), it will add an UI handler at the window level which
  will block events.
Windowmanager changes:
* Added an UI handler next to the existing keymap and operator modal handlers.
  It has an event handling and remove callback, and like operator modal handlers
  will remember the area and region if it is registered at the window level.
* Removed the MESSAGE event.
* Operator cancel and UI handler remove callbacks now get the
  window/area/region restored in the context, like the operator modal and UI
  handler event callbacks.
* Regions now receive MOUSEMOVE events for the mouse going outside of the
  region. This was already happening for areas, but UI buttons are at the region
  level so we need it there.
Issues:
* Tooltips and menus stay open when switching to another window, and button
  highlight doesn't work without moving the mouse first when Blender starts up.
  I tried using some events like Q_FIRSTTIME, WINTHAW, but those don't seem to
  arrive..
* Timeline header buttons seem to be moving one pixel or so sometimes when
  interacting with them.
* Seems not due to this commit, but UI and keymap handlers are leaking. It
  seems that handlers are being added to regions in all screens, also in regions
  of areas that are not visible, but these handlers are not removed. Probably
  there should only be handlers in visible regions?

UI: don't use operators anymore for handling user interface events, but rather
a special UI handler which makes the code clearer. This UI handler is attached
to the region along with other handlers, and also gets a callback when all
handlers for the region are removed to ensure things are properly cleaned up.
This should fix XXX's in the UI code related to events and context switching.
Most of the changes are in interface_handlers.c, which was renamed from
interface_ops.c, to convert operators to the UI handler. UI code notes:
* uiBeginBlock/uiEndBlock/uiFreeBlocks now takes a context argument, this is
  required to properly cancel things like timers or tooltips when the region
  gets removed.
* UI_add_region_handlers will add the region level UI handlers, to be used
  when adding keymap handlers etc. This replaces the UI keymap.
* When the UI code starts a modal interaction (number sliding, text editing,
  opening a menu, ..), it will add an UI handler at the window level which
  will block events.
Windowmanager changes:
* Added an UI handler next to the existing keymap and operator modal handlers.
  It has an event handling and remove callback, and like operator modal handlers
  will remember the area and region if it is registered at the window level.
* Removed the MESSAGE event.
* Operator cancel and UI handler remove callbacks now get the
  window/area/region restored in the context, like the operator modal and UI
  handler event callbacks.
* Regions now receive MOUSEMOVE events for the mouse going outside of the
  region. This was already happening for areas, but UI buttons are at the region
  level so we need it there.
Issues:
* Tooltips and menus stay open when switching to another window, and button
  highlight doesn't work without moving the mouse first when Blender starts up.
  I tried using some events like Q_FIRSTTIME, WINTHAW, but those don't seem to
  arrive..
* Timeline header buttons seem to be moving one pixel or so sometimes when
  interacting with them.
* Seems not due to this commit, but UI and keymap handlers are leaking. It
  seems that handlers are being added to regions in all screens, also in regions
  of areas that are not visible, but these handlers are not removed. Probably
  there should only be handlers in visible regions?

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern

* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

Port of part of the Interface code to 2.50.

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

UI: don't use operators anymore for handling user interface events, but rather
a special UI handler which makes the code clearer. This UI handler is attached
to the region along with other handlers, and also gets a callback when all
handlers for the region are removed to ensure things are properly cleaned up.
This should fix XXX's in the UI code related to events and context switching.
Most of the changes are in interface_handlers.c, which was renamed from
interface_ops.c, to convert operators to the UI handler. UI code notes:
* uiBeginBlock/uiEndBlock/uiFreeBlocks now takes a context argument, this is
  required to properly cancel things like timers or tooltips when the region
  gets removed.
* UI_add_region_handlers will add the region level UI handlers, to be used
  when adding keymap handlers etc. This replaces the UI keymap.
* When the UI code starts a modal interaction (number sliding, text editing,
  opening a menu, ..), it will add an UI handler at the window level which
  will block events.
Windowmanager changes:
* Added an UI handler next to the existing keymap and operator modal handlers.
  It has an event handling and remove callback, and like operator modal handlers
  will remember the area and region if it is registered at the window level.
* Removed the MESSAGE event.
* Operator cancel and UI handler remove callbacks now get the
  window/area/region restored in the context, like the operator modal and UI
  handler event callbacks.
* Regions now receive MOUSEMOVE events for the mouse going outside of the
  region. This was already happening for areas, but UI buttons are at the region
  level so we need it there.
Issues:
* Tooltips and menus stay open when switching to another window, and button
  highlight doesn't work without moving the mouse first when Blender starts up.
  I tried using some events like Q_FIRSTTIME, WINTHAW, but those don't seem to
  arrive..
* Timeline header buttons seem to be moving one pixel or so sometimes when
  interacting with them.
* Seems not due to this commit, but UI and keymap handlers are leaking. It
  seems that handlers are being added to regions in all screens, also in regions
  of areas that are not visible, but these handlers are not removed. Probably
  there should only be handlers in visible regions?

												2.5: Text Editor back.
There was very little structure in this code, using many globals
and duplicated code. Now it should be better structured. Most
things should work, the main parts that are not back yet are the
python plugins and markers. Notes:
* Blenfont is used for drawing the text, nicely anti-aliased.
* A monospace truetype font was added, since that is needed for
  the text editor. It's Bitstream Vera Sans Mono. This is the
  default gnome terminal font, but it doesn't fit entirely well
  with the other font I think, can be changed easily of course.
* Clipboard copy/cut/paste now always uses the system clipboard,
  the code for the own cut buffer was removed.
* The interface buttons should support copy/cut/paste again now
  as well.
* WM_clipboard_text_get/WM_clipboard_text_set were added to the
  windowmanager code.
* Find panel is now a kind of second header, instead of a panel.
  This needs especially a way to start editing the text field
  immediately on open still.
* Operators are independent of the actual space when possible,
  was a bit of puzzling but got it solved nice with notifiers,
  and some lazy init for syntax highlight in the drawing code.
* RNA was created for the text editor space and used for buttons.
* Operators:
    * New, Open, Reload, Save, Save As, Make Internal
    * Run Script, Refresh Pyconstraints
    * Copy, Cut, Paste
    * Convert Whitespace, Uncomment, Comment, Indent, Unindent
    * Line Break, Insert

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

												2.5: Text Editor back.
There was very little structure in this code, using many globals
and duplicated code. Now it should be better structured. Most
things should work, the main parts that are not back yet are the
python plugins and markers. Notes:
* Blenfont is used for drawing the text, nicely anti-aliased.
* A monospace truetype font was added, since that is needed for
  the text editor. It's Bitstream Vera Sans Mono. This is the
  default gnome terminal font, but it doesn't fit entirely well
  with the other font I think, can be changed easily of course.
* Clipboard copy/cut/paste now always uses the system clipboard,
  the code for the own cut buffer was removed.
* The interface buttons should support copy/cut/paste again now
  as well.
* WM_clipboard_text_get/WM_clipboard_text_set were added to the
  windowmanager code.
* Find panel is now a kind of second header, instead of a panel.
  This needs especially a way to start editing the text field
  immediately on open still.
* Operators are independent of the actual space when possible,
  was a bit of puzzling but got it solved nice with notifiers,
  and some lazy init for syntax highlight in the drawing code.
* RNA was created for the text editor space and used for buttons.
* Operators:
    * New, Open, Reload, Save, Save As, Make Internal
    * Run Script, Refresh Pyconstraints
    * Copy, Cut, Paste
    * Convert Whitespace, Uncomment, Comment, Indent, Unindent

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager

* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and

UI: don't use operators anymore for handling user interface events, but rather
a special UI handler which makes the code clearer. This UI handler is attached
to the region along with other handlers, and also gets a callback when all
handlers for the region are removed to ensure things are properly cleaned up.
This should fix XXX's in the UI code related to events and context switching.
Most of the changes are in interface_handlers.c, which was renamed from
interface_ops.c, to convert operators to the UI handler. UI code notes:
* uiBeginBlock/uiEndBlock/uiFreeBlocks now takes a context argument, this is
  required to properly cancel things like timers or tooltips when the region
  gets removed.
* UI_add_region_handlers will add the region level UI handlers, to be used
  when adding keymap handlers etc. This replaces the UI keymap.
* When the UI code starts a modal interaction (number sliding, text editing,
  opening a menu, ..), it will add an UI handler at the window level which
  will block events.
Windowmanager changes:
* Added an UI handler next to the existing keymap and operator modal handlers.
  It has an event handling and remove callback, and like operator modal handlers
  will remember the area and region if it is registered at the window level.
* Removed the MESSAGE event.
* Operator cancel and UI handler remove callbacks now get the
  window/area/region restored in the context, like the operator modal and UI
  handler event callbacks.
* Regions now receive MOUSEMOVE events for the mouse going outside of the
  region. This was already happening for areas, but UI buttons are at the region
  level so we need it there.
Issues:
* Tooltips and menus stay open when switching to another window, and button
  highlight doesn't work without moving the mouse first when Blender starts up.
  I tried using some events like Q_FIRSTTIME, WINTHAW, but those don't seem to
  arrive..
* Timeline header buttons seem to be moving one pixel or so sometimes when
  interacting with them.
* Seems not due to this commit, but UI and keymap handlers are leaking. It
  seems that handlers are being added to regions in all screens, also in regions
  of areas that are not visible, but these handlers are not removed. Probably
  there should only be handlers in visible regions?

* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

UI: don't use operators anymore for handling user interface events, but rather
a special UI handler which makes the code clearer. This UI handler is attached
to the region along with other handlers, and also gets a callback when all
handlers for the region are removed to ensure things are properly cleaned up.
This should fix XXX's in the UI code related to events and context switching.
Most of the changes are in interface_handlers.c, which was renamed from
interface_ops.c, to convert operators to the UI handler. UI code notes:
* uiBeginBlock/uiEndBlock/uiFreeBlocks now takes a context argument, this is
  required to properly cancel things like timers or tooltips when the region
  gets removed.
* UI_add_region_handlers will add the region level UI handlers, to be used
  when adding keymap handlers etc. This replaces the UI keymap.
* When the UI code starts a modal interaction (number sliding, text editing,
  opening a menu, ..), it will add an UI handler at the window level which
  will block events.
Windowmanager changes:
* Added an UI handler next to the existing keymap and operator modal handlers.
  It has an event handling and remove callback, and like operator modal handlers
  will remember the area and region if it is registered at the window level.
* Removed the MESSAGE event.
* Operator cancel and UI handler remove callbacks now get the
  window/area/region restored in the context, like the operator modal and UI
  handler event callbacks.
* Regions now receive MOUSEMOVE events for the mouse going outside of the
  region. This was already happening for areas, but UI buttons are at the region
  level so we need it there.
Issues:
* Tooltips and menus stay open when switching to another window, and button
  highlight doesn't work without moving the mouse first when Blender starts up.
  I tried using some events like Q_FIRSTTIME, WINTHAW, but those don't seem to
  arrive..
* Timeline header buttons seem to be moving one pixel or so sometimes when
  interacting with them.
* Seems not due to this commit, but UI and keymap handlers are leaking. It
  seems that handlers are being added to regions in all screens, also in regions
  of areas that are not visible, but these handlers are not removed. Probably
  there should only be handlers in visible regions?

* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

UI: don't use operators anymore for handling user interface events, but rather
a special UI handler which makes the code clearer. This UI handler is attached
to the region along with other handlers, and also gets a callback when all
handlers for the region are removed to ensure things are properly cleaned up.
This should fix XXX's in the UI code related to events and context switching.
Most of the changes are in interface_handlers.c, which was renamed from
interface_ops.c, to convert operators to the UI handler. UI code notes:
* uiBeginBlock/uiEndBlock/uiFreeBlocks now takes a context argument, this is
  required to properly cancel things like timers or tooltips when the region
  gets removed.
* UI_add_region_handlers will add the region level UI handlers, to be used
  when adding keymap handlers etc. This replaces the UI keymap.
* When the UI code starts a modal interaction (number sliding, text editing,
  opening a menu, ..), it will add an UI handler at the window level which
  will block events.
Windowmanager changes:
* Added an UI handler next to the existing keymap and operator modal handlers.
  It has an event handling and remove callback, and like operator modal handlers
  will remember the area and region if it is registered at the window level.
* Removed the MESSAGE event.
* Operator cancel and UI handler remove callbacks now get the
  window/area/region restored in the context, like the operator modal and UI
  handler event callbacks.
* Regions now receive MOUSEMOVE events for the mouse going outside of the
  region. This was already happening for areas, but UI buttons are at the region
  level so we need it there.
Issues:
* Tooltips and menus stay open when switching to another window, and button
  highlight doesn't work without moving the mouse first when Blender starts up.
  I tried using some events like Q_FIRSTTIME, WINTHAW, but those don't seem to
  arrive..
* Timeline header buttons seem to be moving one pixel or so sometimes when
  interacting with them.
* Seems not due to this commit, but UI and keymap handlers are leaking. It
  seems that handlers are being added to regions in all screens, also in regions
  of areas that are not visible, but these handlers are not removed. Probably
  there should only be handlers in visible regions?

  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

Testing:

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.

  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct

UI: don't use operators anymore for handling user interface events, but rather
a special UI handler which makes the code clearer. This UI handler is attached
to the region along with other handlers, and also gets a callback when all
handlers for the region are removed to ensure things are properly cleaned up.
This should fix XXX's in the UI code related to events and context switching.
Most of the changes are in interface_handlers.c, which was renamed from
interface_ops.c, to convert operators to the UI handler. UI code notes:
* uiBeginBlock/uiEndBlock/uiFreeBlocks now takes a context argument, this is
  required to properly cancel things like timers or tooltips when the region
  gets removed.
* UI_add_region_handlers will add the region level UI handlers, to be used
  when adding keymap handlers etc. This replaces the UI keymap.
* When the UI code starts a modal interaction (number sliding, text editing,
  opening a menu, ..), it will add an UI handler at the window level which
  will block events.
Windowmanager changes:
* Added an UI handler next to the existing keymap and operator modal handlers.
  It has an event handling and remove callback, and like operator modal handlers
  will remember the area and region if it is registered at the window level.
* Removed the MESSAGE event.
* Operator cancel and UI handler remove callbacks now get the
  window/area/region restored in the context, like the operator modal and UI
  handler event callbacks.
* Regions now receive MOUSEMOVE events for the mouse going outside of the
  region. This was already happening for areas, but UI buttons are at the region
  level so we need it there.
Issues:
* Tooltips and menus stay open when switching to another window, and button
  highlight doesn't work without moving the mouse first when Blender starts up.
  I tried using some events like Q_FIRSTTIME, WINTHAW, but those don't seem to
  arrive..
* Timeline header buttons seem to be moving one pixel or so sometimes when
  interacting with them.
* Seems not due to this commit, but UI and keymap handlers are leaking. It
  seems that handlers are being added to regions in all screens, also in regions
  of areas that are not visible, but these handlers are not removed. Probably
  there should only be handlers in visible regions?

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

UI: don't use operators anymore for handling user interface events, but rather
a special UI handler which makes the code clearer. This UI handler is attached
to the region along with other handlers, and also gets a callback when all
handlers for the region are removed to ensure things are properly cleaned up.
This should fix XXX's in the UI code related to events and context switching.
Most of the changes are in interface_handlers.c, which was renamed from
interface_ops.c, to convert operators to the UI handler. UI code notes:
* uiBeginBlock/uiEndBlock/uiFreeBlocks now takes a context argument, this is
  required to properly cancel things like timers or tooltips when the region
  gets removed.
* UI_add_region_handlers will add the region level UI handlers, to be used
  when adding keymap handlers etc. This replaces the UI keymap.
* When the UI code starts a modal interaction (number sliding, text editing,
  opening a menu, ..), it will add an UI handler at the window level which
  will block events.
Windowmanager changes:
* Added an UI handler next to the existing keymap and operator modal handlers.
  It has an event handling and remove callback, and like operator modal handlers
  will remember the area and region if it is registered at the window level.
* Removed the MESSAGE event.
* Operator cancel and UI handler remove callbacks now get the
  window/area/region restored in the context, like the operator modal and UI
  handler event callbacks.
* Regions now receive MOUSEMOVE events for the mouse going outside of the
  region. This was already happening for areas, but UI buttons are at the region
  level so we need it there.
Issues:
* Tooltips and menus stay open when switching to another window, and button
  highlight doesn't work without moving the mouse first when Blender starts up.
  I tried using some events like Q_FIRSTTIME, WINTHAW, but those don't seem to
  arrive..
* Timeline header buttons seem to be moving one pixel or so sometimes when
  interacting with them.
* Seems not due to this commit, but UI and keymap handlers are leaking. It
  seems that handlers are being added to regions in all screens, also in regions
  of areas that are not visible, but these handlers are not removed. Probably
  there should only be handlers in visible regions?

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is

  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to

  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it

  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.

UI: don't use operators anymore for handling user interface events, but rather
a special UI handler which makes the code clearer. This UI handler is attached
to the region along with other handlers, and also gets a callback when all
handlers for the region are removed to ensure things are properly cleaned up.
This should fix XXX's in the UI code related to events and context switching.
Most of the changes are in interface_handlers.c, which was renamed from
interface_ops.c, to convert operators to the UI handler. UI code notes:
* uiBeginBlock/uiEndBlock/uiFreeBlocks now takes a context argument, this is
  required to properly cancel things like timers or tooltips when the region
  gets removed.
* UI_add_region_handlers will add the region level UI handlers, to be used
  when adding keymap handlers etc. This replaces the UI keymap.
* When the UI code starts a modal interaction (number sliding, text editing,
  opening a menu, ..), it will add an UI handler at the window level which
  will block events.
Windowmanager changes:
* Added an UI handler next to the existing keymap and operator modal handlers.
  It has an event handling and remove callback, and like operator modal handlers
  will remember the area and region if it is registered at the window level.
* Removed the MESSAGE event.
* Operator cancel and UI handler remove callbacks now get the
  window/area/region restored in the context, like the operator modal and UI
  handler event callbacks.
* Regions now receive MOUSEMOVE events for the mouse going outside of the
  region. This was already happening for areas, but UI buttons are at the region
  level so we need it there.
Issues:
* Tooltips and menus stay open when switching to another window, and button
  highlight doesn't work without moving the mouse first when Blender starts up.
  I tried using some events like Q_FIRSTTIME, WINTHAW, but those don't seem to
  arrive..
* Timeline header buttons seem to be moving one pixel or so sometimes when
  interacting with them.
* Seems not due to this commit, but UI and keymap handlers are leaking. It
  seems that handlers are being added to regions in all screens, also in regions
  of areas that are not visible, but these handlers are not removed. Probably
  there should only be handlers in visible regions?

  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.

* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.

UI: don't use operators anymore for handling user interface events, but rather
a special UI handler which makes the code clearer. This UI handler is attached
to the region along with other handlers, and also gets a callback when all
handlers for the region are removed to ensure things are properly cleaned up.
This should fix XXX's in the UI code related to events and context switching.
Most of the changes are in interface_handlers.c, which was renamed from
interface_ops.c, to convert operators to the UI handler. UI code notes:
* uiBeginBlock/uiEndBlock/uiFreeBlocks now takes a context argument, this is
  required to properly cancel things like timers or tooltips when the region
  gets removed.
* UI_add_region_handlers will add the region level UI handlers, to be used
  when adding keymap handlers etc. This replaces the UI keymap.
* When the UI code starts a modal interaction (number sliding, text editing,
  opening a menu, ..), it will add an UI handler at the window level which
  will block events.
Windowmanager changes:
* Added an UI handler next to the existing keymap and operator modal handlers.
  It has an event handling and remove callback, and like operator modal handlers
  will remember the area and region if it is registered at the window level.
* Removed the MESSAGE event.
* Operator cancel and UI handler remove callbacks now get the
  window/area/region restored in the context, like the operator modal and UI
  handler event callbacks.
* Regions now receive MOUSEMOVE events for the mouse going outside of the
  region. This was already happening for areas, but UI buttons are at the region
  level so we need it there.
Issues:
* Tooltips and menus stay open when switching to another window, and button
  highlight doesn't work without moving the mouse first when Blender starts up.
  I tried using some events like Q_FIRSTTIME, WINTHAW, but those don't seem to
  arrive..
* Timeline header buttons seem to be moving one pixel or so sometimes when
  interacting with them.
* Seems not due to this commit, but UI and keymap handlers are leaking. It
  seems that handlers are being added to regions in all screens, also in regions
  of areas that are not visible, but these handlers are not removed. Probably
  there should only be handlers in visible regions?

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

UI: don't use operators anymore for handling user interface events, but rather
a special UI handler which makes the code clearer. This UI handler is attached
to the region along with other handlers, and also gets a callback when all
handlers for the region are removed to ensure things are properly cleaned up.
This should fix XXX's in the UI code related to events and context switching.
Most of the changes are in interface_handlers.c, which was renamed from
interface_ops.c, to convert operators to the UI handler. UI code notes:
* uiBeginBlock/uiEndBlock/uiFreeBlocks now takes a context argument, this is
  required to properly cancel things like timers or tooltips when the region
  gets removed.
* UI_add_region_handlers will add the region level UI handlers, to be used
  when adding keymap handlers etc. This replaces the UI keymap.
* When the UI code starts a modal interaction (number sliding, text editing,
  opening a menu, ..), it will add an UI handler at the window level which
  will block events.
Windowmanager changes:
* Added an UI handler next to the existing keymap and operator modal handlers.
  It has an event handling and remove callback, and like operator modal handlers
  will remember the area and region if it is registered at the window level.
* Removed the MESSAGE event.
* Operator cancel and UI handler remove callbacks now get the
  window/area/region restored in the context, like the operator modal and UI
  handler event callbacks.
* Regions now receive MOUSEMOVE events for the mouse going outside of the
  region. This was already happening for areas, but UI buttons are at the region
  level so we need it there.
Issues:
* Tooltips and menus stay open when switching to another window, and button
  highlight doesn't work without moving the mouse first when Blender starts up.
  I tried using some events like Q_FIRSTTIME, WINTHAW, but those don't seem to
  arrive..
* Timeline header buttons seem to be moving one pixel or so sometimes when
  interacting with them.
* Seems not due to this commit, but UI and keymap handlers are leaking. It
  seems that handlers are being added to regions in all screens, also in regions
  of areas that are not visible, but these handlers are not removed. Probably
  there should only be handlers in visible regions?

  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

UI: don't use operators anymore for handling user interface events, but rather
a special UI handler which makes the code clearer. This UI handler is attached
to the region along with other handlers, and also gets a callback when all
handlers for the region are removed to ensure things are properly cleaned up.
This should fix XXX's in the UI code related to events and context switching.
Most of the changes are in interface_handlers.c, which was renamed from
interface_ops.c, to convert operators to the UI handler. UI code notes:
* uiBeginBlock/uiEndBlock/uiFreeBlocks now takes a context argument, this is
  required to properly cancel things like timers or tooltips when the region
  gets removed.
* UI_add_region_handlers will add the region level UI handlers, to be used
  when adding keymap handlers etc. This replaces the UI keymap.
* When the UI code starts a modal interaction (number sliding, text editing,
  opening a menu, ..), it will add an UI handler at the window level which
  will block events.
Windowmanager changes:
* Added an UI handler next to the existing keymap and operator modal handlers.
  It has an event handling and remove callback, and like operator modal handlers
  will remember the area and region if it is registered at the window level.
* Removed the MESSAGE event.
* Operator cancel and UI handler remove callbacks now get the
  window/area/region restored in the context, like the operator modal and UI
  handler event callbacks.
* Regions now receive MOUSEMOVE events for the mouse going outside of the
  region. This was already happening for areas, but UI buttons are at the region
  level so we need it there.
Issues:
* Tooltips and menus stay open when switching to another window, and button
  highlight doesn't work without moving the mouse first when Blender starts up.
  I tried using some events like Q_FIRSTTIME, WINTHAW, but those don't seem to
  arrive..
* Timeline header buttons seem to be moving one pixel or so sometimes when
  interacting with them.
* Seems not due to this commit, but UI and keymap handlers are leaking. It
  seems that handlers are being added to regions in all screens, also in regions
  of areas that are not visible, but these handlers are not removed. Probably
  there should only be handlers in visible regions?

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.

  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.

* Menus, color chooser, tooltips etc all create screen level regions. Such menu

* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted

												2.5: UI & Menus
* Cleaned up UI_interface.h a bit, and added some comments to
  organize things a bit and indicate what should be used when.
* uiMenu* functions can now be used to create menus for headers
  too, this is done with a uiDefMenuBut, which takes a pointer
  to a uiMenuCreateFunc, that will then call uiMenu* functions.
* Renamed uiMenuBegin/End to uiPupMenuBegin/End, as these are
  specific to making popup menus. Will convert the other
  conformation popup menu functions to use this too so we can
  remove some code.
* Extended uiMenu functions, now there is is also:
  BooleanO, FloatO, BooleanR, EnumR, LevelEnumR, Separator.
* Converted image window headers to use uiMenu functions, simplifies
  menu code further here. Did not remove the uiDefMenu functions as
  they are used in sequencer/view3d in some places now (will fix).
* Also tried to simplify and fix bounds computation a bit better
  for popup menus. It tried to find out in advance what the size
  of the menu was but this is difficult with keymap strings in
  there, now uiPopupBoundsBlock can figure this out afterwards and
  ensure the popup is within the window bounds. Will convert some
  other functions to use this too.

UI: don't use operators anymore for handling user interface events, but rather
a special UI handler which makes the code clearer. This UI handler is attached
to the region along with other handlers, and also gets a callback when all
handlers for the region are removed to ensure things are properly cleaned up.
This should fix XXX's in the UI code related to events and context switching.
Most of the changes are in interface_handlers.c, which was renamed from
interface_ops.c, to convert operators to the UI handler. UI code notes:
* uiBeginBlock/uiEndBlock/uiFreeBlocks now takes a context argument, this is
  required to properly cancel things like timers or tooltips when the region
  gets removed.
* UI_add_region_handlers will add the region level UI handlers, to be used
  when adding keymap handlers etc. This replaces the UI keymap.
* When the UI code starts a modal interaction (number sliding, text editing,
  opening a menu, ..), it will add an UI handler at the window level which
  will block events.
Windowmanager changes:
* Added an UI handler next to the existing keymap and operator modal handlers.
  It has an event handling and remove callback, and like operator modal handlers
  will remember the area and region if it is registered at the window level.
* Removed the MESSAGE event.
* Operator cancel and UI handler remove callbacks now get the
  window/area/region restored in the context, like the operator modal and UI
  handler event callbacks.
* Regions now receive MOUSEMOVE events for the mouse going outside of the
  region. This was already happening for areas, but UI buttons are at the region
  level so we need it there.
Issues:
* Tooltips and menus stay open when switching to another window, and button
  highlight doesn't work without moving the mouse first when Blender starts up.
  I tried using some events like Q_FIRSTTIME, WINTHAW, but those don't seem to
  arrive..
* Timeline header buttons seem to be moving one pixel or so sometimes when
  interacting with them.
* Seems not due to this commit, but UI and keymap handlers are leaking. It
  seems that handlers are being added to regions in all screens, also in regions
  of areas that are not visible, but these handlers are not removed. Probably
  there should only be handlers in visible regions?

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.

UI: don't use operators anymore for handling user interface events, but rather
a special UI handler which makes the code clearer. This UI handler is attached
to the region along with other handlers, and also gets a callback when all
handlers for the region are removed to ensure things are properly cleaned up.
This should fix XXX's in the UI code related to events and context switching.
Most of the changes are in interface_handlers.c, which was renamed from
interface_ops.c, to convert operators to the UI handler. UI code notes:
* uiBeginBlock/uiEndBlock/uiFreeBlocks now takes a context argument, this is
  required to properly cancel things like timers or tooltips when the region
  gets removed.
* UI_add_region_handlers will add the region level UI handlers, to be used
  when adding keymap handlers etc. This replaces the UI keymap.
* When the UI code starts a modal interaction (number sliding, text editing,
  opening a menu, ..), it will add an UI handler at the window level which
  will block events.
Windowmanager changes:
* Added an UI handler next to the existing keymap and operator modal handlers.
  It has an event handling and remove callback, and like operator modal handlers
  will remember the area and region if it is registered at the window level.
* Removed the MESSAGE event.
* Operator cancel and UI handler remove callbacks now get the
  window/area/region restored in the context, like the operator modal and UI
  handler event callbacks.
* Regions now receive MOUSEMOVE events for the mouse going outside of the
  region. This was already happening for areas, but UI buttons are at the region
  level so we need it there.
Issues:
* Tooltips and menus stay open when switching to another window, and button
  highlight doesn't work without moving the mouse first when Blender starts up.
  I tried using some events like Q_FIRSTTIME, WINTHAW, but those don't seem to
  arrive..
* Timeline header buttons seem to be moving one pixel or so sometimes when
  interacting with them.
* Seems not due to this commit, but UI and keymap handlers are leaking. It
  seems that handlers are being added to regions in all screens, also in regions
  of areas that are not visible, but these handlers are not removed. Probably
  there should only be handlers in visible regions?

												2.5: UI & Menus
* Cleaned up UI_interface.h a bit, and added some comments to
  organize things a bit and indicate what should be used when.
* uiMenu* functions can now be used to create menus for headers
  too, this is done with a uiDefMenuBut, which takes a pointer
  to a uiMenuCreateFunc, that will then call uiMenu* functions.
* Renamed uiMenuBegin/End to uiPupMenuBegin/End, as these are
  specific to making popup menus. Will convert the other
  conformation popup menu functions to use this too so we can
  remove some code.
* Extended uiMenu functions, now there is is also:
  BooleanO, FloatO, BooleanR, EnumR, LevelEnumR, Separator.
* Converted image window headers to use uiMenu functions, simplifies
  menu code further here. Did not remove the uiDefMenu functions as
  they are used in sequencer/view3d in some places now (will fix).
* Also tried to simplify and fix bounds computation a bit better
  for popup menus. It tried to find out in advance what the size
  of the menu was but this is difficult with keymap strings in
  there, now uiPopupBoundsBlock can figure this out afterwards and
  ensure the popup is within the window bounds. Will convert some
  other functions to use this too.

This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

UI: don't use operators anymore for handling user interface events, but rather
a special UI handler which makes the code clearer. This UI handler is attached
to the region along with other handlers, and also gets a callback when all
handlers for the region are removed to ensure things are properly cleaned up.
This should fix XXX's in the UI code related to events and context switching.
Most of the changes are in interface_handlers.c, which was renamed from
interface_ops.c, to convert operators to the UI handler. UI code notes:
* uiBeginBlock/uiEndBlock/uiFreeBlocks now takes a context argument, this is
  required to properly cancel things like timers or tooltips when the region
  gets removed.
* UI_add_region_handlers will add the region level UI handlers, to be used
  when adding keymap handlers etc. This replaces the UI keymap.
* When the UI code starts a modal interaction (number sliding, text editing,
  opening a menu, ..), it will add an UI handler at the window level which
  will block events.
Windowmanager changes:
* Added an UI handler next to the existing keymap and operator modal handlers.
  It has an event handling and remove callback, and like operator modal handlers
  will remember the area and region if it is registered at the window level.
* Removed the MESSAGE event.
* Operator cancel and UI handler remove callbacks now get the
  window/area/region restored in the context, like the operator modal and UI
  handler event callbacks.
* Regions now receive MOUSEMOVE events for the mouse going outside of the
  region. This was already happening for areas, but UI buttons are at the region
  level so we need it there.
Issues:
* Tooltips and menus stay open when switching to another window, and button
  highlight doesn't work without moving the mouse first when Blender starts up.
  I tried using some events like Q_FIRSTTIME, WINTHAW, but those don't seem to
  arrive..
* Timeline header buttons seem to be moving one pixel or so sometimes when
  interacting with them.
* Seems not due to this commit, but UI and keymap handlers are leaking. It
  seems that handlers are being added to regions in all screens, also in regions
  of areas that are not visible, but these handlers are not removed. Probably
  there should only be handlers in visible regions?

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

UI: don't use operators anymore for handling user interface events, but rather
a special UI handler which makes the code clearer. This UI handler is attached
to the region along with other handlers, and also gets a callback when all
handlers for the region are removed to ensure things are properly cleaned up.
This should fix XXX's in the UI code related to events and context switching.
Most of the changes are in interface_handlers.c, which was renamed from
interface_ops.c, to convert operators to the UI handler. UI code notes:
* uiBeginBlock/uiEndBlock/uiFreeBlocks now takes a context argument, this is
  required to properly cancel things like timers or tooltips when the region
  gets removed.
* UI_add_region_handlers will add the region level UI handlers, to be used
  when adding keymap handlers etc. This replaces the UI keymap.
* When the UI code starts a modal interaction (number sliding, text editing,
  opening a menu, ..), it will add an UI handler at the window level which
  will block events.
Windowmanager changes:
* Added an UI handler next to the existing keymap and operator modal handlers.
  It has an event handling and remove callback, and like operator modal handlers
  will remember the area and region if it is registered at the window level.
* Removed the MESSAGE event.
* Operator cancel and UI handler remove callbacks now get the
  window/area/region restored in the context, like the operator modal and UI
  handler event callbacks.
* Regions now receive MOUSEMOVE events for the mouse going outside of the
  region. This was already happening for areas, but UI buttons are at the region
  level so we need it there.
Issues:
* Tooltips and menus stay open when switching to another window, and button
  highlight doesn't work without moving the mouse first when Blender starts up.
  I tried using some events like Q_FIRSTTIME, WINTHAW, but those don't seem to
  arrive..
* Timeline header buttons seem to be moving one pixel or so sometimes when
  interacting with them.
* Seems not due to this commit, but UI and keymap handlers are leaking. It
  seems that handlers are being added to regions in all screens, also in regions
  of areas that are not visible, but these handlers are not removed. Probably
  there should only be handlers in visible regions?

  will remember the area and region if it is registered at the window level.
* Removed the MESSAGE event.
* Operator cancel and UI handler remove callbacks now get the
  window/area/region restored in the context, like the operator modal and UI
  handler event callbacks.
* Regions now receive MOUSEMOVE events for the mouse going outside of the
  region. This was already happening for areas, but UI buttons are at the region
  level so we need it there.
Issues:
* Tooltips and menus stay open when switching to another window, and button
  highlight doesn't work without moving the mouse first when Blender starts up.
  I tried using some events like Q_FIRSTTIME, WINTHAW, but those don't seem to
  arrive..
* Timeline header buttons seem to be moving one pixel or so sometimes when
  interacting with them.
* Seems not due to this commit, but UI and keymap handlers are leaking. It
  seems that handlers are being added to regions in all screens, also in regions
  of areas that are not visible, but these handlers are not removed. Probably
  there should only be handlers in visible regions?

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

UI: don't use operators anymore for handling user interface events, but rather
a special UI handler which makes the code clearer. This UI handler is attached
to the region along with other handlers, and also gets a callback when all
handlers for the region are removed to ensure things are properly cleaned up.
This should fix XXX's in the UI code related to events and context switching.
Most of the changes are in interface_handlers.c, which was renamed from
interface_ops.c, to convert operators to the UI handler. UI code notes:
* uiBeginBlock/uiEndBlock/uiFreeBlocks now takes a context argument, this is
  required to properly cancel things like timers or tooltips when the region
  gets removed.
* UI_add_region_handlers will add the region level UI handlers, to be used
  when adding keymap handlers etc. This replaces the UI keymap.
* When the UI code starts a modal interaction (number sliding, text editing,
  opening a menu, ..), it will add an UI handler at the window level which
  will block events.
Windowmanager changes:
* Added an UI handler next to the existing keymap and operator modal handlers.
  It has an event handling and remove callback, and like operator modal handlers
  will remember the area and region if it is registered at the window level.
* Removed the MESSAGE event.
* Operator cancel and UI handler remove callbacks now get the
  window/area/region restored in the context, like the operator modal and UI
  handler event callbacks.
* Regions now receive MOUSEMOVE events for the mouse going outside of the
  region. This was already happening for areas, but UI buttons are at the region
  level so we need it there.
Issues:
* Tooltips and menus stay open when switching to another window, and button
  highlight doesn't work without moving the mouse first when Blender starts up.
  I tried using some events like Q_FIRSTTIME, WINTHAW, but those don't seem to
  arrive..
* Timeline header buttons seem to be moving one pixel or so sometimes when
  interacting with them.
* Seems not due to this commit, but UI and keymap handlers are leaking. It
  seems that handlers are being added to regions in all screens, also in regions
  of areas that are not visible, but these handlers are not removed. Probably
  there should only be handlers in visible regions?

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

UI: don't use operators anymore for handling user interface events, but rather
a special UI handler which makes the code clearer. This UI handler is attached
to the region along with other handlers, and also gets a callback when all
handlers for the region are removed to ensure things are properly cleaned up.
This should fix XXX's in the UI code related to events and context switching.
Most of the changes are in interface_handlers.c, which was renamed from
interface_ops.c, to convert operators to the UI handler. UI code notes:
* uiBeginBlock/uiEndBlock/uiFreeBlocks now takes a context argument, this is
  required to properly cancel things like timers or tooltips when the region
  gets removed.
* UI_add_region_handlers will add the region level UI handlers, to be used
  when adding keymap handlers etc. This replaces the UI keymap.
* When the UI code starts a modal interaction (number sliding, text editing,
  opening a menu, ..), it will add an UI handler at the window level which
  will block events.
Windowmanager changes:
* Added an UI handler next to the existing keymap and operator modal handlers.
  It has an event handling and remove callback, and like operator modal handlers
  will remember the area and region if it is registered at the window level.
* Removed the MESSAGE event.
* Operator cancel and UI handler remove callbacks now get the
  window/area/region restored in the context, like the operator modal and UI
  handler event callbacks.
* Regions now receive MOUSEMOVE events for the mouse going outside of the
  region. This was already happening for areas, but UI buttons are at the region
  level so we need it there.
Issues:
* Tooltips and menus stay open when switching to another window, and button
  highlight doesn't work without moving the mouse first when Blender starts up.
  I tried using some events like Q_FIRSTTIME, WINTHAW, but those don't seem to
  arrive..
* Timeline header buttons seem to be moving one pixel or so sometimes when
  interacting with them.
* Seems not due to this commit, but UI and keymap handlers are leaking. It
  seems that handlers are being added to regions in all screens, also in regions
  of areas that are not visible, but these handlers are not removed. Probably
  there should only be handlers in visible regions?

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.

  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

UI: don't use operators anymore for handling user interface events, but rather
a special UI handler which makes the code clearer. This UI handler is attached
to the region along with other handlers, and also gets a callback when all
handlers for the region are removed to ensure things are properly cleaned up.
This should fix XXX's in the UI code related to events and context switching.
Most of the changes are in interface_handlers.c, which was renamed from
interface_ops.c, to convert operators to the UI handler. UI code notes:
* uiBeginBlock/uiEndBlock/uiFreeBlocks now takes a context argument, this is
  required to properly cancel things like timers or tooltips when the region
  gets removed.
* UI_add_region_handlers will add the region level UI handlers, to be used
  when adding keymap handlers etc. This replaces the UI keymap.
* When the UI code starts a modal interaction (number sliding, text editing,
  opening a menu, ..), it will add an UI handler at the window level which
  will block events.
Windowmanager changes:
* Added an UI handler next to the existing keymap and operator modal handlers.
  It has an event handling and remove callback, and like operator modal handlers
  will remember the area and region if it is registered at the window level.
* Removed the MESSAGE event.
* Operator cancel and UI handler remove callbacks now get the
  window/area/region restored in the context, like the operator modal and UI
  handler event callbacks.
* Regions now receive MOUSEMOVE events for the mouse going outside of the
  region. This was already happening for areas, but UI buttons are at the region
  level so we need it there.
Issues:
* Tooltips and menus stay open when switching to another window, and button
  highlight doesn't work without moving the mouse first when Blender starts up.
  I tried using some events like Q_FIRSTTIME, WINTHAW, but those don't seem to
  arrive..
* Timeline header buttons seem to be moving one pixel or so sometimes when
  interacting with them.
* Seems not due to this commit, but UI and keymap handlers are leaking. It
  seems that handlers are being added to regions in all screens, also in regions
  of areas that are not visible, but these handlers are not removed. Probably
  there should only be handlers in visible regions?

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.

  blocks give a handle to the button that creates it, which will contain the

  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

UI: don't use operators anymore for handling user interface events, but rather
a special UI handler which makes the code clearer. This UI handler is attached
to the region along with other handlers, and also gets a callback when all
handlers for the region are removed to ensure things are properly cleaned up.
This should fix XXX's in the UI code related to events and context switching.
Most of the changes are in interface_handlers.c, which was renamed from
interface_ops.c, to convert operators to the UI handler. UI code notes:
* uiBeginBlock/uiEndBlock/uiFreeBlocks now takes a context argument, this is
  required to properly cancel things like timers or tooltips when the region
  gets removed.
* UI_add_region_handlers will add the region level UI handlers, to be used
  when adding keymap handlers etc. This replaces the UI keymap.
* When the UI code starts a modal interaction (number sliding, text editing,
  opening a menu, ..), it will add an UI handler at the window level which
  will block events.
Windowmanager changes:
* Added an UI handler next to the existing keymap and operator modal handlers.
  It has an event handling and remove callback, and like operator modal handlers
  will remember the area and region if it is registered at the window level.
* Removed the MESSAGE event.
* Operator cancel and UI handler remove callbacks now get the
  window/area/region restored in the context, like the operator modal and UI
  handler event callbacks.
* Regions now receive MOUSEMOVE events for the mouse going outside of the
  region. This was already happening for areas, but UI buttons are at the region
  level so we need it there.
Issues:
* Tooltips and menus stay open when switching to another window, and button
  highlight doesn't work without moving the mouse first when Blender starts up.
  I tried using some events like Q_FIRSTTIME, WINTHAW, but those don't seem to
  arrive..
* Timeline header buttons seem to be moving one pixel or so sometimes when
  interacting with them.
* Seems not due to this commit, but UI and keymap handlers are leaking. It
  seems that handlers are being added to regions in all screens, also in regions
  of areas that are not visible, but these handlers are not removed. Probably
  there should only be handlers in visible regions?

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.

* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.

merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

UI: don't use operators anymore for handling user interface events, but rather
a special UI handler which makes the code clearer. This UI handler is attached
to the region along with other handlers, and also gets a callback when all
handlers for the region are removed to ensure things are properly cleaned up.
This should fix XXX's in the UI code related to events and context switching.
Most of the changes are in interface_handlers.c, which was renamed from
interface_ops.c, to convert operators to the UI handler. UI code notes:
* uiBeginBlock/uiEndBlock/uiFreeBlocks now takes a context argument, this is
  required to properly cancel things like timers or tooltips when the region
  gets removed.
* UI_add_region_handlers will add the region level UI handlers, to be used
  when adding keymap handlers etc. This replaces the UI keymap.
* When the UI code starts a modal interaction (number sliding, text editing,
  opening a menu, ..), it will add an UI handler at the window level which
  will block events.
Windowmanager changes:
* Added an UI handler next to the existing keymap and operator modal handlers.
  It has an event handling and remove callback, and like operator modal handlers
  will remember the area and region if it is registered at the window level.
* Removed the MESSAGE event.
* Operator cancel and UI handler remove callbacks now get the
  window/area/region restored in the context, like the operator modal and UI
  handler event callbacks.
* Regions now receive MOUSEMOVE events for the mouse going outside of the
  region. This was already happening for areas, but UI buttons are at the region
  level so we need it there.
Issues:
* Tooltips and menus stay open when switching to another window, and button
  highlight doesn't work without moving the mouse first when Blender starts up.
  I tried using some events like Q_FIRSTTIME, WINTHAW, but those don't seem to
  arrive..
* Timeline header buttons seem to be moving one pixel or so sometimes when
  interacting with them.
* Seems not due to this commit, but UI and keymap handlers are leaking. It
  seems that handlers are being added to regions in all screens, also in regions
  of areas that are not visible, but these handlers are not removed. Probably
  there should only be handlers in visible regions?

												Drag and drop 2.5 integration! Finally, slashdot regulars can use
Blender too now! :)
** Drag works as follows:
- drag-able items are defined by the standard interface ui toolkit
- each button can get this feature, via uiButSetDragXXX(but, ...).
  There are calls to define drag-able images, ID blocks, RNA paths, 
  file paths, and so on. By default you drag an icon, exceptionally 
  an ImBuf
- Drag items are registered centrally in the WM, it allows more drag 
  items simultaneous too, but not implemented
** Drop works as follows:
- On mouse release, and if drag items exist in the WM, it converts 
  the mouse event to an EVT_DROP type. This event then gets the full 
  drag info as customdata
- drop regions are defined with WM_dropbox_add(), similar to keymaps 
  you can make a "drop map" this way, which become 'drop map handlers' 
  in the queues.
- next to that the UI kit handles some common button types (like 
  accepting ID or names) to be catching a drop event too.
- Every "drop box" has two callbacks:
  - poll() = check if the event drag data is relevant for this box
  - copy() = fill in custom properties in the dropbox to initialize 
    an operator
- The dropbox handler then calls its standard Operator with its 
  dropbox properties.
** Currently implemented
Drag items:
- ID icons in browse buttons
- ID icons in context menu of properties region
- ID icons in outliner and rna viewer
- FileBrowser icons
- FileBrowser preview images
Drag-able icons are subtly visualized by making them brighter a bit 
on mouse-over. In case the icon is a button or UI element too (most 
cases), the drag-able feature will make the item react to 
mouse-release instead of mouse-press. 
Drop options:
- UI buttons: ID and text buttons (paste name)
- View3d: Object ID drop copies object
- View3d: Material ID drop assigns to object under cursor
- View3d: Image ID drop assigns to object UV texture under cursor
- Sequencer: Path drop will add either Image or Movie strip
- Image window: Path drop will open image
** Drag and drop Notes:
- Dropping into another Blender window (from same application) works 
too. I've added code that passes on mousemoves and clicks to other 
windows, without activating them though. This does make using multi-window
Blender a bit friendler.
- Dropping a file path to an image, is not the same as dropping an 
Image ID... keep this in mind. Sequencer for example wants paths to 
be dropped,  textures in 3d window wants an Image ID.
- Although drop boxes could be defined via Python, I suggest they're 
part of the UI and editor design (= how we want an editor to work), and 
not default offered configurable like keymaps. 
- At the moment only one item can be dragged at a time. This is for 
several reasons.... For one, Blender doesn't have a well defined 
uniform way to define "what is selected" (files, outliner items, etc). 
Secondly there's potential conflicts on what todo when you drop mixed 
drag sets on spots. All undefined stuff... nice for later.
- Example to bypass the above: a collection of images that form a strip, 
should be represented in filewindow as a single sequence anyway. 
This then will fit well and gets handled neatly by design.
- Another option to check is to allow multiple options per drop... it 
could show the operator as a sort of menu, allowing arrow or scrollwheel 
to choose. For time being I'd prefer to try to design a singular drop 
though, just offer only one drop action per data type on given spots.
- What does work already, but a tad slow, is to use a function that 
detects an object (type) under cursor, so a drag item's option can be 
further refined (like drop object on object = parent). (disabled)
** More notes
- Added saving for Region layouts (like split points for toolbar)
- Label buttons now handle mouse over
- File list: added full path entry for drop feature.
- Filesel bugfix: wm_operator_exec() got called there and fully handled, 
while WM event code tried same. Added new OPERATOR_HANDLED flag for this. 
Maybe python needs it too?
- Cocoa: added window move event, so multi-win setups work OK (didnt save).
- Interface_handlers.c: removed win->active
- Severe area copy bug: area handlers were not set to NULL
- Filesel bugfix: next/prev folder list was not copied on area copies
** Leftover todos
- Cocoa windows seem to hang on cases still... needs check
- Cocoa 'draw overlap' swap doesn't work
- Cocoa window loses focus permanently on using Spotlight
  (for these reasons, makefile building has Carbon as default atm)
- ListView templates in UI cannot become dragged yet, needs review... 
it consists of two overlapping UI elements, preventing handling icon clicks.
- There's already Ghost library code to handle dropping from OS 
into Blender window. I've noticed this code is unfinished for Macs, but 
seems to be complete for Windows. Needs test... currently, an external 
drop event will print in console when succesfully delivered to Blender's WM.

Blender too now! :)
** Drag works as follows:
- drag-able items are defined by the standard interface ui toolkit
- each button can get this feature, via uiButSetDragXXX(but, ...).
  There are calls to define drag-able images, ID blocks, RNA paths, 
  file paths, and so on. By default you drag an icon, exceptionally 
  an ImBuf
- Drag items are registered centrally in the WM, it allows more drag 
  items simultaneous too, but not implemented
** Drop works as follows:
- On mouse release, and if drag items exist in the WM, it converts 
  the mouse event to an EVT_DROP type. This event then gets the full 
  drag info as customdata
- drop regions are defined with WM_dropbox_add(), similar to keymaps 
  you can make a "drop map" this way, which become 'drop map handlers' 
  in the queues.
- next to that the UI kit handles some common button types (like 
  accepting ID or names) to be catching a drop event too.
- Every "drop box" has two callbacks:
  - poll() = check if the event drag data is relevant for this box
  - copy() = fill in custom properties in the dropbox to initialize 
    an operator
- The dropbox handler then calls its standard Operator with its 
  dropbox properties.
** Currently implemented
Drag items:
- ID icons in browse buttons
- ID icons in context menu of properties region
- ID icons in outliner and rna viewer

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:

												Drag and drop 2.5 integration! Finally, slashdot regulars can use
Blender too now! :)
** Drag works as follows:
- drag-able items are defined by the standard interface ui toolkit
- each button can get this feature, via uiButSetDragXXX(but, ...).
  There are calls to define drag-able images, ID blocks, RNA paths, 
  file paths, and so on. By default you drag an icon, exceptionally 
  an ImBuf
- Drag items are registered centrally in the WM, it allows more drag 
  items simultaneous too, but not implemented
** Drop works as follows:
- On mouse release, and if drag items exist in the WM, it converts 
  the mouse event to an EVT_DROP type. This event then gets the full 
  drag info as customdata
- drop regions are defined with WM_dropbox_add(), similar to keymaps 
  you can make a "drop map" this way, which become 'drop map handlers' 
  in the queues.
- next to that the UI kit handles some common button types (like 
  accepting ID or names) to be catching a drop event too.
- Every "drop box" has two callbacks:
  - poll() = check if the event drag data is relevant for this box
  - copy() = fill in custom properties in the dropbox to initialize 
    an operator
- The dropbox handler then calls its standard Operator with its 
  dropbox properties.
** Currently implemented
Drag items:
- ID icons in browse buttons
- ID icons in context menu of properties region
- ID icons in outliner and rna viewer
- FileBrowser icons
- FileBrowser preview images
Drag-able icons are subtly visualized by making them brighter a bit 
on mouse-over. In case the icon is a button or UI element too (most 
cases), the drag-able feature will make the item react to 
mouse-release instead of mouse-press. 
Drop options:
- UI buttons: ID and text buttons (paste name)
- View3d: Object ID drop copies object
- View3d: Material ID drop assigns to object under cursor
- View3d: Image ID drop assigns to object UV texture under cursor
- Sequencer: Path drop will add either Image or Movie strip
- Image window: Path drop will open image
** Drag and drop Notes:
- Dropping into another Blender window (from same application) works 
too. I've added code that passes on mousemoves and clicks to other 
windows, without activating them though. This does make using multi-window
Blender a bit friendler.
- Dropping a file path to an image, is not the same as dropping an 
Image ID... keep this in mind. Sequencer for example wants paths to 
be dropped,  textures in 3d window wants an Image ID.
- Although drop boxes could be defined via Python, I suggest they're 
part of the UI and editor design (= how we want an editor to work), and 
not default offered configurable like keymaps. 
- At the moment only one item can be dragged at a time. This is for 
several reasons.... For one, Blender doesn't have a well defined 
uniform way to define "what is selected" (files, outliner items, etc). 
Secondly there's potential conflicts on what todo when you drop mixed 
drag sets on spots. All undefined stuff... nice for later.
- Example to bypass the above: a collection of images that form a strip, 
should be represented in filewindow as a single sequence anyway. 
This then will fit well and gets handled neatly by design.
- Another option to check is to allow multiple options per drop... it 
could show the operator as a sort of menu, allowing arrow or scrollwheel 
to choose. For time being I'd prefer to try to design a singular drop 
though, just offer only one drop action per data type on given spots.
- What does work already, but a tad slow, is to use a function that 
detects an object (type) under cursor, so a drag item's option can be 
further refined (like drop object on object = parent). (disabled)
** More notes
- Added saving for Region layouts (like split points for toolbar)
- Label buttons now handle mouse over
- File list: added full path entry for drop feature.
- Filesel bugfix: wm_operator_exec() got called there and fully handled, 
while WM event code tried same. Added new OPERATOR_HANDLED flag for this. 
Maybe python needs it too?
- Cocoa: added window move event, so multi-win setups work OK (didnt save).
- Interface_handlers.c: removed win->active
- Severe area copy bug: area handlers were not set to NULL
- Filesel bugfix: next/prev folder list was not copied on area copies
** Leftover todos
- Cocoa windows seem to hang on cases still... needs check
- Cocoa 'draw overlap' swap doesn't work
- Cocoa window loses focus permanently on using Spotlight
  (for these reasons, makefile building has Carbon as default atm)
- ListView templates in UI cannot become dragged yet, needs review... 
it consists of two overlapping UI elements, preventing handling icon clicks.
- There's already Ghost library code to handle dropping from OS 
into Blender window. I've noticed this code is unfinished for Macs, but 
seems to be complete for Windows. Needs test... currently, an external 
drop event will print in console when succesfully delivered to Blender's WM.

UI: don't use operators anymore for handling user interface events, but rather
a special UI handler which makes the code clearer. This UI handler is attached
to the region along with other handlers, and also gets a callback when all
handlers for the region are removed to ensure things are properly cleaned up.
This should fix XXX's in the UI code related to events and context switching.
Most of the changes are in interface_handlers.c, which was renamed from
interface_ops.c, to convert operators to the UI handler. UI code notes:
* uiBeginBlock/uiEndBlock/uiFreeBlocks now takes a context argument, this is
  required to properly cancel things like timers or tooltips when the region
  gets removed.
* UI_add_region_handlers will add the region level UI handlers, to be used
  when adding keymap handlers etc. This replaces the UI keymap.
* When the UI code starts a modal interaction (number sliding, text editing,
  opening a menu, ..), it will add an UI handler at the window level which
  will block events.
Windowmanager changes:
* Added an UI handler next to the existing keymap and operator modal handlers.
  It has an event handling and remove callback, and like operator modal handlers
  will remember the area and region if it is registered at the window level.
* Removed the MESSAGE event.
* Operator cancel and UI handler remove callbacks now get the
  window/area/region restored in the context, like the operator modal and UI
  handler event callbacks.
* Regions now receive MOUSEMOVE events for the mouse going outside of the
  region. This was already happening for areas, but UI buttons are at the region
  level so we need it there.
Issues:
* Tooltips and menus stay open when switching to another window, and button
  highlight doesn't work without moving the mouse first when Blender starts up.
  I tried using some events like Q_FIRSTTIME, WINTHAW, but those don't seem to
  arrive..
* Timeline header buttons seem to be moving one pixel or so sometimes when
  interacting with them.
* Seems not due to this commit, but UI and keymap handlers are leaking. It
  seems that handlers are being added to regions in all screens, also in regions
  of areas that are not visible, but these handlers are not removed. Probably
  there should only be handlers in visible regions?

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.

  handle. Operators may not be the best way to implement this, since there are

* The button activate operator runs as long as a button is active, and will

  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made

  the operator receives more events.

  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable

* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct

  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.

* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu

  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full

Testing:
* The header in the time space currently has some buttons to test the UI code.

* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

												UI:
* Added support for soft/hard range in the buttons code. Currently
  it works by only allowing to drag or click increment in the soft
  range, but typing a number value allows to go outside it.
  If the number is outside the soft range, the range will be extended,
  rounded to values like:
  .., 0.1, 0.2, 0.5, 1.0, 2.0, 5.0, 10.0, 20.0, 50.0, ..

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

UI: don't use operators anymore for handling user interface events, but rather
a special UI handler which makes the code clearer. This UI handler is attached
to the region along with other handlers, and also gets a callback when all
handlers for the region are removed to ensure things are properly cleaned up.
This should fix XXX's in the UI code related to events and context switching.
Most of the changes are in interface_handlers.c, which was renamed from
interface_ops.c, to convert operators to the UI handler. UI code notes:
* uiBeginBlock/uiEndBlock/uiFreeBlocks now takes a context argument, this is
  required to properly cancel things like timers or tooltips when the region
  gets removed.
* UI_add_region_handlers will add the region level UI handlers, to be used
  when adding keymap handlers etc. This replaces the UI keymap.
* When the UI code starts a modal interaction (number sliding, text editing,
  opening a menu, ..), it will add an UI handler at the window level which
  will block events.
Windowmanager changes:
* Added an UI handler next to the existing keymap and operator modal handlers.
  It has an event handling and remove callback, and like operator modal handlers
  will remember the area and region if it is registered at the window level.
* Removed the MESSAGE event.
* Operator cancel and UI handler remove callbacks now get the
  window/area/region restored in the context, like the operator modal and UI
  handler event callbacks.
* Regions now receive MOUSEMOVE events for the mouse going outside of the
  region. This was already happening for areas, but UI buttons are at the region
  level so we need it there.
Issues:
* Tooltips and menus stay open when switching to another window, and button
  highlight doesn't work without moving the mouse first when Blender starts up.
  I tried using some events like Q_FIRSTTIME, WINTHAW, but those don't seem to
  arrive..
* Timeline header buttons seem to be moving one pixel or so sometimes when
  interacting with them.
* Seems not due to this commit, but UI and keymap handlers are leaking. It
  seems that handlers are being added to regions in all screens, also in regions
  of areas that are not visible, but these handlers are not removed. Probably
  there should only be handlers in visible regions?

  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code

  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.

* interface_regions: this is a part of interface.c, split off, contains code to

  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.

  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.

  If the number is outside the soft range, the range will be extended,
  rounded to values like:

  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.

UI: don't use operators anymore for handling user interface events, but rather
a special UI handler which makes the code clearer. This UI handler is attached
to the region along with other handlers, and also gets a callback when all
handlers for the region are removed to ensure things are properly cleaned up.
This should fix XXX's in the UI code related to events and context switching.
Most of the changes are in interface_handlers.c, which was renamed from
interface_ops.c, to convert operators to the UI handler. UI code notes:
* uiBeginBlock/uiEndBlock/uiFreeBlocks now takes a context argument, this is
  required to properly cancel things like timers or tooltips when the region
  gets removed.
* UI_add_region_handlers will add the region level UI handlers, to be used
  when adding keymap handlers etc. This replaces the UI keymap.
* When the UI code starts a modal interaction (number sliding, text editing,
  opening a menu, ..), it will add an UI handler at the window level which
  will block events.
Windowmanager changes:
* Added an UI handler next to the existing keymap and operator modal handlers.
  It has an event handling and remove callback, and like operator modal handlers
  will remember the area and region if it is registered at the window level.
* Removed the MESSAGE event.
* Operator cancel and UI handler remove callbacks now get the
  window/area/region restored in the context, like the operator modal and UI
  handler event callbacks.
* Regions now receive MOUSEMOVE events for the mouse going outside of the
  region. This was already happening for areas, but UI buttons are at the region
  level so we need it there.
Issues:
* Tooltips and menus stay open when switching to another window, and button
  highlight doesn't work without moving the mouse first when Blender starts up.
  I tried using some events like Q_FIRSTTIME, WINTHAW, but those don't seem to
  arrive..
* Timeline header buttons seem to be moving one pixel or so sometimes when
  interacting with them.
* Seems not due to this commit, but UI and keymap handlers are leaking. It
  seems that handlers are being added to regions in all screens, also in regions
  of areas that are not visible, but these handlers are not removed. Probably
  there should only be handlers in visible regions?

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.

Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to

  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it

  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the

  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window

* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window

UI: don't use operators anymore for handling user interface events, but rather
a special UI handler which makes the code clearer. This UI handler is attached
to the region along with other handlers, and also gets a callback when all
handlers for the region are removed to ensure things are properly cleaned up.
This should fix XXX's in the UI code related to events and context switching.
Most of the changes are in interface_handlers.c, which was renamed from
interface_ops.c, to convert operators to the UI handler. UI code notes:
* uiBeginBlock/uiEndBlock/uiFreeBlocks now takes a context argument, this is
  required to properly cancel things like timers or tooltips when the region
  gets removed.
* UI_add_region_handlers will add the region level UI handlers, to be used
  when adding keymap handlers etc. This replaces the UI keymap.
* When the UI code starts a modal interaction (number sliding, text editing,
  opening a menu, ..), it will add an UI handler at the window level which
  will block events.
Windowmanager changes:
* Added an UI handler next to the existing keymap and operator modal handlers.
  It has an event handling and remove callback, and like operator modal handlers
  will remember the area and region if it is registered at the window level.
* Removed the MESSAGE event.
* Operator cancel and UI handler remove callbacks now get the
  window/area/region restored in the context, like the operator modal and UI
  handler event callbacks.
* Regions now receive MOUSEMOVE events for the mouse going outside of the
  region. This was already happening for areas, but UI buttons are at the region
  level so we need it there.
Issues:
* Tooltips and menus stay open when switching to another window, and button
  highlight doesn't work without moving the mouse first when Blender starts up.
  I tried using some events like Q_FIRSTTIME, WINTHAW, but those don't seem to
  arrive..
* Timeline header buttons seem to be moving one pixel or so sometimes when
  interacting with them.
* Seems not due to this commit, but UI and keymap handlers are leaking. It
  seems that handlers are being added to regions in all screens, also in regions
  of areas that are not visible, but these handlers are not removed. Probably
  there should only be handlers in visible regions?

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

UI: don't use operators anymore for handling user interface events, but rather
a special UI handler which makes the code clearer. This UI handler is attached
to the region along with other handlers, and also gets a callback when all
handlers for the region are removed to ensure things are properly cleaned up.
This should fix XXX's in the UI code related to events and context switching.
Most of the changes are in interface_handlers.c, which was renamed from
interface_ops.c, to convert operators to the UI handler. UI code notes:
* uiBeginBlock/uiEndBlock/uiFreeBlocks now takes a context argument, this is
  required to properly cancel things like timers or tooltips when the region
  gets removed.
* UI_add_region_handlers will add the region level UI handlers, to be used
  when adding keymap handlers etc. This replaces the UI keymap.
* When the UI code starts a modal interaction (number sliding, text editing,
  opening a menu, ..), it will add an UI handler at the window level which
  will block events.
Windowmanager changes:
* Added an UI handler next to the existing keymap and operator modal handlers.
  It has an event handling and remove callback, and like operator modal handlers
  will remember the area and region if it is registered at the window level.
* Removed the MESSAGE event.
* Operator cancel and UI handler remove callbacks now get the
  window/area/region restored in the context, like the operator modal and UI
  handler event callbacks.
* Regions now receive MOUSEMOVE events for the mouse going outside of the
  region. This was already happening for areas, but UI buttons are at the region
  level so we need it there.
Issues:
* Tooltips and menus stay open when switching to another window, and button
  highlight doesn't work without moving the mouse first when Blender starts up.
  I tried using some events like Q_FIRSTTIME, WINTHAW, but those don't seem to
  arrive..
* Timeline header buttons seem to be moving one pixel or so sometimes when
  interacting with them.
* Seems not due to this commit, but UI and keymap handlers are leaking. It
  seems that handlers are being added to regions in all screens, also in regions
  of areas that are not visible, but these handlers are not removed. Probably
  there should only be handlers in visible regions?

												Drag and drop 2.5 integration! Finally, slashdot regulars can use
Blender too now! :)
** Drag works as follows:
- drag-able items are defined by the standard interface ui toolkit
- each button can get this feature, via uiButSetDragXXX(but, ...).
  There are calls to define drag-able images, ID blocks, RNA paths, 
  file paths, and so on. By default you drag an icon, exceptionally 
  an ImBuf
- Drag items are registered centrally in the WM, it allows more drag 
  items simultaneous too, but not implemented
** Drop works as follows:
- On mouse release, and if drag items exist in the WM, it converts 
  the mouse event to an EVT_DROP type. This event then gets the full 
  drag info as customdata
- drop regions are defined with WM_dropbox_add(), similar to keymaps 
  you can make a "drop map" this way, which become 'drop map handlers' 
  in the queues.
- next to that the UI kit handles some common button types (like 
  accepting ID or names) to be catching a drop event too.
- Every "drop box" has two callbacks:
  - poll() = check if the event drag data is relevant for this box
  - copy() = fill in custom properties in the dropbox to initialize 
    an operator
- The dropbox handler then calls its standard Operator with its 
  dropbox properties.
** Currently implemented
Drag items:
- ID icons in browse buttons
- ID icons in context menu of properties region
- ID icons in outliner and rna viewer
- FileBrowser icons
- FileBrowser preview images
Drag-able icons are subtly visualized by making them brighter a bit 
on mouse-over. In case the icon is a button or UI element too (most 
cases), the drag-able feature will make the item react to 
mouse-release instead of mouse-press. 
Drop options:
- UI buttons: ID and text buttons (paste name)
- View3d: Object ID drop copies object
- View3d: Material ID drop assigns to object under cursor
- View3d: Image ID drop assigns to object UV texture under cursor
- Sequencer: Path drop will add either Image or Movie strip
- Image window: Path drop will open image
** Drag and drop Notes:
- Dropping into another Blender window (from same application) works 
too. I've added code that passes on mousemoves and clicks to other 
windows, without activating them though. This does make using multi-window
Blender a bit friendler.
- Dropping a file path to an image, is not the same as dropping an 
Image ID... keep this in mind. Sequencer for example wants paths to 
be dropped,  textures in 3d window wants an Image ID.
- Although drop boxes could be defined via Python, I suggest they're 
part of the UI and editor design (= how we want an editor to work), and 
not default offered configurable like keymaps. 
- At the moment only one item can be dragged at a time. This is for 
several reasons.... For one, Blender doesn't have a well defined 
uniform way to define "what is selected" (files, outliner items, etc). 
Secondly there's potential conflicts on what todo when you drop mixed 
drag sets on spots. All undefined stuff... nice for later.
- Example to bypass the above: a collection of images that form a strip, 
should be represented in filewindow as a single sequence anyway. 
This then will fit well and gets handled neatly by design.
- Another option to check is to allow multiple options per drop... it 
could show the operator as a sort of menu, allowing arrow or scrollwheel 
to choose. For time being I'd prefer to try to design a singular drop 
though, just offer only one drop action per data type on given spots.
- What does work already, but a tad slow, is to use a function that 
detects an object (type) under cursor, so a drag item's option can be 
further refined (like drop object on object = parent). (disabled)
** More notes
- Added saving for Region layouts (like split points for toolbar)
- Label buttons now handle mouse over
- File list: added full path entry for drop feature.
- Filesel bugfix: wm_operator_exec() got called there and fully handled, 
while WM event code tried same. Added new OPERATOR_HANDLED flag for this. 
Maybe python needs it too?
- Cocoa: added window move event, so multi-win setups work OK (didnt save).
- Interface_handlers.c: removed win->active
- Severe area copy bug: area handlers were not set to NULL
- Filesel bugfix: next/prev folder list was not copied on area copies
** Leftover todos
- Cocoa windows seem to hang on cases still... needs check
- Cocoa 'draw overlap' swap doesn't work
- Cocoa window loses focus permanently on using Spotlight
  (for these reasons, makefile building has Carbon as default atm)
- ListView templates in UI cannot become dragged yet, needs review... 
it consists of two overlapping UI elements, preventing handling icon clicks.
- There's already Ghost library code to handle dropping from OS 
into Blender window. I've noticed this code is unfinished for Macs, but 
seems to be complete for Windows. Needs test... currently, an external 
drop event will print in console when succesfully delivered to Blender's WM.

UI: don't use operators anymore for handling user interface events, but rather
a special UI handler which makes the code clearer. This UI handler is attached
to the region along with other handlers, and also gets a callback when all
handlers for the region are removed to ensure things are properly cleaned up.
This should fix XXX's in the UI code related to events and context switching.
Most of the changes are in interface_handlers.c, which was renamed from
interface_ops.c, to convert operators to the UI handler. UI code notes:
* uiBeginBlock/uiEndBlock/uiFreeBlocks now takes a context argument, this is
  required to properly cancel things like timers or tooltips when the region
  gets removed.
* UI_add_region_handlers will add the region level UI handlers, to be used
  when adding keymap handlers etc. This replaces the UI keymap.
* When the UI code starts a modal interaction (number sliding, text editing,
  opening a menu, ..), it will add an UI handler at the window level which
  will block events.
Windowmanager changes:
* Added an UI handler next to the existing keymap and operator modal handlers.
  It has an event handling and remove callback, and like operator modal handlers
  will remember the area and region if it is registered at the window level.
* Removed the MESSAGE event.
* Operator cancel and UI handler remove callbacks now get the
  window/area/region restored in the context, like the operator modal and UI
  handler event callbacks.
* Regions now receive MOUSEMOVE events for the mouse going outside of the
  region. This was already happening for areas, but UI buttons are at the region
  level so we need it there.
Issues:
* Tooltips and menus stay open when switching to another window, and button
  highlight doesn't work without moving the mouse first when Blender starts up.
  I tried using some events like Q_FIRSTTIME, WINTHAW, but those don't seem to
  arrive..
* Timeline header buttons seem to be moving one pixel or so sometimes when
  interacting with them.
* Seems not due to this commit, but UI and keymap handlers are leaking. It
  seems that handlers are being added to regions in all screens, also in regions
  of areas that are not visible, but these handlers are not removed. Probably
  there should only be handlers in visible regions?

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

												Drag and drop 2.5 integration! Finally, slashdot regulars can use
Blender too now! :)
** Drag works as follows:
- drag-able items are defined by the standard interface ui toolkit
- each button can get this feature, via uiButSetDragXXX(but, ...).
  There are calls to define drag-able images, ID blocks, RNA paths, 
  file paths, and so on. By default you drag an icon, exceptionally 
  an ImBuf
- Drag items are registered centrally in the WM, it allows more drag 
  items simultaneous too, but not implemented
** Drop works as follows:
- On mouse release, and if drag items exist in the WM, it converts 
  the mouse event to an EVT_DROP type. This event then gets the full 
  drag info as customdata
- drop regions are defined with WM_dropbox_add(), similar to keymaps 
  you can make a "drop map" this way, which become 'drop map handlers' 
  in the queues.
- next to that the UI kit handles some common button types (like 
  accepting ID or names) to be catching a drop event too.
- Every "drop box" has two callbacks:
  - poll() = check if the event drag data is relevant for this box
  - copy() = fill in custom properties in the dropbox to initialize 
    an operator
- The dropbox handler then calls its standard Operator with its 
  dropbox properties.
** Currently implemented
Drag items:
- ID icons in browse buttons
- ID icons in context menu of properties region
- ID icons in outliner and rna viewer
- FileBrowser icons
- FileBrowser preview images
Drag-able icons are subtly visualized by making them brighter a bit 
on mouse-over. In case the icon is a button or UI element too (most 
cases), the drag-able feature will make the item react to 
mouse-release instead of mouse-press. 
Drop options:
- UI buttons: ID and text buttons (paste name)
- View3d: Object ID drop copies object
- View3d: Material ID drop assigns to object under cursor
- View3d: Image ID drop assigns to object UV texture under cursor
- Sequencer: Path drop will add either Image or Movie strip
- Image window: Path drop will open image
** Drag and drop Notes:
- Dropping into another Blender window (from same application) works 
too. I've added code that passes on mousemoves and clicks to other 
windows, without activating them though. This does make using multi-window
Blender a bit friendler.
- Dropping a file path to an image, is not the same as dropping an 
Image ID... keep this in mind. Sequencer for example wants paths to 
be dropped,  textures in 3d window wants an Image ID.
- Although drop boxes could be defined via Python, I suggest they're 
part of the UI and editor design (= how we want an editor to work), and 
not default offered configurable like keymaps. 
- At the moment only one item can be dragged at a time. This is for 
several reasons.... For one, Blender doesn't have a well defined 
uniform way to define "what is selected" (files, outliner items, etc). 
Secondly there's potential conflicts on what todo when you drop mixed 
drag sets on spots. All undefined stuff... nice for later.
- Example to bypass the above: a collection of images that form a strip, 
should be represented in filewindow as a single sequence anyway. 
This then will fit well and gets handled neatly by design.
- Another option to check is to allow multiple options per drop... it 
could show the operator as a sort of menu, allowing arrow or scrollwheel 
to choose. For time being I'd prefer to try to design a singular drop 
though, just offer only one drop action per data type on given spots.
- What does work already, but a tad slow, is to use a function that 
detects an object (type) under cursor, so a drag item's option can be 
further refined (like drop object on object = parent). (disabled)
** More notes
- Added saving for Region layouts (like split points for toolbar)
- Label buttons now handle mouse over
- File list: added full path entry for drop feature.
- Filesel bugfix: wm_operator_exec() got called there and fully handled, 
while WM event code tried same. Added new OPERATOR_HANDLED flag for this. 
Maybe python needs it too?
- Cocoa: added window move event, so multi-win setups work OK (didnt save).
- Interface_handlers.c: removed win->active
- Severe area copy bug: area handlers were not set to NULL
- Filesel bugfix: next/prev folder list was not copied on area copies
** Leftover todos
- Cocoa windows seem to hang on cases still... needs check
- Cocoa 'draw overlap' swap doesn't work
- Cocoa window loses focus permanently on using Spotlight
  (for these reasons, makefile building has Carbon as default atm)
- ListView templates in UI cannot become dragged yet, needs review... 
it consists of two overlapping UI elements, preventing handling icon clicks.
- There's already Ghost library code to handle dropping from OS 
into Blender window. I've noticed this code is unfinished for Macs, but 
seems to be complete for Windows. Needs test... currently, an external 
drop event will print in console when succesfully delivered to Blender's WM.

UI: don't use operators anymore for handling user interface events, but rather
a special UI handler which makes the code clearer. This UI handler is attached
to the region along with other handlers, and also gets a callback when all
handlers for the region are removed to ensure things are properly cleaned up.
This should fix XXX's in the UI code related to events and context switching.
Most of the changes are in interface_handlers.c, which was renamed from
interface_ops.c, to convert operators to the UI handler. UI code notes:
* uiBeginBlock/uiEndBlock/uiFreeBlocks now takes a context argument, this is
  required to properly cancel things like timers or tooltips when the region
  gets removed.
* UI_add_region_handlers will add the region level UI handlers, to be used
  when adding keymap handlers etc. This replaces the UI keymap.
* When the UI code starts a modal interaction (number sliding, text editing,
  opening a menu, ..), it will add an UI handler at the window level which
  will block events.
Windowmanager changes:
* Added an UI handler next to the existing keymap and operator modal handlers.
  It has an event handling and remove callback, and like operator modal handlers
  will remember the area and region if it is registered at the window level.
* Removed the MESSAGE event.
* Operator cancel and UI handler remove callbacks now get the
  window/area/region restored in the context, like the operator modal and UI
  handler event callbacks.
* Regions now receive MOUSEMOVE events for the mouse going outside of the
  region. This was already happening for areas, but UI buttons are at the region
  level so we need it there.
Issues:
* Tooltips and menus stay open when switching to another window, and button
  highlight doesn't work without moving the mouse first when Blender starts up.
  I tried using some events like Q_FIRSTTIME, WINTHAW, but those don't seem to
  arrive..
* Timeline header buttons seem to be moving one pixel or so sometimes when
  interacting with them.
* Seems not due to this commit, but UI and keymap handlers are leaking. It
  seems that handlers are being added to regions in all screens, also in regions
  of areas that are not visible, but these handlers are not removed. Probably
  there should only be handlers in visible regions?

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

												Drag and drop 2.5 integration! Finally, slashdot regulars can use
Blender too now! :)
** Drag works as follows:
- drag-able items are defined by the standard interface ui toolkit
- each button can get this feature, via uiButSetDragXXX(but, ...).
  There are calls to define drag-able images, ID blocks, RNA paths, 
  file paths, and so on. By default you drag an icon, exceptionally 
  an ImBuf
- Drag items are registered centrally in the WM, it allows more drag 
  items simultaneous too, but not implemented
** Drop works as follows:
- On mouse release, and if drag items exist in the WM, it converts 
  the mouse event to an EVT_DROP type. This event then gets the full 
  drag info as customdata
- drop regions are defined with WM_dropbox_add(), similar to keymaps 
  you can make a "drop map" this way, which become 'drop map handlers' 
  in the queues.
- next to that the UI kit handles some common button types (like 
  accepting ID or names) to be catching a drop event too.
- Every "drop box" has two callbacks:
  - poll() = check if the event drag data is relevant for this box
  - copy() = fill in custom properties in the dropbox to initialize 
    an operator
- The dropbox handler then calls its standard Operator with its 
  dropbox properties.
** Currently implemented
Drag items:
- ID icons in browse buttons
- ID icons in context menu of properties region
- ID icons in outliner and rna viewer
- FileBrowser icons
- FileBrowser preview images
Drag-able icons are subtly visualized by making them brighter a bit 
on mouse-over. In case the icon is a button or UI element too (most 
cases), the drag-able feature will make the item react to 
mouse-release instead of mouse-press. 
Drop options:
- UI buttons: ID and text buttons (paste name)
- View3d: Object ID drop copies object
- View3d: Material ID drop assigns to object under cursor
- View3d: Image ID drop assigns to object UV texture under cursor
- Sequencer: Path drop will add either Image or Movie strip
- Image window: Path drop will open image
** Drag and drop Notes:
- Dropping into another Blender window (from same application) works 
too. I've added code that passes on mousemoves and clicks to other 
windows, without activating them though. This does make using multi-window
Blender a bit friendler.
- Dropping a file path to an image, is not the same as dropping an 
Image ID... keep this in mind. Sequencer for example wants paths to 
be dropped,  textures in 3d window wants an Image ID.
- Although drop boxes could be defined via Python, I suggest they're 
part of the UI and editor design (= how we want an editor to work), and 
not default offered configurable like keymaps. 
- At the moment only one item can be dragged at a time. This is for 
several reasons.... For one, Blender doesn't have a well defined 
uniform way to define "what is selected" (files, outliner items, etc). 
Secondly there's potential conflicts on what todo when you drop mixed 
drag sets on spots. All undefined stuff... nice for later.
- Example to bypass the above: a collection of images that form a strip, 
should be represented in filewindow as a single sequence anyway. 
This then will fit well and gets handled neatly by design.
- Another option to check is to allow multiple options per drop... it 
could show the operator as a sort of menu, allowing arrow or scrollwheel 
to choose. For time being I'd prefer to try to design a singular drop 
though, just offer only one drop action per data type on given spots.
- What does work already, but a tad slow, is to use a function that 
detects an object (type) under cursor, so a drag item's option can be 
further refined (like drop object on object = parent). (disabled)
** More notes
- Added saving for Region layouts (like split points for toolbar)
- Label buttons now handle mouse over
- File list: added full path entry for drop feature.
- Filesel bugfix: wm_operator_exec() got called there and fully handled, 
while WM event code tried same. Added new OPERATOR_HANDLED flag for this. 
Maybe python needs it too?
- Cocoa: added window move event, so multi-win setups work OK (didnt save).
- Interface_handlers.c: removed win->active
- Severe area copy bug: area handlers were not set to NULL
- Filesel bugfix: next/prev folder list was not copied on area copies
** Leftover todos
- Cocoa windows seem to hang on cases still... needs check
- Cocoa 'draw overlap' swap doesn't work
- Cocoa window loses focus permanently on using Spotlight
  (for these reasons, makefile building has Carbon as default atm)
- ListView templates in UI cannot become dragged yet, needs review... 
it consists of two overlapping UI elements, preventing handling icon clicks.
- There's already Ghost library code to handle dropping from OS 
into Blender window. I've noticed this code is unfinished for Macs, but 
seems to be complete for Windows. Needs test... currently, an external 
drop event will print in console when succesfully delivered to Blender's WM.

- Example to bypass the above: a collection of images that form a strip, 
should be represented in filewindow as a single sequence anyway. 
This then will fit well and gets handled neatly by design.
- Another option to check is to allow multiple options per drop... it 
could show the operator as a sort of menu, allowing arrow or scrollwheel 
to choose. For time being I'd prefer to try to design a singular drop 
though, just offer only one drop action per data type on given spots.
- What does work already, but a tad slow, is to use a function that 
detects an object (type) under cursor, so a drag item's option can be 
further refined (like drop object on object = parent). (disabled)
** More notes
- Added saving for Region layouts (like split points for toolbar)
- Label buttons now handle mouse over
- File list: added full path entry for drop feature.
- Filesel bugfix: wm_operator_exec() got called there and fully handled, 
while WM event code tried same. Added new OPERATOR_HANDLED flag for this. 
Maybe python needs it too?
- Cocoa: added window move event, so multi-win setups work OK (didnt save).
- Interface_handlers.c: removed win->active
- Severe area copy bug: area handlers were not set to NULL
- Filesel bugfix: next/prev folder list was not copied on area copies
** Leftover todos
- Cocoa windows seem to hang on cases still... needs check
- Cocoa 'draw overlap' swap doesn't work
- Cocoa window loses focus permanently on using Spotlight
  (for these reasons, makefile building has Carbon as default atm)
- ListView templates in UI cannot become dragged yet, needs review... 
it consists of two overlapping UI elements, preventing handling icon clicks.
- There's already Ghost library code to handle dropping from OS 
into Blender window. I've noticed this code is unfinished for Macs, but 
seems to be complete for Windows. Needs test... currently, an external 
drop event will print in console when succesfully delivered to Blender's WM.

												Drag and drop 2.5 integration! Finally, slashdot regulars can use
Blender too now! :)
** Drag works as follows:
- drag-able items are defined by the standard interface ui toolkit
- each button can get this feature, via uiButSetDragXXX(but, ...).
  There are calls to define drag-able images, ID blocks, RNA paths, 
  file paths, and so on. By default you drag an icon, exceptionally 
  an ImBuf
- Drag items are registered centrally in the WM, it allows more drag 
  items simultaneous too, but not implemented
** Drop works as follows:
- On mouse release, and if drag items exist in the WM, it converts 
  the mouse event to an EVT_DROP type. This event then gets the full 
  drag info as customdata
- drop regions are defined with WM_dropbox_add(), similar to keymaps 
  you can make a "drop map" this way, which become 'drop map handlers' 
  in the queues.
- next to that the UI kit handles some common button types (like 
  accepting ID or names) to be catching a drop event too.
- Every "drop box" has two callbacks:
  - poll() = check if the event drag data is relevant for this box
  - copy() = fill in custom properties in the dropbox to initialize 
    an operator
- The dropbox handler then calls its standard Operator with its 
  dropbox properties.
** Currently implemented
Drag items:
- ID icons in browse buttons
- ID icons in context menu of properties region
- ID icons in outliner and rna viewer
- FileBrowser icons
- FileBrowser preview images
Drag-able icons are subtly visualized by making them brighter a bit 
on mouse-over. In case the icon is a button or UI element too (most 
cases), the drag-able feature will make the item react to 
mouse-release instead of mouse-press. 
Drop options:
- UI buttons: ID and text buttons (paste name)
- View3d: Object ID drop copies object
- View3d: Material ID drop assigns to object under cursor
- View3d: Image ID drop assigns to object UV texture under cursor
- Sequencer: Path drop will add either Image or Movie strip
- Image window: Path drop will open image
** Drag and drop Notes:
- Dropping into another Blender window (from same application) works 
too. I've added code that passes on mousemoves and clicks to other 
windows, without activating them though. This does make using multi-window
Blender a bit friendler.
- Dropping a file path to an image, is not the same as dropping an 
Image ID... keep this in mind. Sequencer for example wants paths to 
be dropped,  textures in 3d window wants an Image ID.
- Although drop boxes could be defined via Python, I suggest they're 
part of the UI and editor design (= how we want an editor to work), and 
not default offered configurable like keymaps. 
- At the moment only one item can be dragged at a time. This is for 
several reasons.... For one, Blender doesn't have a well defined 
uniform way to define "what is selected" (files, outliner items, etc). 
Secondly there's potential conflicts on what todo when you drop mixed 
drag sets on spots. All undefined stuff... nice for later.
- Example to bypass the above: a collection of images that form a strip, 
should be represented in filewindow as a single sequence anyway. 
This then will fit well and gets handled neatly by design.
- Another option to check is to allow multiple options per drop... it 
could show the operator as a sort of menu, allowing arrow or scrollwheel

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

UI: don't use operators anymore for handling user interface events, but rather
a special UI handler which makes the code clearer. This UI handler is attached
to the region along with other handlers, and also gets a callback when all
handlers for the region are removed to ensure things are properly cleaned up.
This should fix XXX's in the UI code related to events and context switching.
Most of the changes are in interface_handlers.c, which was renamed from
interface_ops.c, to convert operators to the UI handler. UI code notes:
* uiBeginBlock/uiEndBlock/uiFreeBlocks now takes a context argument, this is
  required to properly cancel things like timers or tooltips when the region
  gets removed.
* UI_add_region_handlers will add the region level UI handlers, to be used
  when adding keymap handlers etc. This replaces the UI keymap.
* When the UI code starts a modal interaction (number sliding, text editing,
  opening a menu, ..), it will add an UI handler at the window level which
  will block events.
Windowmanager changes:
* Added an UI handler next to the existing keymap and operator modal handlers.
  It has an event handling and remove callback, and like operator modal handlers
  will remember the area and region if it is registered at the window level.
* Removed the MESSAGE event.
* Operator cancel and UI handler remove callbacks now get the
  window/area/region restored in the context, like the operator modal and UI
  handler event callbacks.
* Regions now receive MOUSEMOVE events for the mouse going outside of the
  region. This was already happening for areas, but UI buttons are at the region
  level so we need it there.
Issues:
* Tooltips and menus stay open when switching to another window, and button
  highlight doesn't work without moving the mouse first when Blender starts up.
  I tried using some events like Q_FIRSTTIME, WINTHAW, but those don't seem to
  arrive..
* Timeline header buttons seem to be moving one pixel or so sometimes when
  interacting with them.
* Seems not due to this commit, but UI and keymap handlers are leaking. It
  seems that handlers are being added to regions in all screens, also in regions
  of areas that are not visible, but these handlers are not removed. Probably
  there should only be handlers in visible regions?

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.

  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

UI: don't use operators anymore for handling user interface events, but rather
a special UI handler which makes the code clearer. This UI handler is attached
to the region along with other handlers, and also gets a callback when all
handlers for the region are removed to ensure things are properly cleaned up.
This should fix XXX's in the UI code related to events and context switching.
Most of the changes are in interface_handlers.c, which was renamed from
interface_ops.c, to convert operators to the UI handler. UI code notes:
* uiBeginBlock/uiEndBlock/uiFreeBlocks now takes a context argument, this is
  required to properly cancel things like timers or tooltips when the region
  gets removed.
* UI_add_region_handlers will add the region level UI handlers, to be used
  when adding keymap handlers etc. This replaces the UI keymap.
* When the UI code starts a modal interaction (number sliding, text editing,
  opening a menu, ..), it will add an UI handler at the window level which
  will block events.
Windowmanager changes:
* Added an UI handler next to the existing keymap and operator modal handlers.
  It has an event handling and remove callback, and like operator modal handlers
  will remember the area and region if it is registered at the window level.
* Removed the MESSAGE event.
* Operator cancel and UI handler remove callbacks now get the
  window/area/region restored in the context, like the operator modal and UI
  handler event callbacks.
* Regions now receive MOUSEMOVE events for the mouse going outside of the
  region. This was already happening for areas, but UI buttons are at the region
  level so we need it there.
Issues:
* Tooltips and menus stay open when switching to another window, and button
  highlight doesn't work without moving the mouse first when Blender starts up.
  I tried using some events like Q_FIRSTTIME, WINTHAW, but those don't seem to
  arrive..
* Timeline header buttons seem to be moving one pixel or so sometimes when
  interacting with them.
* Seems not due to this commit, but UI and keymap handlers are leaking. It
  seems that handlers are being added to regions in all screens, also in regions
  of areas that are not visible, but these handlers are not removed. Probably
  there should only be handlers in visible regions?

  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will

UI: don't use operators anymore for handling user interface events, but rather
a special UI handler which makes the code clearer. This UI handler is attached
to the region along with other handlers, and also gets a callback when all
handlers for the region are removed to ensure things are properly cleaned up.
This should fix XXX's in the UI code related to events and context switching.
Most of the changes are in interface_handlers.c, which was renamed from
interface_ops.c, to convert operators to the UI handler. UI code notes:
* uiBeginBlock/uiEndBlock/uiFreeBlocks now takes a context argument, this is
  required to properly cancel things like timers or tooltips when the region
  gets removed.
* UI_add_region_handlers will add the region level UI handlers, to be used
  when adding keymap handlers etc. This replaces the UI keymap.
* When the UI code starts a modal interaction (number sliding, text editing,
  opening a menu, ..), it will add an UI handler at the window level which
  will block events.
Windowmanager changes:
* Added an UI handler next to the existing keymap and operator modal handlers.
  It has an event handling and remove callback, and like operator modal handlers
  will remember the area and region if it is registered at the window level.
* Removed the MESSAGE event.
* Operator cancel and UI handler remove callbacks now get the
  window/area/region restored in the context, like the operator modal and UI
  handler event callbacks.
* Regions now receive MOUSEMOVE events for the mouse going outside of the
  region. This was already happening for areas, but UI buttons are at the region
  level so we need it there.
Issues:
* Tooltips and menus stay open when switching to another window, and button
  highlight doesn't work without moving the mouse first when Blender starts up.
  I tried using some events like Q_FIRSTTIME, WINTHAW, but those don't seem to
  arrive..
* Timeline header buttons seem to be moving one pixel or so sometimes when
  interacting with them.
* Seems not due to this commit, but UI and keymap handlers are leaking. It
  seems that handlers are being added to regions in all screens, also in regions
  of areas that are not visible, but these handlers are not removed. Probably
  there should only be handlers in visible regions?

* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.

  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

UI: don't use operators anymore for handling user interface events, but rather
a special UI handler which makes the code clearer. This UI handler is attached
to the region along with other handlers, and also gets a callback when all
handlers for the region are removed to ensure things are properly cleaned up.
This should fix XXX's in the UI code related to events and context switching.
Most of the changes are in interface_handlers.c, which was renamed from
interface_ops.c, to convert operators to the UI handler. UI code notes:
* uiBeginBlock/uiEndBlock/uiFreeBlocks now takes a context argument, this is
  required to properly cancel things like timers or tooltips when the region
  gets removed.
* UI_add_region_handlers will add the region level UI handlers, to be used
  when adding keymap handlers etc. This replaces the UI keymap.
* When the UI code starts a modal interaction (number sliding, text editing,
  opening a menu, ..), it will add an UI handler at the window level which
  will block events.
Windowmanager changes:
* Added an UI handler next to the existing keymap and operator modal handlers.
  It has an event handling and remove callback, and like operator modal handlers
  will remember the area and region if it is registered at the window level.
* Removed the MESSAGE event.
* Operator cancel and UI handler remove callbacks now get the
  window/area/region restored in the context, like the operator modal and UI
  handler event callbacks.
* Regions now receive MOUSEMOVE events for the mouse going outside of the
  region. This was already happening for areas, but UI buttons are at the region
  level so we need it there.
Issues:
* Tooltips and menus stay open when switching to another window, and button
  highlight doesn't work without moving the mouse first when Blender starts up.
  I tried using some events like Q_FIRSTTIME, WINTHAW, but those don't seem to
  arrive..
* Timeline header buttons seem to be moving one pixel or so sometimes when
  interacting with them.
* Seems not due to this commit, but UI and keymap handlers are leaking. It
  seems that handlers are being added to regions in all screens, also in regions
  of areas that are not visible, but these handlers are not removed. Probably
  there should only be handlers in visible regions?

* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to

												Changes to Color Management
After testing and feedback, I've decided to slightly modify the way color 
management works internally. While the previous method worked well for 
rendering, was a smaller transition and had some advantages over this
new method, it was a bit more ambiguous, and was making things difficult 
for other areas such as compositing.
This implementation now considers all color data (with only a couple of 
exceptions such as brush colors) to be stored in linear RGB color space, 
rather than sRGB as previously. This brings it in line with Nuke, which also 
operates this way, quite successfully. Color swatches, pickers, color ramp 
display are now gamma corrected to display gamma so you can see what 
you're doing, but the numbers themselves are considered linear. This 
makes understanding blending modes more clear (a 0.5 value on overlay 
will not change the result now) as well as making color swatches act more 
predictably in the compositor, however bringing over color values from 
applications like photoshop or gimp, that operate in a gamma space, 
will give identical results.
This commit will convert over existing files saved by earlier 2.5 versions to 
work generally the same, though there may be some slight differences with 
things like textures. Now that we're set on changing other areas of shading, 
this won't be too disruptive overall.
I've made a diagram explaining the pipeline here:

and some docs here:

												Color Management, Stage 2: Switch color pipeline to use OpenColorIO
Replace old color pipeline which was supporting linear/sRGB color spaces
only with OpenColorIO-based pipeline.
This introduces two configurable color spaces:
- Input color space for images and movie clips. This space is used to convert
  images/movies from color space in which file is saved to Blender's linear
  space (for float images, byte images are not internally converted, only input
  space is stored for such images and used later).
  This setting could be found in image/clip data block settings.
- Display color space which defines space in which particular display is working.
  This settings could be found in scene's Color Management panel.
When render result is being displayed on the screen, apart from converting image
to display space, some additional conversions could happen.
This conversions are:
- View, which defines tone curve applying before display transformation.
  These are different ways to view the image on the same display device.
  For example it could be used to emulate film view on sRGB display.
- Exposure affects on image exposure before tone map is applied.
- Gamma is post-display gamma correction, could be used to match particular
  display gamma.
- RGB curves are user-defined curves which are applying before display
  transformation, could be used for different purposes.
All this settings by default are only applying on render result and does not
affect on other images. If some particular image needs to be affected by this
transformation, "View as Render" setting of image data block should be set to
truth. Movie clips are always affected by all display transformations.
This commit also introduces configurable color space in which sequencer is
working. This setting could be found in scene's Color Management panel and
it should be used if such stuff as grading needs to be done in color space
different from sRGB (i.e. when Film view on sRGB display is use, using VD16
space as sequencer's internal space would make grading working in space
which is close to the space using for display).
Some technical notes:
- Image buffer's float buffer is now always in linear space, even if it was
  created from 16bit byte images.
- Space of byte buffer is stored in image buffer's rect_colorspace property.
- Profile of image buffer was removed since it's not longer meaningful.
- OpenGL and GLSL is supposed to always work in sRGB space. It is possible
  to support other spaces, but it's quite large project which isn't so
  much important.
- Legacy Color Management option disabled is emulated by using None display.
  It could have some regressions, but there's no clear way to avoid them.
- If OpenColorIO is disabled on build time, it should make blender behaving
  in the same way as previous release with color management enabled.
More details could be found at this page (more details would be added soon):

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

												Changes to Color Management
After testing and feedback, I've decided to slightly modify the way color 
management works internally. While the previous method worked well for 
rendering, was a smaller transition and had some advantages over this
new method, it was a bit more ambiguous, and was making things difficult 
for other areas such as compositing.
This implementation now considers all color data (with only a couple of 
exceptions such as brush colors) to be stored in linear RGB color space, 
rather than sRGB as previously. This brings it in line with Nuke, which also 
operates this way, quite successfully. Color swatches, pickers, color ramp 
display are now gamma corrected to display gamma so you can see what 
you're doing, but the numbers themselves are considered linear. This 
makes understanding blending modes more clear (a 0.5 value on overlay 
will not change the result now) as well as making color swatches act more 
predictably in the compositor, however bringing over color values from 
applications like photoshop or gimp, that operate in a gamma space, 
will give identical results.
This commit will convert over existing files saved by earlier 2.5 versions to 
work generally the same, though there may be some slight differences with 
things like textures. Now that we're set on changing other areas of shading, 
this won't be too disruptive overall.
I've made a diagram explaining the pipeline here:
http://mke3.net/blender/devel/2.5/25_linear_workflow_pipeline.png
and some docs here:

												Color Management, Stage 2: Switch color pipeline to use OpenColorIO
Replace old color pipeline which was supporting linear/sRGB color spaces
only with OpenColorIO-based pipeline.
This introduces two configurable color spaces:
- Input color space for images and movie clips. This space is used to convert
  images/movies from color space in which file is saved to Blender's linear
  space (for float images, byte images are not internally converted, only input
  space is stored for such images and used later).
  This setting could be found in image/clip data block settings.
- Display color space which defines space in which particular display is working.
  This settings could be found in scene's Color Management panel.
When render result is being displayed on the screen, apart from converting image
to display space, some additional conversions could happen.
This conversions are:
- View, which defines tone curve applying before display transformation.
  These are different ways to view the image on the same display device.
  For example it could be used to emulate film view on sRGB display.
- Exposure affects on image exposure before tone map is applied.
- Gamma is post-display gamma correction, could be used to match particular
  display gamma.
- RGB curves are user-defined curves which are applying before display
  transformation, could be used for different purposes.
All this settings by default are only applying on render result and does not
affect on other images. If some particular image needs to be affected by this
transformation, "View as Render" setting of image data block should be set to
truth. Movie clips are always affected by all display transformations.
This commit also introduces configurable color space in which sequencer is
working. This setting could be found in scene's Color Management panel and
it should be used if such stuff as grading needs to be done in color space
different from sRGB (i.e. when Film view on sRGB display is use, using VD16
space as sequencer's internal space would make grading working in space
which is close to the space using for display).
Some technical notes:
- Image buffer's float buffer is now always in linear space, even if it was
  created from 16bit byte images.
- Space of byte buffer is stored in image buffer's rect_colorspace property.
- Profile of image buffer was removed since it's not longer meaningful.
- OpenGL and GLSL is supposed to always work in sRGB space. It is possible
  to support other spaces, but it's quite large project which isn't so
  much important.
- Legacy Color Management option disabled is emulated by using None display.
  It could have some regressions, but there's no clear way to avoid them.
- If OpenColorIO is disabled on build time, it should make blender behaving
  in the same way as previous release with color management enabled.

* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need

												Color Management, Stage 2: Switch color pipeline to use OpenColorIO
Replace old color pipeline which was supporting linear/sRGB color spaces
only with OpenColorIO-based pipeline.
This introduces two configurable color spaces:
- Input color space for images and movie clips. This space is used to convert
  images/movies from color space in which file is saved to Blender's linear
  space (for float images, byte images are not internally converted, only input
  space is stored for such images and used later).
  This setting could be found in image/clip data block settings.
- Display color space which defines space in which particular display is working.
  This settings could be found in scene's Color Management panel.
When render result is being displayed on the screen, apart from converting image
to display space, some additional conversions could happen.
This conversions are:
- View, which defines tone curve applying before display transformation.
  These are different ways to view the image on the same display device.
  For example it could be used to emulate film view on sRGB display.
- Exposure affects on image exposure before tone map is applied.
- Gamma is post-display gamma correction, could be used to match particular
  display gamma.
- RGB curves are user-defined curves which are applying before display
  transformation, could be used for different purposes.
All this settings by default are only applying on render result and does not
affect on other images. If some particular image needs to be affected by this
transformation, "View as Render" setting of image data block should be set to
truth. Movie clips are always affected by all display transformations.
This commit also introduces configurable color space in which sequencer is
working. This setting could be found in scene's Color Management panel and
it should be used if such stuff as grading needs to be done in color space
different from sRGB (i.e. when Film view on sRGB display is use, using VD16
space as sequencer's internal space would make grading working in space
which is close to the space using for display).
Some technical notes:
- Image buffer's float buffer is now always in linear space, even if it was
  created from 16bit byte images.
- Space of byte buffer is stored in image buffer's rect_colorspace property.
- Profile of image buffer was removed since it's not longer meaningful.
- OpenGL and GLSL is supposed to always work in sRGB space. It is possible
  to support other spaces, but it's quite large project which isn't so
  much important.
- Legacy Color Management option disabled is emulated by using None display.
  It could have some regressions, but there's no clear way to avoid them.
- If OpenColorIO is disabled on build time, it should make blender behaving
  in the same way as previous release with color management enabled.

												Color Management, Stage 2: Switch color pipeline to use OpenColorIO
Replace old color pipeline which was supporting linear/sRGB color spaces
only with OpenColorIO-based pipeline.
This introduces two configurable color spaces:
- Input color space for images and movie clips. This space is used to convert
  images/movies from color space in which file is saved to Blender's linear
  space (for float images, byte images are not internally converted, only input
  space is stored for such images and used later).
  This setting could be found in image/clip data block settings.
- Display color space which defines space in which particular display is working.
  This settings could be found in scene's Color Management panel.
When render result is being displayed on the screen, apart from converting image
to display space, some additional conversions could happen.
This conversions are:
- View, which defines tone curve applying before display transformation.
  These are different ways to view the image on the same display device.
  For example it could be used to emulate film view on sRGB display.
- Exposure affects on image exposure before tone map is applied.
- Gamma is post-display gamma correction, could be used to match particular
  display gamma.
- RGB curves are user-defined curves which are applying before display
  transformation, could be used for different purposes.
All this settings by default are only applying on render result and does not
affect on other images. If some particular image needs to be affected by this
transformation, "View as Render" setting of image data block should be set to
truth. Movie clips are always affected by all display transformations.
This commit also introduces configurable color space in which sequencer is
working. This setting could be found in scene's Color Management panel and
it should be used if such stuff as grading needs to be done in color space
different from sRGB (i.e. when Film view on sRGB display is use, using VD16
space as sequencer's internal space would make grading working in space
which is close to the space using for display).
Some technical notes:
- Image buffer's float buffer is now always in linear space, even if it was
  created from 16bit byte images.
- Space of byte buffer is stored in image buffer's rect_colorspace property.
- Profile of image buffer was removed since it's not longer meaningful.
- OpenGL and GLSL is supposed to always work in sRGB space. It is possible
  to support other spaces, but it's quite large project which isn't so
  much important.
- Legacy Color Management option disabled is emulated by using None display.
  It could have some regressions, but there's no clear way to avoid them.
- If OpenColorIO is disabled on build time, it should make blender behaving
  in the same way as previous release with color management enabled.

UI: don't use operators anymore for handling user interface events, but rather
a special UI handler which makes the code clearer. This UI handler is attached
to the region along with other handlers, and also gets a callback when all
handlers for the region are removed to ensure things are properly cleaned up.
This should fix XXX's in the UI code related to events and context switching.
Most of the changes are in interface_handlers.c, which was renamed from
interface_ops.c, to convert operators to the UI handler. UI code notes:
* uiBeginBlock/uiEndBlock/uiFreeBlocks now takes a context argument, this is
  required to properly cancel things like timers or tooltips when the region
  gets removed.
* UI_add_region_handlers will add the region level UI handlers, to be used
  when adding keymap handlers etc. This replaces the UI keymap.
* When the UI code starts a modal interaction (number sliding, text editing,
  opening a menu, ..), it will add an UI handler at the window level which
  will block events.
Windowmanager changes:
* Added an UI handler next to the existing keymap and operator modal handlers.
  It has an event handling and remove callback, and like operator modal handlers
  will remember the area and region if it is registered at the window level.
* Removed the MESSAGE event.
* Operator cancel and UI handler remove callbacks now get the
  window/area/region restored in the context, like the operator modal and UI
  handler event callbacks.
* Regions now receive MOUSEMOVE events for the mouse going outside of the
  region. This was already happening for areas, but UI buttons are at the region
  level so we need it there.
Issues:
* Tooltips and menus stay open when switching to another window, and button
  highlight doesn't work without moving the mouse first when Blender starts up.
  I tried using some events like Q_FIRSTTIME, WINTHAW, but those don't seem to
  arrive..
* Timeline header buttons seem to be moving one pixel or so sometimes when
  interacting with them.
* Seems not due to this commit, but UI and keymap handlers are leaking. It
  seems that handlers are being added to regions in all screens, also in regions
  of areas that are not visible, but these handlers are not removed. Probably
  there should only be handlers in visible regions?

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

Port of part of the Interface code to 2.50.

UI: don't use operators anymore for handling user interface events, but rather
a special UI handler which makes the code clearer. This UI handler is attached
to the region along with other handlers, and also gets a callback when all
handlers for the region are removed to ensure things are properly cleaned up.
This should fix XXX's in the UI code related to events and context switching.
Most of the changes are in interface_handlers.c, which was renamed from
interface_ops.c, to convert operators to the UI handler. UI code notes:
* uiBeginBlock/uiEndBlock/uiFreeBlocks now takes a context argument, this is
  required to properly cancel things like timers or tooltips when the region
  gets removed.
* UI_add_region_handlers will add the region level UI handlers, to be used
  when adding keymap handlers etc. This replaces the UI keymap.
* When the UI code starts a modal interaction (number sliding, text editing,
  opening a menu, ..), it will add an UI handler at the window level which
  will block events.
Windowmanager changes:
* Added an UI handler next to the existing keymap and operator modal handlers.
  It has an event handling and remove callback, and like operator modal handlers
  will remember the area and region if it is registered at the window level.
* Removed the MESSAGE event.
* Operator cancel and UI handler remove callbacks now get the
  window/area/region restored in the context, like the operator modal and UI
  handler event callbacks.
* Regions now receive MOUSEMOVE events for the mouse going outside of the
  region. This was already happening for areas, but UI buttons are at the region
  level so we need it there.
Issues:
* Tooltips and menus stay open when switching to another window, and button
  highlight doesn't work without moving the mouse first when Blender starts up.
  I tried using some events like Q_FIRSTTIME, WINTHAW, but those don't seem to
  arrive..
* Timeline header buttons seem to be moving one pixel or so sometimes when
  interacting with them.
* Seems not due to this commit, but UI and keymap handlers are leaking. It
  seems that handlers are being added to regions in all screens, also in regions
  of areas that are not visible, but these handlers are not removed. Probably
  there should only be handlers in visible regions?

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.

* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.

UI: don't use operators anymore for handling user interface events, but rather
a special UI handler which makes the code clearer. This UI handler is attached
to the region along with other handlers, and also gets a callback when all
handlers for the region are removed to ensure things are properly cleaned up.
This should fix XXX's in the UI code related to events and context switching.
Most of the changes are in interface_handlers.c, which was renamed from
interface_ops.c, to convert operators to the UI handler. UI code notes:
* uiBeginBlock/uiEndBlock/uiFreeBlocks now takes a context argument, this is
  required to properly cancel things like timers or tooltips when the region
  gets removed.
* UI_add_region_handlers will add the region level UI handlers, to be used
  when adding keymap handlers etc. This replaces the UI keymap.
* When the UI code starts a modal interaction (number sliding, text editing,
  opening a menu, ..), it will add an UI handler at the window level which
  will block events.
Windowmanager changes:
* Added an UI handler next to the existing keymap and operator modal handlers.
  It has an event handling and remove callback, and like operator modal handlers
  will remember the area and region if it is registered at the window level.
* Removed the MESSAGE event.
* Operator cancel and UI handler remove callbacks now get the
  window/area/region restored in the context, like the operator modal and UI
  handler event callbacks.
* Regions now receive MOUSEMOVE events for the mouse going outside of the
  region. This was already happening for areas, but UI buttons are at the region
  level so we need it there.
Issues:
* Tooltips and menus stay open when switching to another window, and button
  highlight doesn't work without moving the mouse first when Blender starts up.
  I tried using some events like Q_FIRSTTIME, WINTHAW, but those don't seem to
  arrive..
* Timeline header buttons seem to be moving one pixel or so sometimes when
  interacting with them.
* Seems not due to this commit, but UI and keymap handlers are leaking. It
  seems that handlers are being added to regions in all screens, also in regions
  of areas that are not visible, but these handlers are not removed. Probably
  there should only be handlers in visible regions?

  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

UI: don't use operators anymore for handling user interface events, but rather
a special UI handler which makes the code clearer. This UI handler is attached
to the region along with other handlers, and also gets a callback when all
handlers for the region are removed to ensure things are properly cleaned up.
This should fix XXX's in the UI code related to events and context switching.
Most of the changes are in interface_handlers.c, which was renamed from
interface_ops.c, to convert operators to the UI handler. UI code notes:
* uiBeginBlock/uiEndBlock/uiFreeBlocks now takes a context argument, this is
  required to properly cancel things like timers or tooltips when the region
  gets removed.
* UI_add_region_handlers will add the region level UI handlers, to be used
  when adding keymap handlers etc. This replaces the UI keymap.
* When the UI code starts a modal interaction (number sliding, text editing,
  opening a menu, ..), it will add an UI handler at the window level which
  will block events.
Windowmanager changes:
* Added an UI handler next to the existing keymap and operator modal handlers.
  It has an event handling and remove callback, and like operator modal handlers
  will remember the area and region if it is registered at the window level.
* Removed the MESSAGE event.
* Operator cancel and UI handler remove callbacks now get the
  window/area/region restored in the context, like the operator modal and UI
  handler event callbacks.
* Regions now receive MOUSEMOVE events for the mouse going outside of the
  region. This was already happening for areas, but UI buttons are at the region
  level so we need it there.
Issues:
* Tooltips and menus stay open when switching to another window, and button
  highlight doesn't work without moving the mouse first when Blender starts up.
  I tried using some events like Q_FIRSTTIME, WINTHAW, but those don't seem to
  arrive..
* Timeline header buttons seem to be moving one pixel or so sometimes when
  interacting with them.
* Seems not due to this commit, but UI and keymap handlers are leaking. It
  seems that handlers are being added to regions in all screens, also in regions
  of areas that are not visible, but these handlers are not removed. Probably
  there should only be handlers in visible regions?

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

UI: don't use operators anymore for handling user interface events, but rather
a special UI handler which makes the code clearer. This UI handler is attached
to the region along with other handlers, and also gets a callback when all
handlers for the region are removed to ensure things are properly cleaned up.
This should fix XXX's in the UI code related to events and context switching.
Most of the changes are in interface_handlers.c, which was renamed from
interface_ops.c, to convert operators to the UI handler. UI code notes:
* uiBeginBlock/uiEndBlock/uiFreeBlocks now takes a context argument, this is
  required to properly cancel things like timers or tooltips when the region
  gets removed.
* UI_add_region_handlers will add the region level UI handlers, to be used
  when adding keymap handlers etc. This replaces the UI keymap.
* When the UI code starts a modal interaction (number sliding, text editing,
  opening a menu, ..), it will add an UI handler at the window level which
  will block events.
Windowmanager changes:
* Added an UI handler next to the existing keymap and operator modal handlers.
  It has an event handling and remove callback, and like operator modal handlers
  will remember the area and region if it is registered at the window level.
* Removed the MESSAGE event.
* Operator cancel and UI handler remove callbacks now get the
  window/area/region restored in the context, like the operator modal and UI
  handler event callbacks.
* Regions now receive MOUSEMOVE events for the mouse going outside of the
  region. This was already happening for areas, but UI buttons are at the region
  level so we need it there.
Issues:
* Tooltips and menus stay open when switching to another window, and button
  highlight doesn't work without moving the mouse first when Blender starts up.
  I tried using some events like Q_FIRSTTIME, WINTHAW, but those don't seem to
  arrive..
* Timeline header buttons seem to be moving one pixel or so sometimes when
  interacting with them.
* Seems not due to this commit, but UI and keymap handlers are leaking. It
  seems that handlers are being added to regions in all screens, also in regions
  of areas that are not visible, but these handlers are not removed. Probably
  there should only be handlers in visible regions?

  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu

  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out

UI: don't use operators anymore for handling user interface events, but rather
a special UI handler which makes the code clearer. This UI handler is attached
to the region along with other handlers, and also gets a callback when all
handlers for the region are removed to ensure things are properly cleaned up.
This should fix XXX's in the UI code related to events and context switching.
Most of the changes are in interface_handlers.c, which was renamed from
interface_ops.c, to convert operators to the UI handler. UI code notes:
* uiBeginBlock/uiEndBlock/uiFreeBlocks now takes a context argument, this is
  required to properly cancel things like timers or tooltips when the region
  gets removed.
* UI_add_region_handlers will add the region level UI handlers, to be used
  when adding keymap handlers etc. This replaces the UI keymap.
* When the UI code starts a modal interaction (number sliding, text editing,
  opening a menu, ..), it will add an UI handler at the window level which
  will block events.
Windowmanager changes:
* Added an UI handler next to the existing keymap and operator modal handlers.
  It has an event handling and remove callback, and like operator modal handlers
  will remember the area and region if it is registered at the window level.
* Removed the MESSAGE event.
* Operator cancel and UI handler remove callbacks now get the
  window/area/region restored in the context, like the operator modal and UI
  handler event callbacks.
* Regions now receive MOUSEMOVE events for the mouse going outside of the
  region. This was already happening for areas, but UI buttons are at the region
  level so we need it there.
Issues:
* Tooltips and menus stay open when switching to another window, and button
  highlight doesn't work without moving the mouse first when Blender starts up.
  I tried using some events like Q_FIRSTTIME, WINTHAW, but those don't seem to
  arrive..
* Timeline header buttons seem to be moving one pixel or so sometimes when
  interacting with them.
* Seems not due to this commit, but UI and keymap handlers are leaking. It
  seems that handlers are being added to regions in all screens, also in regions
  of areas that are not visible, but these handlers are not removed. Probably
  there should only be handlers in visible regions?

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

UI: don't use operators anymore for handling user interface events, but rather
a special UI handler which makes the code clearer. This UI handler is attached
to the region along with other handlers, and also gets a callback when all
handlers for the region are removed to ensure things are properly cleaned up.
This should fix XXX's in the UI code related to events and context switching.
Most of the changes are in interface_handlers.c, which was renamed from
interface_ops.c, to convert operators to the UI handler. UI code notes:
* uiBeginBlock/uiEndBlock/uiFreeBlocks now takes a context argument, this is
  required to properly cancel things like timers or tooltips when the region
  gets removed.
* UI_add_region_handlers will add the region level UI handlers, to be used
  when adding keymap handlers etc. This replaces the UI keymap.
* When the UI code starts a modal interaction (number sliding, text editing,
  opening a menu, ..), it will add an UI handler at the window level which
  will block events.
Windowmanager changes:
* Added an UI handler next to the existing keymap and operator modal handlers.
  It has an event handling and remove callback, and like operator modal handlers
  will remember the area and region if it is registered at the window level.
* Removed the MESSAGE event.
* Operator cancel and UI handler remove callbacks now get the
  window/area/region restored in the context, like the operator modal and UI
  handler event callbacks.
* Regions now receive MOUSEMOVE events for the mouse going outside of the
  region. This was already happening for areas, but UI buttons are at the region
  level so we need it there.
Issues:
* Tooltips and menus stay open when switching to another window, and button
  highlight doesn't work without moving the mouse first when Blender starts up.
  I tried using some events like Q_FIRSTTIME, WINTHAW, but those don't seem to
  arrive..
* Timeline header buttons seem to be moving one pixel or so sometimes when
  interacting with them.
* Seems not due to this commit, but UI and keymap handlers are leaking. It
  seems that handlers are being added to regions in all screens, also in regions
  of areas that are not visible, but these handlers are not removed. Probably
  there should only be handlers in visible regions?

This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

UI: don't use operators anymore for handling user interface events, but rather
a special UI handler which makes the code clearer. This UI handler is attached
to the region along with other handlers, and also gets a callback when all
handlers for the region are removed to ensure things are properly cleaned up.
This should fix XXX's in the UI code related to events and context switching.
Most of the changes are in interface_handlers.c, which was renamed from
interface_ops.c, to convert operators to the UI handler. UI code notes:
* uiBeginBlock/uiEndBlock/uiFreeBlocks now takes a context argument, this is
  required to properly cancel things like timers or tooltips when the region
  gets removed.
* UI_add_region_handlers will add the region level UI handlers, to be used
  when adding keymap handlers etc. This replaces the UI keymap.
* When the UI code starts a modal interaction (number sliding, text editing,
  opening a menu, ..), it will add an UI handler at the window level which
  will block events.
Windowmanager changes:
* Added an UI handler next to the existing keymap and operator modal handlers.
  It has an event handling and remove callback, and like operator modal handlers
  will remember the area and region if it is registered at the window level.
* Removed the MESSAGE event.
* Operator cancel and UI handler remove callbacks now get the
  window/area/region restored in the context, like the operator modal and UI
  handler event callbacks.
* Regions now receive MOUSEMOVE events for the mouse going outside of the
  region. This was already happening for areas, but UI buttons are at the region
  level so we need it there.
Issues:
* Tooltips and menus stay open when switching to another window, and button
  highlight doesn't work without moving the mouse first when Blender starts up.
  I tried using some events like Q_FIRSTTIME, WINTHAW, but those don't seem to
  arrive..
* Timeline header buttons seem to be moving one pixel or so sometimes when
  interacting with them.
* Seems not due to this commit, but UI and keymap handlers are leaking. It
  seems that handlers are being added to regions in all screens, also in regions
  of areas that are not visible, but these handlers are not removed. Probably
  there should only be handlers in visible regions?

  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.

  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it

UI: don't use operators anymore for handling user interface events, but rather
a special UI handler which makes the code clearer. This UI handler is attached
to the region along with other handlers, and also gets a callback when all
handlers for the region are removed to ensure things are properly cleaned up.
This should fix XXX's in the UI code related to events and context switching.
Most of the changes are in interface_handlers.c, which was renamed from
interface_ops.c, to convert operators to the UI handler. UI code notes:
* uiBeginBlock/uiEndBlock/uiFreeBlocks now takes a context argument, this is
  required to properly cancel things like timers or tooltips when the region
  gets removed.
* UI_add_region_handlers will add the region level UI handlers, to be used
  when adding keymap handlers etc. This replaces the UI keymap.
* When the UI code starts a modal interaction (number sliding, text editing,
  opening a menu, ..), it will add an UI handler at the window level which
  will block events.
Windowmanager changes:
* Added an UI handler next to the existing keymap and operator modal handlers.
  It has an event handling and remove callback, and like operator modal handlers
  will remember the area and region if it is registered at the window level.
* Removed the MESSAGE event.
* Operator cancel and UI handler remove callbacks now get the
  window/area/region restored in the context, like the operator modal and UI
  handler event callbacks.
* Regions now receive MOUSEMOVE events for the mouse going outside of the
  region. This was already happening for areas, but UI buttons are at the region
  level so we need it there.
Issues:
* Tooltips and menus stay open when switching to another window, and button
  highlight doesn't work without moving the mouse first when Blender starts up.
  I tried using some events like Q_FIRSTTIME, WINTHAW, but those don't seem to
  arrive..
* Timeline header buttons seem to be moving one pixel or so sometimes when
  interacting with them.
* Seems not due to this commit, but UI and keymap handlers are leaking. It
  seems that handlers are being added to regions in all screens, also in regions
  of areas that are not visible, but these handlers are not removed. Probably
  there should only be handlers in visible regions?

  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.

  are still created that way and ui_positionblock still works with window

UI: don't use operators anymore for handling user interface events, but rather
a special UI handler which makes the code clearer. This UI handler is attached
to the region along with other handlers, and also gets a callback when all
handlers for the region are removed to ensure things are properly cleaned up.
This should fix XXX's in the UI code related to events and context switching.
Most of the changes are in interface_handlers.c, which was renamed from
interface_ops.c, to convert operators to the UI handler. UI code notes:
* uiBeginBlock/uiEndBlock/uiFreeBlocks now takes a context argument, this is
  required to properly cancel things like timers or tooltips when the region
  gets removed.
* UI_add_region_handlers will add the region level UI handlers, to be used
  when adding keymap handlers etc. This replaces the UI keymap.
* When the UI code starts a modal interaction (number sliding, text editing,
  opening a menu, ..), it will add an UI handler at the window level which
  will block events.
Windowmanager changes:
* Added an UI handler next to the existing keymap and operator modal handlers.
  It has an event handling and remove callback, and like operator modal handlers
  will remember the area and region if it is registered at the window level.
* Removed the MESSAGE event.
* Operator cancel and UI handler remove callbacks now get the
  window/area/region restored in the context, like the operator modal and UI
  handler event callbacks.
* Regions now receive MOUSEMOVE events for the mouse going outside of the
  region. This was already happening for areas, but UI buttons are at the region
  level so we need it there.
Issues:
* Tooltips and menus stay open when switching to another window, and button
  highlight doesn't work without moving the mouse first when Blender starts up.
  I tried using some events like Q_FIRSTTIME, WINTHAW, but those don't seem to
  arrive..
* Timeline header buttons seem to be moving one pixel or so sometimes when
  interacting with them.
* Seems not due to this commit, but UI and keymap handlers are leaking. It
  seems that handlers are being added to regions in all screens, also in regions
  of areas that are not visible, but these handlers are not removed. Probably
  there should only be handlers in visible regions?

UI: don't use operators anymore for handling user interface events, but rather
a special UI handler which makes the code clearer. This UI handler is attached
to the region along with other handlers, and also gets a callback when all
handlers for the region are removed to ensure things are properly cleaned up.
This should fix XXX's in the UI code related to events and context switching.
Most of the changes are in interface_handlers.c, which was renamed from
interface_ops.c, to convert operators to the UI handler. UI code notes:
* uiBeginBlock/uiEndBlock/uiFreeBlocks now takes a context argument, this is
  required to properly cancel things like timers or tooltips when the region
  gets removed.
* UI_add_region_handlers will add the region level UI handlers, to be used
  when adding keymap handlers etc. This replaces the UI keymap.
* When the UI code starts a modal interaction (number sliding, text editing,
  opening a menu, ..), it will add an UI handler at the window level which
  will block events.
Windowmanager changes:
* Added an UI handler next to the existing keymap and operator modal handlers.
  It has an event handling and remove callback, and like operator modal handlers
  will remember the area and region if it is registered at the window level.
* Removed the MESSAGE event.
* Operator cancel and UI handler remove callbacks now get the
  window/area/region restored in the context, like the operator modal and UI
  handler event callbacks.
* Regions now receive MOUSEMOVE events for the mouse going outside of the
  region. This was already happening for areas, but UI buttons are at the region
  level so we need it there.
Issues:
* Tooltips and menus stay open when switching to another window, and button
  highlight doesn't work without moving the mouse first when Blender starts up.
  I tried using some events like Q_FIRSTTIME, WINTHAW, but those don't seem to
  arrive..
* Timeline header buttons seem to be moving one pixel or so sometimes when
  interacting with them.
* Seems not due to this commit, but UI and keymap handlers are leaking. It
  seems that handlers are being added to regions in all screens, also in regions
  of areas that are not visible, but these handlers are not removed. Probably
  there should only be handlers in visible regions?

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.

  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

UI: don't use operators anymore for handling user interface events, but rather
a special UI handler which makes the code clearer. This UI handler is attached
to the region along with other handlers, and also gets a callback when all
handlers for the region are removed to ensure things are properly cleaned up.
This should fix XXX's in the UI code related to events and context switching.
Most of the changes are in interface_handlers.c, which was renamed from
interface_ops.c, to convert operators to the UI handler. UI code notes:
* uiBeginBlock/uiEndBlock/uiFreeBlocks now takes a context argument, this is
  required to properly cancel things like timers or tooltips when the region
  gets removed.
* UI_add_region_handlers will add the region level UI handlers, to be used
  when adding keymap handlers etc. This replaces the UI keymap.
* When the UI code starts a modal interaction (number sliding, text editing,
  opening a menu, ..), it will add an UI handler at the window level which
  will block events.
Windowmanager changes:
* Added an UI handler next to the existing keymap and operator modal handlers.
  It has an event handling and remove callback, and like operator modal handlers
  will remember the area and region if it is registered at the window level.
* Removed the MESSAGE event.
* Operator cancel and UI handler remove callbacks now get the
  window/area/region restored in the context, like the operator modal and UI
  handler event callbacks.
* Regions now receive MOUSEMOVE events for the mouse going outside of the
  region. This was already happening for areas, but UI buttons are at the region
  level so we need it there.
Issues:
* Tooltips and menus stay open when switching to another window, and button
  highlight doesn't work without moving the mouse first when Blender starts up.
  I tried using some events like Q_FIRSTTIME, WINTHAW, but those don't seem to
  arrive..
* Timeline header buttons seem to be moving one pixel or so sometimes when
  interacting with them.
* Seems not due to this commit, but UI and keymap handlers are leaking. It
  seems that handlers are being added to regions in all screens, also in regions
  of areas that are not visible, but these handlers are not removed. Probably
  there should only be handlers in visible regions?

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need

  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a

UI: don't use operators anymore for handling user interface events, but rather
a special UI handler which makes the code clearer. This UI handler is attached
to the region along with other handlers, and also gets a callback when all
handlers for the region are removed to ensure things are properly cleaned up.
This should fix XXX's in the UI code related to events and context switching.
Most of the changes are in interface_handlers.c, which was renamed from
interface_ops.c, to convert operators to the UI handler. UI code notes:
* uiBeginBlock/uiEndBlock/uiFreeBlocks now takes a context argument, this is
  required to properly cancel things like timers or tooltips when the region
  gets removed.
* UI_add_region_handlers will add the region level UI handlers, to be used
  when adding keymap handlers etc. This replaces the UI keymap.
* When the UI code starts a modal interaction (number sliding, text editing,
  opening a menu, ..), it will add an UI handler at the window level which
  will block events.
Windowmanager changes:
* Added an UI handler next to the existing keymap and operator modal handlers.
  It has an event handling and remove callback, and like operator modal handlers
  will remember the area and region if it is registered at the window level.
* Removed the MESSAGE event.
* Operator cancel and UI handler remove callbacks now get the
  window/area/region restored in the context, like the operator modal and UI
  handler event callbacks.
* Regions now receive MOUSEMOVE events for the mouse going outside of the
  region. This was already happening for areas, but UI buttons are at the region
  level so we need it there.
Issues:
* Tooltips and menus stay open when switching to another window, and button
  highlight doesn't work without moving the mouse first when Blender starts up.
  I tried using some events like Q_FIRSTTIME, WINTHAW, but those don't seem to
  arrive..
* Timeline header buttons seem to be moving one pixel or so sometimes when
  interacting with them.
* Seems not due to this commit, but UI and keymap handlers are leaking. It
  seems that handlers are being added to regions in all screens, also in regions
  of areas that are not visible, but these handlers are not removed. Probably
  there should only be handlers in visible regions?

  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

Port of part of the Interface code to 2.50.

UI: don't use operators anymore for handling user interface events, but rather
a special UI handler which makes the code clearer. This UI handler is attached
to the region along with other handlers, and also gets a callback when all
handlers for the region are removed to ensure things are properly cleaned up.
This should fix XXX's in the UI code related to events and context switching.
Most of the changes are in interface_handlers.c, which was renamed from
interface_ops.c, to convert operators to the UI handler. UI code notes:
* uiBeginBlock/uiEndBlock/uiFreeBlocks now takes a context argument, this is
  required to properly cancel things like timers or tooltips when the region
  gets removed.
* UI_add_region_handlers will add the region level UI handlers, to be used
  when adding keymap handlers etc. This replaces the UI keymap.
* When the UI code starts a modal interaction (number sliding, text editing,
  opening a menu, ..), it will add an UI handler at the window level which
  will block events.
Windowmanager changes:
* Added an UI handler next to the existing keymap and operator modal handlers.
  It has an event handling and remove callback, and like operator modal handlers
  will remember the area and region if it is registered at the window level.
* Removed the MESSAGE event.
* Operator cancel and UI handler remove callbacks now get the
  window/area/region restored in the context, like the operator modal and UI
  handler event callbacks.
* Regions now receive MOUSEMOVE events for the mouse going outside of the
  region. This was already happening for areas, but UI buttons are at the region
  level so we need it there.
Issues:
* Tooltips and menus stay open when switching to another window, and button
  highlight doesn't work without moving the mouse first when Blender starts up.
  I tried using some events like Q_FIRSTTIME, WINTHAW, but those don't seem to
  arrive..
* Timeline header buttons seem to be moving one pixel or so sometimes when
  interacting with them.
* Seems not due to this commit, but UI and keymap handlers are leaking. It
  seems that handlers are being added to regions in all screens, also in regions
  of areas that are not visible, but these handlers are not removed. Probably
  there should only be handlers in visible regions?

* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

												Holiday coding log :)
Nice formatted version (pictures soon):
http://wiki.blender.org/index.php/Dev:Ref/Release_Notes/2.66/Usability
Short list of main changes:
- Transparent region option (over main region), added code to blend in/out such panels.
- Min size window now 640 x 480
- Fixed DPI for ui - lots of cleanup and changes everywhere. Icon image need correct size still, layer-in-use icon needs remake.
- Macbook retina support, use command line --no-native-pixels to disable it
- Timeline Marker label was drawing wrong
- Trackpad and magic mouse: supports zoom (hold ctrl)
- Fix for splash position: removed ghost function and made window size update after creation immediate
- Fast undo buffer save now adds UI as well. Could be checked for regular file save even...
  Quit.blend and temp file saving use this now.
- Dixed filename in window on reading quit.blend or temp saves, and they now add a warning in window title: "(Recovered)"
- New Userpref option "Keep Session" - this always saves quit.blend, and loads on start.
  This allows keeping UI and data without actual saves, until you actually save.
  When you load startup.blend and quit, it recognises the quit.blend as a startup (no file name in header)
- Added 3D view copy/paste buffers (selected objects). Shortcuts ctrl-c, ctrl-v (OSX, cmd-c, cmd-v). 
  Coded partial file saving for it. Could be used for other purposes. Todo: use OS clipboards. 
- User preferences (themes, keymaps, user settings) now can be saved as a separate file.
  Old option is called "Save Startup File" the new one "Save User Settings".
  To visualise this difference, the 'save startup file' button has been removed from user preferences window. That option is available as CTRL+U and in File menu still.
- OSX: fixed bug that stopped giving mouse events outside window.
  This also fixes "Continuous Grab" for OSX. (error since 2009)

												KEYMAP REFACTORING
Diff Keymaps
User edited keymaps now no longer override the builtin keymaps entirely, but
rather save only the difference and reapply those changes. This means they can
stay better in sync when the builtin keymaps change. The diff/patch algorithm
is not perfect, but better for the common case where only a few items are changed
rather than entire keymaps The main weakness is that if a builtin keymap item
changes, user modification of that item may need to be redone in some cases.
Keymap Editor
The most noticeable change here is that there is no longer an "Edit" button for
keymaps, all are editable immediately, but a "Restore" buttons shows for keymaps
and items that have been edited. Shortcuts for addons can also be edited in the
keymap editor. 
Addons
Addons now should only modify the new addon keyconfiguration, the keymap items
there will be added to the builtin ones for handling events, and not get lost
when starting new files. Example code of register/unregister:
km = wm.keyconfigs.addon.keymaps.new("3D View", space_type="VIEW_3D")
km.keymap_items.new('my.operator', 'ESC', 'PRESS')
km = wm.keyconfigs.addon.keymaps["3D View"]
km.keymap_items.remove(km.keymap_items["my.operator"])
Compatibility
The changes made are not forward compatible, i.e. if you save user preferences
with newer versions, older versions will not have key configuration changes that
were made.

Compatibility
The changes made are not forward compatible, i.e. if you save user preferences
with newer versions, older versions will not have key configuration changes that
were made.

												KEYMAP REFACTORING
Diff Keymaps
User edited keymaps now no longer override the builtin keymaps entirely, but
rather save only the difference and reapply those changes. This means they can
stay better in sync when the builtin keymaps change. The diff/patch algorithm
is not perfect, but better for the common case where only a few items are changed
rather than entire keymaps The main weakness is that if a builtin keymap item
changes, user modification of that item may need to be redone in some cases.
Keymap Editor
The most noticeable change here is that there is no longer an "Edit" button for
keymaps, all are editable immediately, but a "Restore" buttons shows for keymaps
and items that have been edited. Shortcuts for addons can also be edited in the
keymap editor. 
Addons
Addons now should only modify the new addon keyconfiguration, the keymap items
there will be added to the builtin ones for handling events, and not get lost

												UI translation from inside Blender UI: first part.
This commit reshapes a bit runtime button info getter, by adding a new uiButGetStrInfo() which accepts a variable number of uiStringInfo parameters, and tries to fill them with the requested strings, for the given button (label, tip, context, RNA identifier, keymap, etc.). Currently used mostly by existing ui_tooltip_create(), and new UI_OT_edittranslation_init operator.
It also adds a few getters (to get RNA i18n context, and current language iso code).
Finally, it adds to C operators needed for the py ui_translation addon:
*UI_OT_edittranslation_init, which gathers requested data and launch the py operator.
*UI_OT_reloadtranslation, which forces a full reload of the whole UI translation (including rechecking the directory containing mo files).
For the first operator to work, it also adds a new user preferences path: i18n_branches_directory, to point to the /branch part of a bf-translation checkout.

												UI translation from inside Blender UI: first part.
This commit reshapes a bit runtime button info getter, by adding a new uiButGetStrInfo() which accepts a variable number of uiStringInfo parameters, and tries to fill them with the requested strings, for the given button (label, tip, context, RNA identifier, keymap, etc.). Currently used mostly by existing ui_tooltip_create(), and new UI_OT_edittranslation_init operator.
It also adds a few getters (to get RNA i18n context, and current language iso code).
Finally, it adds to C operators needed for the py ui_translation addon:
*UI_OT_edittranslation_init, which gathers requested data and launch the py operator.
*UI_OT_reloadtranslation, which forces a full reload of the whole UI translation (including rechecking the directory containing mo files).
For the first operator to work, it also adds a new user preferences path: i18n_branches_directory, to point to the /branch part of a bf-translation checkout.

												UI translation from inside Blender UI: first part.
This commit reshapes a bit runtime button info getter, by adding a new uiButGetStrInfo() which accepts a variable number of uiStringInfo parameters, and tries to fill them with the requested strings, for the given button (label, tip, context, RNA identifier, keymap, etc.). Currently used mostly by existing ui_tooltip_create(), and new UI_OT_edittranslation_init operator.
It also adds a few getters (to get RNA i18n context, and current language iso code).
Finally, it adds to C operators needed for the py ui_translation addon:
*UI_OT_edittranslation_init, which gathers requested data and launch the py operator.
*UI_OT_reloadtranslation, which forces a full reload of the whole UI translation (including rechecking the directory containing mo files).
For the first operator to work, it also adds a new user preferences path: i18n_branches_directory, to point to the /branch part of a bf-translation checkout.

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

UI: don't use operators anymore for handling user interface events, but rather
a special UI handler which makes the code clearer. This UI handler is attached
to the region along with other handlers, and also gets a callback when all
handlers for the region are removed to ensure things are properly cleaned up.
This should fix XXX's in the UI code related to events and context switching.
Most of the changes are in interface_handlers.c, which was renamed from
interface_ops.c, to convert operators to the UI handler. UI code notes:
* uiBeginBlock/uiEndBlock/uiFreeBlocks now takes a context argument, this is
  required to properly cancel things like timers or tooltips when the region
  gets removed.
* UI_add_region_handlers will add the region level UI handlers, to be used
  when adding keymap handlers etc. This replaces the UI keymap.
* When the UI code starts a modal interaction (number sliding, text editing,
  opening a menu, ..), it will add an UI handler at the window level which
  will block events.
Windowmanager changes:
* Added an UI handler next to the existing keymap and operator modal handlers.
  It has an event handling and remove callback, and like operator modal handlers
  will remember the area and region if it is registered at the window level.
* Removed the MESSAGE event.
* Operator cancel and UI handler remove callbacks now get the
  window/area/region restored in the context, like the operator modal and UI
  handler event callbacks.
* Regions now receive MOUSEMOVE events for the mouse going outside of the
  region. This was already happening for areas, but UI buttons are at the region
  level so we need it there.
Issues:
* Tooltips and menus stay open when switching to another window, and button
  highlight doesn't work without moving the mouse first when Blender starts up.
  I tried using some events like Q_FIRSTTIME, WINTHAW, but those don't seem to
  arrive..
* Timeline header buttons seem to be moving one pixel or so sometimes when
  interacting with them.
* Seems not due to this commit, but UI and keymap handlers are leaking. It
  seems that handlers are being added to regions in all screens, also in regions
  of areas that are not visible, but these handlers are not removed. Probably
  there should only be handlers in visible regions?

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

												2.5: ID datablock button back, previously known as std_libbuttons. The
way this worked in 2.4x wasn't really clean, with events going all over
the place and using dubious variables such as G.but->lockpoin or
G.sima->menunr. It works as follows now, for example:
xco= uiDefIDPoinButs(block, CTX_data_main(C), NULL, (ID**)&sima->image, ID_IM, &sima->pin, xco, yco,
	sima_idpoin_handle, UI_ID_BROWSE|UI_ID_RENAME|UI_ID_ADD_NEW|UI_ID_OPEN|UI_ID_DELETE|UI_ID_ALONE|UI_ID_PIN);
The last two parameters are a callback function, and a list of events
or functionalities that are supported. The callback function will then
get the ID pointer + event to handle.

  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need

  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it

* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full

												Drag and drop 2.5 integration! Finally, slashdot regulars can use
Blender too now! :)
** Drag works as follows:
- drag-able items are defined by the standard interface ui toolkit
- each button can get this feature, via uiButSetDragXXX(but, ...).
  There are calls to define drag-able images, ID blocks, RNA paths, 
  file paths, and so on. By default you drag an icon, exceptionally 
  an ImBuf
- Drag items are registered centrally in the WM, it allows more drag 
  items simultaneous too, but not implemented
** Drop works as follows:
- On mouse release, and if drag items exist in the WM, it converts 
  the mouse event to an EVT_DROP type. This event then gets the full 
  drag info as customdata
- drop regions are defined with WM_dropbox_add(), similar to keymaps 
  you can make a "drop map" this way, which become 'drop map handlers' 
  in the queues.
- next to that the UI kit handles some common button types (like 
  accepting ID or names) to be catching a drop event too.
- Every "drop box" has two callbacks:
  - poll() = check if the event drag data is relevant for this box
  - copy() = fill in custom properties in the dropbox to initialize 
    an operator
- The dropbox handler then calls its standard Operator with its 
  dropbox properties.
** Currently implemented
Drag items:
- ID icons in browse buttons
- ID icons in context menu of properties region
- ID icons in outliner and rna viewer
- FileBrowser icons
- FileBrowser preview images
Drag-able icons are subtly visualized by making them brighter a bit 
on mouse-over. In case the icon is a button or UI element too (most 
cases), the drag-able feature will make the item react to 
mouse-release instead of mouse-press. 
Drop options:
- UI buttons: ID and text buttons (paste name)
- View3d: Object ID drop copies object
- View3d: Material ID drop assigns to object under cursor
- View3d: Image ID drop assigns to object UV texture under cursor
- Sequencer: Path drop will add either Image or Movie strip
- Image window: Path drop will open image
** Drag and drop Notes:
- Dropping into another Blender window (from same application) works 
too. I've added code that passes on mousemoves and clicks to other 
windows, without activating them though. This does make using multi-window
Blender a bit friendler.
- Dropping a file path to an image, is not the same as dropping an 
Image ID... keep this in mind. Sequencer for example wants paths to 
be dropped,  textures in 3d window wants an Image ID.
- Although drop boxes could be defined via Python, I suggest they're 
part of the UI and editor design (= how we want an editor to work), and 
not default offered configurable like keymaps. 
- At the moment only one item can be dragged at a time. This is for 
several reasons.... For one, Blender doesn't have a well defined 
uniform way to define "what is selected" (files, outliner items, etc). 
Secondly there's potential conflicts on what todo when you drop mixed 
drag sets on spots. All undefined stuff... nice for later.
- Example to bypass the above: a collection of images that form a strip, 
should be represented in filewindow as a single sequence anyway. 
This then will fit well and gets handled neatly by design.
- Another option to check is to allow multiple options per drop... it 
could show the operator as a sort of menu, allowing arrow or scrollwheel 
to choose. For time being I'd prefer to try to design a singular drop 
though, just offer only one drop action per data type on given spots.
- What does work already, but a tad slow, is to use a function that 
detects an object (type) under cursor, so a drag item's option can be 
further refined (like drop object on object = parent). (disabled)
** More notes
- Added saving for Region layouts (like split points for toolbar)
- Label buttons now handle mouse over
- File list: added full path entry for drop feature.
- Filesel bugfix: wm_operator_exec() got called there and fully handled, 
while WM event code tried same. Added new OPERATOR_HANDLED flag for this. 
Maybe python needs it too?
- Cocoa: added window move event, so multi-win setups work OK (didnt save).
- Interface_handlers.c: removed win->active
- Severe area copy bug: area handlers were not set to NULL

												Drag and drop 2.5 integration! Finally, slashdot regulars can use
Blender too now! :)
** Drag works as follows:
- drag-able items are defined by the standard interface ui toolkit
- each button can get this feature, via uiButSetDragXXX(but, ...).
  There are calls to define drag-able images, ID blocks, RNA paths, 
  file paths, and so on. By default you drag an icon, exceptionally 
  an ImBuf
- Drag items are registered centrally in the WM, it allows more drag 
  items simultaneous too, but not implemented
** Drop works as follows:
- On mouse release, and if drag items exist in the WM, it converts 
  the mouse event to an EVT_DROP type. This event then gets the full 
  drag info as customdata
- drop regions are defined with WM_dropbox_add(), similar to keymaps 
  you can make a "drop map" this way, which become 'drop map handlers' 
  in the queues.
- next to that the UI kit handles some common button types (like 
  accepting ID or names) to be catching a drop event too.
- Every "drop box" has two callbacks:
  - poll() = check if the event drag data is relevant for this box
  - copy() = fill in custom properties in the dropbox to initialize 
    an operator
- The dropbox handler then calls its standard Operator with its 
  dropbox properties.
** Currently implemented
Drag items:
- ID icons in browse buttons
- ID icons in context menu of properties region
- ID icons in outliner and rna viewer
- FileBrowser icons
- FileBrowser preview images
Drag-able icons are subtly visualized by making them brighter a bit 
on mouse-over. In case the icon is a button or UI element too (most 
cases), the drag-able feature will make the item react to 
mouse-release instead of mouse-press. 
Drop options:
- UI buttons: ID and text buttons (paste name)
- View3d: Object ID drop copies object
- View3d: Material ID drop assigns to object under cursor
- View3d: Image ID drop assigns to object UV texture under cursor
- Sequencer: Path drop will add either Image or Movie strip
- Image window: Path drop will open image
** Drag and drop Notes:
- Dropping into another Blender window (from same application) works 
too. I've added code that passes on mousemoves and clicks to other 
windows, without activating them though. This does make using multi-window
Blender a bit friendler.
- Dropping a file path to an image, is not the same as dropping an 
Image ID... keep this in mind. Sequencer for example wants paths to 
be dropped,  textures in 3d window wants an Image ID.
- Although drop boxes could be defined via Python, I suggest they're 
part of the UI and editor design (= how we want an editor to work), and 
not default offered configurable like keymaps. 
- At the moment only one item can be dragged at a time. This is for 
several reasons.... For one, Blender doesn't have a well defined 
uniform way to define "what is selected" (files, outliner items, etc). 
Secondly there's potential conflicts on what todo when you drop mixed 
drag sets on spots. All undefined stuff... nice for later.
- Example to bypass the above: a collection of images that form a strip, 
should be represented in filewindow as a single sequence anyway. 
This then will fit well and gets handled neatly by design.
- Another option to check is to allow multiple options per drop... it 
could show the operator as a sort of menu, allowing arrow or scrollwheel 
to choose. For time being I'd prefer to try to design a singular drop 
though, just offer only one drop action per data type on given spots.
- What does work already, but a tad slow, is to use a function that 
detects an object (type) under cursor, so a drag item's option can be 
further refined (like drop object on object = parent). (disabled)
** More notes
- Added saving for Region layouts (like split points for toolbar)
- Label buttons now handle mouse over
- File list: added full path entry for drop feature.
- Filesel bugfix: wm_operator_exec() got called there and fully handled, 
while WM event code tried same. Added new OPERATOR_HANDLED flag for this. 
Maybe python needs it too?
- Cocoa: added window move event, so multi-win setups work OK (didnt save).
- Interface_handlers.c: removed win->active
- Severe area copy bug: area handlers were not set to NULL
- Filesel bugfix: next/prev folder list was not copied on area copies
** Leftover todos
- Cocoa windows seem to hang on cases still... needs check
- Cocoa 'draw overlap' swap doesn't work
- Cocoa window loses focus permanently on using Spotlight
  (for these reasons, makefile building has Carbon as default atm)
- ListView templates in UI cannot become dragged yet, needs review...

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

UI: don't use operators anymore for handling user interface events, but rather
a special UI handler which makes the code clearer. This UI handler is attached
to the region along with other handlers, and also gets a callback when all
handlers for the region are removed to ensure things are properly cleaned up.
This should fix XXX's in the UI code related to events and context switching.
Most of the changes are in interface_handlers.c, which was renamed from
interface_ops.c, to convert operators to the UI handler. UI code notes:
* uiBeginBlock/uiEndBlock/uiFreeBlocks now takes a context argument, this is
  required to properly cancel things like timers or tooltips when the region
  gets removed.
* UI_add_region_handlers will add the region level UI handlers, to be used
  when adding keymap handlers etc. This replaces the UI keymap.
* When the UI code starts a modal interaction (number sliding, text editing,
  opening a menu, ..), it will add an UI handler at the window level which
  will block events.
Windowmanager changes:
* Added an UI handler next to the existing keymap and operator modal handlers.
  It has an event handling and remove callback, and like operator modal handlers
  will remember the area and region if it is registered at the window level.
* Removed the MESSAGE event.
* Operator cancel and UI handler remove callbacks now get the
  window/area/region restored in the context, like the operator modal and UI
  handler event callbacks.
* Regions now receive MOUSEMOVE events for the mouse going outside of the
  region. This was already happening for areas, but UI buttons are at the region
  level so we need it there.
Issues:
* Tooltips and menus stay open when switching to another window, and button
  highlight doesn't work without moving the mouse first when Blender starts up.
  I tried using some events like Q_FIRSTTIME, WINTHAW, but those don't seem to
  arrive..
* Timeline header buttons seem to be moving one pixel or so sometimes when
  interacting with them.
* Seems not due to this commit, but UI and keymap handlers are leaking. It
  seems that handlers are being added to regions in all screens, also in regions
  of areas that are not visible, but these handlers are not removed. Probably
  there should only be handlers in visible regions?

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

UI: don't use operators anymore for handling user interface events, but rather
a special UI handler which makes the code clearer. This UI handler is attached
to the region along with other handlers, and also gets a callback when all
handlers for the region are removed to ensure things are properly cleaned up.
This should fix XXX's in the UI code related to events and context switching.
Most of the changes are in interface_handlers.c, which was renamed from
interface_ops.c, to convert operators to the UI handler. UI code notes:
* uiBeginBlock/uiEndBlock/uiFreeBlocks now takes a context argument, this is
  required to properly cancel things like timers or tooltips when the region
  gets removed.
* UI_add_region_handlers will add the region level UI handlers, to be used
  when adding keymap handlers etc. This replaces the UI keymap.
* When the UI code starts a modal interaction (number sliding, text editing,
  opening a menu, ..), it will add an UI handler at the window level which
  will block events.
Windowmanager changes:
* Added an UI handler next to the existing keymap and operator modal handlers.
  It has an event handling and remove callback, and like operator modal handlers
  will remember the area and region if it is registered at the window level.
* Removed the MESSAGE event.
* Operator cancel and UI handler remove callbacks now get the
  window/area/region restored in the context, like the operator modal and UI
  handler event callbacks.
* Regions now receive MOUSEMOVE events for the mouse going outside of the
  region. This was already happening for areas, but UI buttons are at the region
  level so we need it there.
Issues:
* Tooltips and menus stay open when switching to another window, and button
  highlight doesn't work without moving the mouse first when Blender starts up.
  I tried using some events like Q_FIRSTTIME, WINTHAW, but those don't seem to
  arrive..
* Timeline header buttons seem to be moving one pixel or so sometimes when
  interacting with them.
* Seems not due to this commit, but UI and keymap handlers are leaking. It
  seems that handlers are being added to regions in all screens, also in regions
  of areas that are not visible, but these handlers are not removed. Probably
  there should only be handlers in visible regions?

This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

UI: don't use operators anymore for handling user interface events, but rather
a special UI handler which makes the code clearer. This UI handler is attached
to the region along with other handlers, and also gets a callback when all
handlers for the region are removed to ensure things are properly cleaned up.
This should fix XXX's in the UI code related to events and context switching.
Most of the changes are in interface_handlers.c, which was renamed from
interface_ops.c, to convert operators to the UI handler. UI code notes:
* uiBeginBlock/uiEndBlock/uiFreeBlocks now takes a context argument, this is
  required to properly cancel things like timers or tooltips when the region
  gets removed.
* UI_add_region_handlers will add the region level UI handlers, to be used
  when adding keymap handlers etc. This replaces the UI keymap.
* When the UI code starts a modal interaction (number sliding, text editing,
  opening a menu, ..), it will add an UI handler at the window level which
  will block events.
Windowmanager changes:
* Added an UI handler next to the existing keymap and operator modal handlers.
  It has an event handling and remove callback, and like operator modal handlers
  will remember the area and region if it is registered at the window level.
* Removed the MESSAGE event.
* Operator cancel and UI handler remove callbacks now get the
  window/area/region restored in the context, like the operator modal and UI
  handler event callbacks.
* Regions now receive MOUSEMOVE events for the mouse going outside of the
  region. This was already happening for areas, but UI buttons are at the region
  level so we need it there.
Issues:
* Tooltips and menus stay open when switching to another window, and button
  highlight doesn't work without moving the mouse first when Blender starts up.
  I tried using some events like Q_FIRSTTIME, WINTHAW, but those don't seem to
  arrive..
* Timeline header buttons seem to be moving one pixel or so sometimes when
  interacting with them.
* Seems not due to this commit, but UI and keymap handlers are leaking. It
  seems that handlers are being added to regions in all screens, also in regions
  of areas that are not visible, but these handlers are not removed. Probably
  there should only be handlers in visible regions?

												Drag and drop 2.5 integration! Finally, slashdot regulars can use
Blender too now! :)
** Drag works as follows:
- drag-able items are defined by the standard interface ui toolkit
- each button can get this feature, via uiButSetDragXXX(but, ...).
  There are calls to define drag-able images, ID blocks, RNA paths, 
  file paths, and so on. By default you drag an icon, exceptionally 
  an ImBuf
- Drag items are registered centrally in the WM, it allows more drag 
  items simultaneous too, but not implemented
** Drop works as follows:
- On mouse release, and if drag items exist in the WM, it converts 
  the mouse event to an EVT_DROP type. This event then gets the full 
  drag info as customdata
- drop regions are defined with WM_dropbox_add(), similar to keymaps 
  you can make a "drop map" this way, which become 'drop map handlers' 
  in the queues.
- next to that the UI kit handles some common button types (like 
  accepting ID or names) to be catching a drop event too.
- Every "drop box" has two callbacks:
  - poll() = check if the event drag data is relevant for this box
  - copy() = fill in custom properties in the dropbox to initialize 
    an operator
- The dropbox handler then calls its standard Operator with its 
  dropbox properties.
** Currently implemented
Drag items:
- ID icons in browse buttons
- ID icons in context menu of properties region
- ID icons in outliner and rna viewer
- FileBrowser icons
- FileBrowser preview images
Drag-able icons are subtly visualized by making them brighter a bit 
on mouse-over. In case the icon is a button or UI element too (most 
cases), the drag-able feature will make the item react to 
mouse-release instead of mouse-press. 
Drop options:
- UI buttons: ID and text buttons (paste name)
- View3d: Object ID drop copies object
- View3d: Material ID drop assigns to object under cursor
- View3d: Image ID drop assigns to object UV texture under cursor
- Sequencer: Path drop will add either Image or Movie strip
- Image window: Path drop will open image
** Drag and drop Notes:
- Dropping into another Blender window (from same application) works 
too. I've added code that passes on mousemoves and clicks to other 
windows, without activating them though. This does make using multi-window
Blender a bit friendler.
- Dropping a file path to an image, is not the same as dropping an 
Image ID... keep this in mind. Sequencer for example wants paths to 
be dropped,  textures in 3d window wants an Image ID.
- Although drop boxes could be defined via Python, I suggest they're 
part of the UI and editor design (= how we want an editor to work), and 
not default offered configurable like keymaps. 
- At the moment only one item can be dragged at a time. This is for 
several reasons.... For one, Blender doesn't have a well defined 
uniform way to define "what is selected" (files, outliner items, etc). 
Secondly there's potential conflicts on what todo when you drop mixed 
drag sets on spots. All undefined stuff... nice for later.
- Example to bypass the above: a collection of images that form a strip, 
should be represented in filewindow as a single sequence anyway. 
This then will fit well and gets handled neatly by design.
- Another option to check is to allow multiple options per drop... it 
could show the operator as a sort of menu, allowing arrow or scrollwheel 
to choose. For time being I'd prefer to try to design a singular drop 
though, just offer only one drop action per data type on given spots.
- What does work already, but a tad slow, is to use a function that 
detects an object (type) under cursor, so a drag item's option can be 
further refined (like drop object on object = parent). (disabled)
** More notes
- Added saving for Region layouts (like split points for toolbar)
- Label buttons now handle mouse over
- File list: added full path entry for drop feature.
- Filesel bugfix: wm_operator_exec() got called there and fully handled, 
while WM event code tried same. Added new OPERATOR_HANDLED flag for this. 
Maybe python needs it too?
- Cocoa: added window move event, so multi-win setups work OK (didnt save).
- Interface_handlers.c: removed win->active
- Severe area copy bug: area handlers were not set to NULL
- Filesel bugfix: next/prev folder list was not copied on area copies
** Leftover todos
- Cocoa windows seem to hang on cases still... needs check
- Cocoa 'draw overlap' swap doesn't work
- Cocoa window loses focus permanently on using Spotlight
  (for these reasons, makefile building has Carbon as default atm)
- ListView templates in UI cannot become dragged yet, needs review... 
it consists of two overlapping UI elements, preventing handling icon clicks.
- There's already Ghost library code to handle dropping from OS 
into Blender window. I've noticed this code is unfinished for Macs, but 
seems to be complete for Windows. Needs test... currently, an external 
drop event will print in console when succesfully delivered to Blender's WM.

												Drag and drop 2.5 integration! Finally, slashdot regulars can use
Blender too now! :)
** Drag works as follows:
- drag-able items are defined by the standard interface ui toolkit
- each button can get this feature, via uiButSetDragXXX(but, ...).
  There are calls to define drag-able images, ID blocks, RNA paths, 
  file paths, and so on. By default you drag an icon, exceptionally 
  an ImBuf
- Drag items are registered centrally in the WM, it allows more drag 
  items simultaneous too, but not implemented
** Drop works as follows:
- On mouse release, and if drag items exist in the WM, it converts 
  the mouse event to an EVT_DROP type. This event then gets the full 
  drag info as customdata
- drop regions are defined with WM_dropbox_add(), similar to keymaps 
  you can make a "drop map" this way, which become 'drop map handlers' 
  in the queues.
- next to that the UI kit handles some common button types (like 
  accepting ID or names) to be catching a drop event too.
- Every "drop box" has two callbacks:
  - poll() = check if the event drag data is relevant for this box
  - copy() = fill in custom properties in the dropbox to initialize 
    an operator
- The dropbox handler then calls its standard Operator with its 
  dropbox properties.
** Currently implemented
Drag items:
- ID icons in browse buttons
- ID icons in context menu of properties region
- ID icons in outliner and rna viewer
- FileBrowser icons
- FileBrowser preview images
Drag-able icons are subtly visualized by making them brighter a bit 
on mouse-over. In case the icon is a button or UI element too (most 
cases), the drag-able feature will make the item react to 
mouse-release instead of mouse-press. 
Drop options:
- UI buttons: ID and text buttons (paste name)
- View3d: Object ID drop copies object
- View3d: Material ID drop assigns to object under cursor
- View3d: Image ID drop assigns to object UV texture under cursor
- Sequencer: Path drop will add either Image or Movie strip
- Image window: Path drop will open image
** Drag and drop Notes:
- Dropping into another Blender window (from same application) works 
too. I've added code that passes on mousemoves and clicks to other 
windows, without activating them though. This does make using multi-window
Blender a bit friendler.
- Dropping a file path to an image, is not the same as dropping an 
Image ID... keep this in mind. Sequencer for example wants paths to 
be dropped,  textures in 3d window wants an Image ID.
- Although drop boxes could be defined via Python, I suggest they're 
part of the UI and editor design (= how we want an editor to work), and 
not default offered configurable like keymaps. 
- At the moment only one item can be dragged at a time. This is for 
several reasons.... For one, Blender doesn't have a well defined 
uniform way to define "what is selected" (files, outliner items, etc). 
Secondly there's potential conflicts on what todo when you drop mixed 
drag sets on spots. All undefined stuff... nice for later.

UI: don't use operators anymore for handling user interface events, but rather
a special UI handler which makes the code clearer. This UI handler is attached
to the region along with other handlers, and also gets a callback when all
handlers for the region are removed to ensure things are properly cleaned up.
This should fix XXX's in the UI code related to events and context switching.
Most of the changes are in interface_handlers.c, which was renamed from
interface_ops.c, to convert operators to the UI handler. UI code notes:
* uiBeginBlock/uiEndBlock/uiFreeBlocks now takes a context argument, this is
  required to properly cancel things like timers or tooltips when the region
  gets removed.
* UI_add_region_handlers will add the region level UI handlers, to be used
  when adding keymap handlers etc. This replaces the UI keymap.
* When the UI code starts a modal interaction (number sliding, text editing,
  opening a menu, ..), it will add an UI handler at the window level which
  will block events.
Windowmanager changes:
* Added an UI handler next to the existing keymap and operator modal handlers.
  It has an event handling and remove callback, and like operator modal handlers
  will remember the area and region if it is registered at the window level.
* Removed the MESSAGE event.
* Operator cancel and UI handler remove callbacks now get the
  window/area/region restored in the context, like the operator modal and UI
  handler event callbacks.
* Regions now receive MOUSEMOVE events for the mouse going outside of the
  region. This was already happening for areas, but UI buttons are at the region
  level so we need it there.
Issues:
* Tooltips and menus stay open when switching to another window, and button
  highlight doesn't work without moving the mouse first when Blender starts up.
  I tried using some events like Q_FIRSTTIME, WINTHAW, but those don't seem to
  arrive..
* Timeline header buttons seem to be moving one pixel or so sometimes when
  interacting with them.
* Seems not due to this commit, but UI and keymap handlers are leaking. It
  seems that handlers are being added to regions in all screens, also in regions
  of areas that are not visible, but these handlers are not removed. Probably
  there should only be handlers in visible regions?

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

UI: don't use operators anymore for handling user interface events, but rather
a special UI handler which makes the code clearer. This UI handler is attached
to the region along with other handlers, and also gets a callback when all
handlers for the region are removed to ensure things are properly cleaned up.
This should fix XXX's in the UI code related to events and context switching.
Most of the changes are in interface_handlers.c, which was renamed from
interface_ops.c, to convert operators to the UI handler. UI code notes:
* uiBeginBlock/uiEndBlock/uiFreeBlocks now takes a context argument, this is
  required to properly cancel things like timers or tooltips when the region
  gets removed.
* UI_add_region_handlers will add the region level UI handlers, to be used
  when adding keymap handlers etc. This replaces the UI keymap.
* When the UI code starts a modal interaction (number sliding, text editing,
  opening a menu, ..), it will add an UI handler at the window level which
  will block events.
Windowmanager changes:
* Added an UI handler next to the existing keymap and operator modal handlers.
  It has an event handling and remove callback, and like operator modal handlers
  will remember the area and region if it is registered at the window level.
* Removed the MESSAGE event.
* Operator cancel and UI handler remove callbacks now get the
  window/area/region restored in the context, like the operator modal and UI
  handler event callbacks.
* Regions now receive MOUSEMOVE events for the mouse going outside of the
  region. This was already happening for areas, but UI buttons are at the region
  level so we need it there.
Issues:
* Tooltips and menus stay open when switching to another window, and button
  highlight doesn't work without moving the mouse first when Blender starts up.
  I tried using some events like Q_FIRSTTIME, WINTHAW, but those don't seem to
  arrive..
* Timeline header buttons seem to be moving one pixel or so sometimes when
  interacting with them.
* Seems not due to this commit, but UI and keymap handlers are leaking. It
  seems that handlers are being added to regions in all screens, also in regions
  of areas that are not visible, but these handlers are not removed. Probably
  there should only be handlers in visible regions?

												Drag and drop 2.5 integration! Finally, slashdot regulars can use
Blender too now! :)
** Drag works as follows:
- drag-able items are defined by the standard interface ui toolkit
- each button can get this feature, via uiButSetDragXXX(but, ...).
  There are calls to define drag-able images, ID blocks, RNA paths, 
  file paths, and so on. By default you drag an icon, exceptionally 
  an ImBuf
- Drag items are registered centrally in the WM, it allows more drag 
  items simultaneous too, but not implemented
** Drop works as follows:
- On mouse release, and if drag items exist in the WM, it converts 
  the mouse event to an EVT_DROP type. This event then gets the full 
  drag info as customdata
- drop regions are defined with WM_dropbox_add(), similar to keymaps 
  you can make a "drop map" this way, which become 'drop map handlers' 
  in the queues.
- next to that the UI kit handles some common button types (like 
  accepting ID or names) to be catching a drop event too.
- Every "drop box" has two callbacks:
  - poll() = check if the event drag data is relevant for this box
  - copy() = fill in custom properties in the dropbox to initialize 
    an operator
- The dropbox handler then calls its standard Operator with its 
  dropbox properties.
** Currently implemented
Drag items:
- ID icons in browse buttons
- ID icons in context menu of properties region
- ID icons in outliner and rna viewer
- FileBrowser icons
- FileBrowser preview images
Drag-able icons are subtly visualized by making them brighter a bit 
on mouse-over. In case the icon is a button or UI element too (most 
cases), the drag-able feature will make the item react to 
mouse-release instead of mouse-press. 
Drop options:
- UI buttons: ID and text buttons (paste name)
- View3d: Object ID drop copies object
- View3d: Material ID drop assigns to object under cursor
- View3d: Image ID drop assigns to object UV texture under cursor
- Sequencer: Path drop will add either Image or Movie strip
- Image window: Path drop will open image
** Drag and drop Notes:
- Dropping into another Blender window (from same application) works 
too. I've added code that passes on mousemoves and clicks to other 
windows, without activating them though. This does make using multi-window
Blender a bit friendler.
- Dropping a file path to an image, is not the same as dropping an 
Image ID... keep this in mind. Sequencer for example wants paths to 
be dropped,  textures in 3d window wants an Image ID.
- Although drop boxes could be defined via Python, I suggest they're 
part of the UI and editor design (= how we want an editor to work), and 
not default offered configurable like keymaps. 
- At the moment only one item can be dragged at a time. This is for 
several reasons.... For one, Blender doesn't have a well defined 
uniform way to define "what is selected" (files, outliner items, etc). 
Secondly there's potential conflicts on what todo when you drop mixed 
drag sets on spots. All undefined stuff... nice for later.
- Example to bypass the above: a collection of images that form a strip, 
should be represented in filewindow as a single sequence anyway. 
This then will fit well and gets handled neatly by design.
- Another option to check is to allow multiple options per drop... it 
could show the operator as a sort of menu, allowing arrow or scrollwheel 
to choose. For time being I'd prefer to try to design a singular drop 
though, just offer only one drop action per data type on given spots.
- What does work already, but a tad slow, is to use a function that 
detects an object (type) under cursor, so a drag item's option can be 
further refined (like drop object on object = parent). (disabled)
** More notes
- Added saving for Region layouts (like split points for toolbar)
- Label buttons now handle mouse over
- File list: added full path entry for drop feature.
- Filesel bugfix: wm_operator_exec() got called there and fully handled, 
while WM event code tried same. Added new OPERATOR_HANDLED flag for this. 
Maybe python needs it too?
- Cocoa: added window move event, so multi-win setups work OK (didnt save).
- Interface_handlers.c: removed win->active
- Severe area copy bug: area handlers were not set to NULL
- Filesel bugfix: next/prev folder list was not copied on area copies
** Leftover todos
- Cocoa windows seem to hang on cases still... needs check
- Cocoa 'draw overlap' swap doesn't work
- Cocoa window loses focus permanently on using Spotlight
  (for these reasons, makefile building has Carbon as default atm)
- ListView templates in UI cannot become dragged yet, needs review... 
it consists of two overlapping UI elements, preventing handling icon clicks.
- There's already Ghost library code to handle dropping from OS 
into Blender window. I've noticed this code is unfinished for Macs, but 
seems to be complete for Windows. Needs test... currently, an external 
drop event will print in console when succesfully delivered to Blender's WM.

UI: don't use operators anymore for handling user interface events, but rather
a special UI handler which makes the code clearer. This UI handler is attached
to the region along with other handlers, and also gets a callback when all
handlers for the region are removed to ensure things are properly cleaned up.
This should fix XXX's in the UI code related to events and context switching.
Most of the changes are in interface_handlers.c, which was renamed from
interface_ops.c, to convert operators to the UI handler. UI code notes:
* uiBeginBlock/uiEndBlock/uiFreeBlocks now takes a context argument, this is
  required to properly cancel things like timers or tooltips when the region
  gets removed.
* UI_add_region_handlers will add the region level UI handlers, to be used
  when adding keymap handlers etc. This replaces the UI keymap.
* When the UI code starts a modal interaction (number sliding, text editing,
  opening a menu, ..), it will add an UI handler at the window level which
  will block events.
Windowmanager changes:
* Added an UI handler next to the existing keymap and operator modal handlers.
  It has an event handling and remove callback, and like operator modal handlers
  will remember the area and region if it is registered at the window level.
* Removed the MESSAGE event.
* Operator cancel and UI handler remove callbacks now get the
  window/area/region restored in the context, like the operator modal and UI
  handler event callbacks.
* Regions now receive MOUSEMOVE events for the mouse going outside of the
  region. This was already happening for areas, but UI buttons are at the region
  level so we need it there.
Issues:
* Tooltips and menus stay open when switching to another window, and button
  highlight doesn't work without moving the mouse first when Blender starts up.
  I tried using some events like Q_FIRSTTIME, WINTHAW, but those don't seem to
  arrive..
* Timeline header buttons seem to be moving one pixel or so sometimes when
  interacting with them.
* Seems not due to this commit, but UI and keymap handlers are leaking. It
  seems that handlers are being added to regions in all screens, also in regions
  of areas that are not visible, but these handlers are not removed. Probably
  there should only be handlers in visible regions?

												Drag and drop 2.5 integration! Finally, slashdot regulars can use
Blender too now! :)
** Drag works as follows:
- drag-able items are defined by the standard interface ui toolkit
- each button can get this feature, via uiButSetDragXXX(but, ...).
  There are calls to define drag-able images, ID blocks, RNA paths, 
  file paths, and so on. By default you drag an icon, exceptionally 
  an ImBuf
- Drag items are registered centrally in the WM, it allows more drag 
  items simultaneous too, but not implemented
** Drop works as follows:
- On mouse release, and if drag items exist in the WM, it converts 
  the mouse event to an EVT_DROP type. This event then gets the full 
  drag info as customdata
- drop regions are defined with WM_dropbox_add(), similar to keymaps 
  you can make a "drop map" this way, which become 'drop map handlers' 
  in the queues.
- next to that the UI kit handles some common button types (like 
  accepting ID or names) to be catching a drop event too.
- Every "drop box" has two callbacks:
  - poll() = check if the event drag data is relevant for this box
  - copy() = fill in custom properties in the dropbox to initialize 
    an operator
- The dropbox handler then calls its standard Operator with its 
  dropbox properties.
** Currently implemented
Drag items:
- ID icons in browse buttons
- ID icons in context menu of properties region
- ID icons in outliner and rna viewer
- FileBrowser icons
- FileBrowser preview images
Drag-able icons are subtly visualized by making them brighter a bit 
on mouse-over. In case the icon is a button or UI element too (most 
cases), the drag-able feature will make the item react to 
mouse-release instead of mouse-press. 
Drop options:
- UI buttons: ID and text buttons (paste name)
- View3d: Object ID drop copies object
- View3d: Material ID drop assigns to object under cursor
- View3d: Image ID drop assigns to object UV texture under cursor
- Sequencer: Path drop will add either Image or Movie strip
- Image window: Path drop will open image
** Drag and drop Notes:
- Dropping into another Blender window (from same application) works 
too. I've added code that passes on mousemoves and clicks to other 
windows, without activating them though. This does make using multi-window
Blender a bit friendler.
- Dropping a file path to an image, is not the same as dropping an 
Image ID... keep this in mind. Sequencer for example wants paths to 
be dropped,  textures in 3d window wants an Image ID.
- Although drop boxes could be defined via Python, I suggest they're 
part of the UI and editor design (= how we want an editor to work), and 
not default offered configurable like keymaps. 
- At the moment only one item can be dragged at a time. This is for 
several reasons.... For one, Blender doesn't have a well defined 
uniform way to define "what is selected" (files, outliner items, etc). 
Secondly there's potential conflicts on what todo when you drop mixed 
drag sets on spots. All undefined stuff... nice for later.
- Example to bypass the above: a collection of images that form a strip, 
should be represented in filewindow as a single sequence anyway. 
This then will fit well and gets handled neatly by design.
- Another option to check is to allow multiple options per drop... it 
could show the operator as a sort of menu, allowing arrow or scrollwheel 
to choose. For time being I'd prefer to try to design a singular drop 
though, just offer only one drop action per data type on given spots.
- What does work already, but a tad slow, is to use a function that 
detects an object (type) under cursor, so a drag item's option can be 
further refined (like drop object on object = parent). (disabled)
** More notes
- Added saving for Region layouts (like split points for toolbar)
- Label buttons now handle mouse over
- File list: added full path entry for drop feature.
- Filesel bugfix: wm_operator_exec() got called there and fully handled, 
while WM event code tried same. Added new OPERATOR_HANDLED flag for this. 
Maybe python needs it too?
- Cocoa: added window move event, so multi-win setups work OK (didnt save).
- Interface_handlers.c: removed win->active
- Severe area copy bug: area handlers were not set to NULL
- Filesel bugfix: next/prev folder list was not copied on area copies
** Leftover todos
- Cocoa windows seem to hang on cases still... needs check
- Cocoa 'draw overlap' swap doesn't work
- Cocoa window loses focus permanently on using Spotlight
  (for these reasons, makefile building has Carbon as default atm)
- ListView templates in UI cannot become dragged yet, needs review... 
it consists of two overlapping UI elements, preventing handling icon clicks.
- There's already Ghost library code to handle dropping from OS 
into Blender window. I've noticed this code is unfinished for Macs, but 
seems to be complete for Windows. Needs test... currently, an external 
drop event will print in console when succesfully delivered to Blender's WM.

												Code holiday commit:
- fix: user pref, window title was reset to 'Blender' on tab usage
- Undo history menu back:
  - name "Undo History"
  - hotkey alt+ctrl+z (alt+apple+z for mac)
  - works like 2.4x, only for global undo, editmode and particle edit.
- Menu scroll
  - for small windows or screens, popup menus now allow to display
    all items, using internal scrolling
  - works with a timer, scrolling 10 items per second when mouse 
    is over the top or bottom arrow
  - if menu is too big to display, it now draws to top or bottom, 
    based on largest available space.
  - also works for hotkey driven pop up menus.
- User pref "DPI" follows widget/layout size
  - widgets & headers now become bigger and smaller, to match 
    'dpi' font sizes. Works well to match UI to monitor size.
  - note that icons can get fuzzy, we need better mipmaps for it

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

- Drag items are registered centrally in the WM, it allows more drag 
  items simultaneous too, but not implemented
** Drop works as follows:
- On mouse release, and if drag items exist in the WM, it converts 
  the mouse event to an EVT_DROP type. This event then gets the full 
  drag info as customdata
- drop regions are defined with WM_dropbox_add(), similar to keymaps 
  you can make a "drop map" this way, which become 'drop map handlers' 
  in the queues.
- next to that the UI kit handles some common button types (like 
  accepting ID or names) to be catching a drop event too.
- Every "drop box" has two callbacks:
  - poll() = check if the event drag data is relevant for this box
  - copy() = fill in custom properties in the dropbox to initialize 
    an operator
- The dropbox handler then calls its standard Operator with its 
  dropbox properties.
** Currently implemented
Drag items:
- ID icons in browse buttons
- ID icons in context menu of properties region
- ID icons in outliner and rna viewer
- FileBrowser icons
- FileBrowser preview images
Drag-able icons are subtly visualized by making them brighter a bit 
on mouse-over. In case the icon is a button or UI element too (most 
cases), the drag-able feature will make the item react to 
mouse-release instead of mouse-press. 
Drop options:
- UI buttons: ID and text buttons (paste name)
- View3d: Object ID drop copies object
- View3d: Material ID drop assigns to object under cursor
- View3d: Image ID drop assigns to object UV texture under cursor
- Sequencer: Path drop will add either Image or Movie strip
- Image window: Path drop will open image
** Drag and drop Notes:
- Dropping into another Blender window (from same application) works 
too. I've added code that passes on mousemoves and clicks to other 
windows, without activating them though. This does make using multi-window
Blender a bit friendler.
- Dropping a file path to an image, is not the same as dropping an 
Image ID... keep this in mind. Sequencer for example wants paths to 
be dropped,  textures in 3d window wants an Image ID.
- Although drop boxes could be defined via Python, I suggest they're 
part of the UI and editor design (= how we want an editor to work), and 
not default offered configurable like keymaps. 
- At the moment only one item can be dragged at a time. This is for 
several reasons.... For one, Blender doesn't have a well defined 
uniform way to define "what is selected" (files, outliner items, etc). 
Secondly there's potential conflicts on what todo when you drop mixed 
drag sets on spots. All undefined stuff... nice for later.
- Example to bypass the above: a collection of images that form a strip, 
should be represented in filewindow as a single sequence anyway. 
This then will fit well and gets handled neatly by design.
- Another option to check is to allow multiple options per drop... it 
could show the operator as a sort of menu, allowing arrow or scrollwheel 
to choose. For time being I'd prefer to try to design a singular drop 
though, just offer only one drop action per data type on given spots.
- What does work already, but a tad slow, is to use a function that 
detects an object (type) under cursor, so a drag item's option can be 
further refined (like drop object on object = parent). (disabled)
** More notes
- Added saving for Region layouts (like split points for toolbar)
- Label buttons now handle mouse over
- File list: added full path entry for drop feature.
- Filesel bugfix: wm_operator_exec() got called there and fully handled, 
while WM event code tried same. Added new OPERATOR_HANDLED flag for this. 
Maybe python needs it too?
- Cocoa: added window move event, so multi-win setups work OK (didnt save).
- Interface_handlers.c: removed win->active
- Severe area copy bug: area handlers were not set to NULL
- Filesel bugfix: next/prev folder list was not copied on area copies
** Leftover todos
- Cocoa windows seem to hang on cases still... needs check
- Cocoa 'draw overlap' swap doesn't work
- Cocoa window loses focus permanently on using Spotlight
  (for these reasons, makefile building has Carbon as default atm)
- ListView templates in UI cannot become dragged yet, needs review... 
it consists of two overlapping UI elements, preventing handling icon clicks.
- There's already Ghost library code to handle dropping from OS 
into Blender window. I've noticed this code is unfinished for Macs, but 
seems to be complete for Windows. Needs test... currently, an external 
drop event will print in console when succesfully delivered to Blender's WM.

UI: don't use operators anymore for handling user interface events, but rather
a special UI handler which makes the code clearer. This UI handler is attached
to the region along with other handlers, and also gets a callback when all
handlers for the region are removed to ensure things are properly cleaned up.
This should fix XXX's in the UI code related to events and context switching.
Most of the changes are in interface_handlers.c, which was renamed from
interface_ops.c, to convert operators to the UI handler. UI code notes:
* uiBeginBlock/uiEndBlock/uiFreeBlocks now takes a context argument, this is
  required to properly cancel things like timers or tooltips when the region
  gets removed.
* UI_add_region_handlers will add the region level UI handlers, to be used
  when adding keymap handlers etc. This replaces the UI keymap.
* When the UI code starts a modal interaction (number sliding, text editing,
  opening a menu, ..), it will add an UI handler at the window level which
  will block events.
Windowmanager changes:
* Added an UI handler next to the existing keymap and operator modal handlers.
  It has an event handling and remove callback, and like operator modal handlers
  will remember the area and region if it is registered at the window level.
* Removed the MESSAGE event.
* Operator cancel and UI handler remove callbacks now get the
  window/area/region restored in the context, like the operator modal and UI
  handler event callbacks.
* Regions now receive MOUSEMOVE events for the mouse going outside of the
  region. This was already happening for areas, but UI buttons are at the region
  level so we need it there.
Issues:
* Tooltips and menus stay open when switching to another window, and button
  highlight doesn't work without moving the mouse first when Blender starts up.
  I tried using some events like Q_FIRSTTIME, WINTHAW, but those don't seem to
  arrive..
* Timeline header buttons seem to be moving one pixel or so sometimes when
  interacting with them.
* Seems not due to this commit, but UI and keymap handlers are leaking. It
  seems that handlers are being added to regions in all screens, also in regions
  of areas that are not visible, but these handlers are not removed. Probably
  there should only be handlers in visible regions?

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

												Drag and drop 2.5 integration! Finally, slashdot regulars can use
Blender too now! :)
** Drag works as follows:
- drag-able items are defined by the standard interface ui toolkit
- each button can get this feature, via uiButSetDragXXX(but, ...).
  There are calls to define drag-able images, ID blocks, RNA paths, 
  file paths, and so on. By default you drag an icon, exceptionally 
  an ImBuf
- Drag items are registered centrally in the WM, it allows more drag 
  items simultaneous too, but not implemented
** Drop works as follows:
- On mouse release, and if drag items exist in the WM, it converts 
  the mouse event to an EVT_DROP type. This event then gets the full 
  drag info as customdata
- drop regions are defined with WM_dropbox_add(), similar to keymaps 
  you can make a "drop map" this way, which become 'drop map handlers' 
  in the queues.
- next to that the UI kit handles some common button types (like 
  accepting ID or names) to be catching a drop event too.
- Every "drop box" has two callbacks:
  - poll() = check if the event drag data is relevant for this box
  - copy() = fill in custom properties in the dropbox to initialize 
    an operator
- The dropbox handler then calls its standard Operator with its 
  dropbox properties.
** Currently implemented
Drag items:
- ID icons in browse buttons
- ID icons in context menu of properties region
- ID icons in outliner and rna viewer
- FileBrowser icons
- FileBrowser preview images
Drag-able icons are subtly visualized by making them brighter a bit 
on mouse-over. In case the icon is a button or UI element too (most 
cases), the drag-able feature will make the item react to 
mouse-release instead of mouse-press. 
Drop options:
- UI buttons: ID and text buttons (paste name)
- View3d: Object ID drop copies object
- View3d: Material ID drop assigns to object under cursor
- View3d: Image ID drop assigns to object UV texture under cursor
- Sequencer: Path drop will add either Image or Movie strip
- Image window: Path drop will open image
** Drag and drop Notes:
- Dropping into another Blender window (from same application) works 
too. I've added code that passes on mousemoves and clicks to other 
windows, without activating them though. This does make using multi-window
Blender a bit friendler.
- Dropping a file path to an image, is not the same as dropping an 
Image ID... keep this in mind. Sequencer for example wants paths to 
be dropped,  textures in 3d window wants an Image ID.
- Although drop boxes could be defined via Python, I suggest they're 
part of the UI and editor design (= how we want an editor to work), and 
not default offered configurable like keymaps. 
- At the moment only one item can be dragged at a time. This is for 
several reasons.... For one, Blender doesn't have a well defined 
uniform way to define "what is selected" (files, outliner items, etc). 
Secondly there's potential conflicts on what todo when you drop mixed 
drag sets on spots. All undefined stuff... nice for later.
- Example to bypass the above: a collection of images that form a strip, 
should be represented in filewindow as a single sequence anyway. 
This then will fit well and gets handled neatly by design.
- Another option to check is to allow multiple options per drop... it 
could show the operator as a sort of menu, allowing arrow or scrollwheel 
to choose. For time being I'd prefer to try to design a singular drop 
though, just offer only one drop action per data type on given spots.
- What does work already, but a tad slow, is to use a function that 
detects an object (type) under cursor, so a drag item's option can be 
further refined (like drop object on object = parent). (disabled)
** More notes
- Added saving for Region layouts (like split points for toolbar)
- Label buttons now handle mouse over
- File list: added full path entry for drop feature.
- Filesel bugfix: wm_operator_exec() got called there and fully handled, 
while WM event code tried same. Added new OPERATOR_HANDLED flag for this. 
Maybe python needs it too?
- Cocoa: added window move event, so multi-win setups work OK (didnt save).
- Interface_handlers.c: removed win->active
- Severe area copy bug: area handlers were not set to NULL
- Filesel bugfix: next/prev folder list was not copied on area copies
** Leftover todos
- Cocoa windows seem to hang on cases still... needs check
- Cocoa 'draw overlap' swap doesn't work
- Cocoa window loses focus permanently on using Spotlight
  (for these reasons, makefile building has Carbon as default atm)
- ListView templates in UI cannot become dragged yet, needs review... 
it consists of two overlapping UI elements, preventing handling icon clicks.
- There's already Ghost library code to handle dropping from OS 
into Blender window. I've noticed this code is unfinished for Macs, but 
seems to be complete for Windows. Needs test... currently, an external 
drop event will print in console when succesfully delivered to Blender's WM.

UI: don't use operators anymore for handling user interface events, but rather
a special UI handler which makes the code clearer. This UI handler is attached
to the region along with other handlers, and also gets a callback when all
handlers for the region are removed to ensure things are properly cleaned up.
This should fix XXX's in the UI code related to events and context switching.
Most of the changes are in interface_handlers.c, which was renamed from
interface_ops.c, to convert operators to the UI handler. UI code notes:
* uiBeginBlock/uiEndBlock/uiFreeBlocks now takes a context argument, this is
  required to properly cancel things like timers or tooltips when the region
  gets removed.
* UI_add_region_handlers will add the region level UI handlers, to be used
  when adding keymap handlers etc. This replaces the UI keymap.
* When the UI code starts a modal interaction (number sliding, text editing,
  opening a menu, ..), it will add an UI handler at the window level which
  will block events.
Windowmanager changes:
* Added an UI handler next to the existing keymap and operator modal handlers.
  It has an event handling and remove callback, and like operator modal handlers
  will remember the area and region if it is registered at the window level.
* Removed the MESSAGE event.
* Operator cancel and UI handler remove callbacks now get the
  window/area/region restored in the context, like the operator modal and UI
  handler event callbacks.
* Regions now receive MOUSEMOVE events for the mouse going outside of the
  region. This was already happening for areas, but UI buttons are at the region
  level so we need it there.
Issues:
* Tooltips and menus stay open when switching to another window, and button
  highlight doesn't work without moving the mouse first when Blender starts up.
  I tried using some events like Q_FIRSTTIME, WINTHAW, but those don't seem to
  arrive..
* Timeline header buttons seem to be moving one pixel or so sometimes when
  interacting with them.
* Seems not due to this commit, but UI and keymap handlers are leaking. It
  seems that handlers are being added to regions in all screens, also in regions
  of areas that are not visible, but these handlers are not removed. Probably
  there should only be handlers in visible regions?

  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

UI: don't use operators anymore for handling user interface events, but rather
a special UI handler which makes the code clearer. This UI handler is attached
to the region along with other handlers, and also gets a callback when all
handlers for the region are removed to ensure things are properly cleaned up.
This should fix XXX's in the UI code related to events and context switching.
Most of the changes are in interface_handlers.c, which was renamed from
interface_ops.c, to convert operators to the UI handler. UI code notes:
* uiBeginBlock/uiEndBlock/uiFreeBlocks now takes a context argument, this is
  required to properly cancel things like timers or tooltips when the region
  gets removed.
* UI_add_region_handlers will add the region level UI handlers, to be used
  when adding keymap handlers etc. This replaces the UI keymap.
* When the UI code starts a modal interaction (number sliding, text editing,
  opening a menu, ..), it will add an UI handler at the window level which
  will block events.
Windowmanager changes:
* Added an UI handler next to the existing keymap and operator modal handlers.
  It has an event handling and remove callback, and like operator modal handlers
  will remember the area and region if it is registered at the window level.
* Removed the MESSAGE event.
* Operator cancel and UI handler remove callbacks now get the
  window/area/region restored in the context, like the operator modal and UI
  handler event callbacks.
* Regions now receive MOUSEMOVE events for the mouse going outside of the
  region. This was already happening for areas, but UI buttons are at the region
  level so we need it there.
Issues:
* Tooltips and menus stay open when switching to another window, and button
  highlight doesn't work without moving the mouse first when Blender starts up.
  I tried using some events like Q_FIRSTTIME, WINTHAW, but those don't seem to
  arrive..
* Timeline header buttons seem to be moving one pixel or so sometimes when
  interacting with them.
* Seems not due to this commit, but UI and keymap handlers are leaking. It
  seems that handlers are being added to regions in all screens, also in regions
  of areas that are not visible, but these handlers are not removed. Probably
  there should only be handlers in visible regions?

  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

												Drag and drop 2.5 integration! Finally, slashdot regulars can use
Blender too now! :)
** Drag works as follows:
- drag-able items are defined by the standard interface ui toolkit
- each button can get this feature, via uiButSetDragXXX(but, ...).
  There are calls to define drag-able images, ID blocks, RNA paths, 
  file paths, and so on. By default you drag an icon, exceptionally 
  an ImBuf
- Drag items are registered centrally in the WM, it allows more drag 
  items simultaneous too, but not implemented
** Drop works as follows:
- On mouse release, and if drag items exist in the WM, it converts 
  the mouse event to an EVT_DROP type. This event then gets the full 
  drag info as customdata
- drop regions are defined with WM_dropbox_add(), similar to keymaps 
  you can make a "drop map" this way, which become 'drop map handlers' 
  in the queues.
- next to that the UI kit handles some common button types (like 
  accepting ID or names) to be catching a drop event too.
- Every "drop box" has two callbacks:
  - poll() = check if the event drag data is relevant for this box
  - copy() = fill in custom properties in the dropbox to initialize 
    an operator
- The dropbox handler then calls its standard Operator with its 
  dropbox properties.
** Currently implemented
Drag items:
- ID icons in browse buttons
- ID icons in context menu of properties region
- ID icons in outliner and rna viewer
- FileBrowser icons
- FileBrowser preview images
Drag-able icons are subtly visualized by making them brighter a bit 
on mouse-over. In case the icon is a button or UI element too (most 
cases), the drag-able feature will make the item react to 
mouse-release instead of mouse-press. 
Drop options:
- UI buttons: ID and text buttons (paste name)
- View3d: Object ID drop copies object
- View3d: Material ID drop assigns to object under cursor
- View3d: Image ID drop assigns to object UV texture under cursor
- Sequencer: Path drop will add either Image or Movie strip
- Image window: Path drop will open image
** Drag and drop Notes:
- Dropping into another Blender window (from same application) works 
too. I've added code that passes on mousemoves and clicks to other 
windows, without activating them though. This does make using multi-window
Blender a bit friendler.
- Dropping a file path to an image, is not the same as dropping an 
Image ID... keep this in mind. Sequencer for example wants paths to 
be dropped,  textures in 3d window wants an Image ID.
- Although drop boxes could be defined via Python, I suggest they're 
part of the UI and editor design (= how we want an editor to work), and 
not default offered configurable like keymaps. 
- At the moment only one item can be dragged at a time. This is for 
several reasons.... For one, Blender doesn't have a well defined 
uniform way to define "what is selected" (files, outliner items, etc). 
Secondly there's potential conflicts on what todo when you drop mixed 
drag sets on spots. All undefined stuff... nice for later.
- Example to bypass the above: a collection of images that form a strip, 
should be represented in filewindow as a single sequence anyway. 
This then will fit well and gets handled neatly by design.
- Another option to check is to allow multiple options per drop... it 
could show the operator as a sort of menu, allowing arrow or scrollwheel 
to choose. For time being I'd prefer to try to design a singular drop 
though, just offer only one drop action per data type on given spots.
- What does work already, but a tad slow, is to use a function that 
detects an object (type) under cursor, so a drag item's option can be 
further refined (like drop object on object = parent). (disabled)
** More notes
- Added saving for Region layouts (like split points for toolbar)
- Label buttons now handle mouse over
- File list: added full path entry for drop feature.
- Filesel bugfix: wm_operator_exec() got called there and fully handled, 
while WM event code tried same. Added new OPERATOR_HANDLED flag for this. 
Maybe python needs it too?
- Cocoa: added window move event, so multi-win setups work OK (didnt save).
- Interface_handlers.c: removed win->active
- Severe area copy bug: area handlers were not set to NULL
- Filesel bugfix: next/prev folder list was not copied on area copies
** Leftover todos
- Cocoa windows seem to hang on cases still... needs check
- Cocoa 'draw overlap' swap doesn't work
- Cocoa window loses focus permanently on using Spotlight
  (for these reasons, makefile building has Carbon as default atm)
- ListView templates in UI cannot become dragged yet, needs review... 
it consists of two overlapping UI elements, preventing handling icon clicks.
- There's already Ghost library code to handle dropping from OS 
into Blender window. I've noticed this code is unfinished for Macs, but 
seems to be complete for Windows. Needs test... currently, an external 
drop event will print in console when succesfully delivered to Blender's WM.

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.

  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking.

UI: don't use operators anymore for handling user interface events, but rather
a special UI handler which makes the code clearer. This UI handler is attached
to the region along with other handlers, and also gets a callback when all
handlers for the region are removed to ensure things are properly cleaned up.
This should fix XXX's in the UI code related to events and context switching.
Most of the changes are in interface_handlers.c, which was renamed from
interface_ops.c, to convert operators to the UI handler. UI code notes:
* uiBeginBlock/uiEndBlock/uiFreeBlocks now takes a context argument, this is
  required to properly cancel things like timers or tooltips when the region
  gets removed.
* UI_add_region_handlers will add the region level UI handlers, to be used
  when adding keymap handlers etc. This replaces the UI keymap.
* When the UI code starts a modal interaction (number sliding, text editing,
  opening a menu, ..), it will add an UI handler at the window level which
  will block events.
Windowmanager changes:
* Added an UI handler next to the existing keymap and operator modal handlers.
  It has an event handling and remove callback, and like operator modal handlers
  will remember the area and region if it is registered at the window level.
* Removed the MESSAGE event.
* Operator cancel and UI handler remove callbacks now get the
  window/area/region restored in the context, like the operator modal and UI
  handler event callbacks.
* Regions now receive MOUSEMOVE events for the mouse going outside of the
  region. This was already happening for areas, but UI buttons are at the region
  level so we need it there.
Issues:
* Tooltips and menus stay open when switching to another window, and button
  highlight doesn't work without moving the mouse first when Blender starts up.
  I tried using some events like Q_FIRSTTIME, WINTHAW, but those don't seem to
  arrive..
* Timeline header buttons seem to be moving one pixel or so sometimes when
  interacting with them.
* Seems not due to this commit, but UI and keymap handlers are leaking. It
  seems that handlers are being added to regions in all screens, also in regions
  of areas that are not visible, but these handlers are not removed. Probably
  there should only be handlers in visible regions?

  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.

* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

UI: don't use operators anymore for handling user interface events, but rather
a special UI handler which makes the code clearer. This UI handler is attached
to the region along with other handlers, and also gets a callback when all
handlers for the region are removed to ensure things are properly cleaned up.
This should fix XXX's in the UI code related to events and context switching.
Most of the changes are in interface_handlers.c, which was renamed from
interface_ops.c, to convert operators to the UI handler. UI code notes:
* uiBeginBlock/uiEndBlock/uiFreeBlocks now takes a context argument, this is
  required to properly cancel things like timers or tooltips when the region
  gets removed.
* UI_add_region_handlers will add the region level UI handlers, to be used
  when adding keymap handlers etc. This replaces the UI keymap.
* When the UI code starts a modal interaction (number sliding, text editing,
  opening a menu, ..), it will add an UI handler at the window level which
  will block events.
Windowmanager changes:
* Added an UI handler next to the existing keymap and operator modal handlers.
  It has an event handling and remove callback, and like operator modal handlers
  will remember the area and region if it is registered at the window level.
* Removed the MESSAGE event.
* Operator cancel and UI handler remove callbacks now get the
  window/area/region restored in the context, like the operator modal and UI
  handler event callbacks.
* Regions now receive MOUSEMOVE events for the mouse going outside of the
  region. This was already happening for areas, but UI buttons are at the region
  level so we need it there.
Issues:
* Tooltips and menus stay open when switching to another window, and button
  highlight doesn't work without moving the mouse first when Blender starts up.
  I tried using some events like Q_FIRSTTIME, WINTHAW, but those don't seem to
  arrive..
* Timeline header buttons seem to be moving one pixel or so sometimes when
  interacting with them.
* Seems not due to this commit, but UI and keymap handlers are leaking. It
  seems that handlers are being added to regions in all screens, also in regions
  of areas that are not visible, but these handlers are not removed. Probably
  there should only be handlers in visible regions?

  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.

UI: don't use operators anymore for handling user interface events, but rather
a special UI handler which makes the code clearer. This UI handler is attached
to the region along with other handlers, and also gets a callback when all
handlers for the region are removed to ensure things are properly cleaned up.
This should fix XXX's in the UI code related to events and context switching.
Most of the changes are in interface_handlers.c, which was renamed from
interface_ops.c, to convert operators to the UI handler. UI code notes:
* uiBeginBlock/uiEndBlock/uiFreeBlocks now takes a context argument, this is
  required to properly cancel things like timers or tooltips when the region
  gets removed.
* UI_add_region_handlers will add the region level UI handlers, to be used
  when adding keymap handlers etc. This replaces the UI keymap.
* When the UI code starts a modal interaction (number sliding, text editing,
  opening a menu, ..), it will add an UI handler at the window level which
  will block events.
Windowmanager changes:
* Added an UI handler next to the existing keymap and operator modal handlers.
  It has an event handling and remove callback, and like operator modal handlers
  will remember the area and region if it is registered at the window level.
* Removed the MESSAGE event.
* Operator cancel and UI handler remove callbacks now get the
  window/area/region restored in the context, like the operator modal and UI
  handler event callbacks.
* Regions now receive MOUSEMOVE events for the mouse going outside of the
  region. This was already happening for areas, but UI buttons are at the region
  level so we need it there.
Issues:
* Tooltips and menus stay open when switching to another window, and button
  highlight doesn't work without moving the mouse first when Blender starts up.
  I tried using some events like Q_FIRSTTIME, WINTHAW, but those don't seem to
  arrive..
* Timeline header buttons seem to be moving one pixel or so sometimes when
  interacting with them.
* Seems not due to this commit, but UI and keymap handlers are leaking. It
  seems that handlers are being added to regions in all screens, also in regions
  of areas that are not visible, but these handlers are not removed. Probably
  there should only be handlers in visible regions?

												Drag and drop 2.5 integration! Finally, slashdot regulars can use
Blender too now! :)
** Drag works as follows:
- drag-able items are defined by the standard interface ui toolkit
- each button can get this feature, via uiButSetDragXXX(but, ...).
  There are calls to define drag-able images, ID blocks, RNA paths, 
  file paths, and so on. By default you drag an icon, exceptionally 
  an ImBuf
- Drag items are registered centrally in the WM, it allows more drag 
  items simultaneous too, but not implemented
** Drop works as follows:
- On mouse release, and if drag items exist in the WM, it converts 
  the mouse event to an EVT_DROP type. This event then gets the full 
  drag info as customdata
- drop regions are defined with WM_dropbox_add(), similar to keymaps 
  you can make a "drop map" this way, which become 'drop map handlers' 
  in the queues.
- next to that the UI kit handles some common button types (like 
  accepting ID or names) to be catching a drop event too.
- Every "drop box" has two callbacks:
  - poll() = check if the event drag data is relevant for this box
  - copy() = fill in custom properties in the dropbox to initialize 
    an operator
- The dropbox handler then calls its standard Operator with its 
  dropbox properties.
** Currently implemented
Drag items:
- ID icons in browse buttons
- ID icons in context menu of properties region
- ID icons in outliner and rna viewer
- FileBrowser icons
- FileBrowser preview images
Drag-able icons are subtly visualized by making them brighter a bit 
on mouse-over. In case the icon is a button or UI element too (most 
cases), the drag-able feature will make the item react to 
mouse-release instead of mouse-press. 
Drop options:
- UI buttons: ID and text buttons (paste name)
- View3d: Object ID drop copies object
- View3d: Material ID drop assigns to object under cursor
- View3d: Image ID drop assigns to object UV texture under cursor
- Sequencer: Path drop will add either Image or Movie strip
- Image window: Path drop will open image
** Drag and drop Notes:
- Dropping into another Blender window (from same application) works 
too. I've added code that passes on mousemoves and clicks to other 
windows, without activating them though. This does make using multi-window
Blender a bit friendler.
- Dropping a file path to an image, is not the same as dropping an 
Image ID... keep this in mind. Sequencer for example wants paths to 
be dropped,  textures in 3d window wants an Image ID.
- Although drop boxes could be defined via Python, I suggest they're 
part of the UI and editor design (= how we want an editor to work), and 
not default offered configurable like keymaps. 
- At the moment only one item can be dragged at a time. This is for 
several reasons.... For one, Blender doesn't have a well defined 
uniform way to define "what is selected" (files, outliner items, etc). 
Secondly there's potential conflicts on what todo when you drop mixed 
drag sets on spots. All undefined stuff... nice for later.
- Example to bypass the above: a collection of images that form a strip, 
should be represented in filewindow as a single sequence anyway. 
This then will fit well and gets handled neatly by design.
- Another option to check is to allow multiple options per drop... it 
could show the operator as a sort of menu, allowing arrow or scrollwheel 
to choose. For time being I'd prefer to try to design a singular drop 
though, just offer only one drop action per data type on given spots.
- What does work already, but a tad slow, is to use a function that 
detects an object (type) under cursor, so a drag item's option can be 
further refined (like drop object on object = parent). (disabled)
** More notes
- Added saving for Region layouts (like split points for toolbar)
- Label buttons now handle mouse over
- File list: added full path entry for drop feature.
- Filesel bugfix: wm_operator_exec() got called there and fully handled, 
while WM event code tried same. Added new OPERATOR_HANDLED flag for this. 
Maybe python needs it too?
- Cocoa: added window move event, so multi-win setups work OK (didnt save).
- Interface_handlers.c: removed win->active
- Severe area copy bug: area handlers were not set to NULL
- Filesel bugfix: next/prev folder list was not copied on area copies
** Leftover todos
- Cocoa windows seem to hang on cases still... needs check
- Cocoa 'draw overlap' swap doesn't work
- Cocoa window loses focus permanently on using Spotlight
  (for these reasons, makefile building has Carbon as default atm)
- ListView templates in UI cannot become dragged yet, needs review... 
it consists of two overlapping UI elements, preventing handling icon clicks.
- There's already Ghost library code to handle dropping from OS 
into Blender window. I've noticed this code is unfinished for Macs, but 
seems to be complete for Windows. Needs test... currently, an external 
drop event will print in console when succesfully delivered to Blender's WM.

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

UI: don't use operators anymore for handling user interface events, but rather
a special UI handler which makes the code clearer. This UI handler is attached
to the region along with other handlers, and also gets a callback when all
handlers for the region are removed to ensure things are properly cleaned up.
This should fix XXX's in the UI code related to events and context switching.
Most of the changes are in interface_handlers.c, which was renamed from
interface_ops.c, to convert operators to the UI handler. UI code notes:
* uiBeginBlock/uiEndBlock/uiFreeBlocks now takes a context argument, this is
  required to properly cancel things like timers or tooltips when the region
  gets removed.
* UI_add_region_handlers will add the region level UI handlers, to be used
  when adding keymap handlers etc. This replaces the UI keymap.
* When the UI code starts a modal interaction (number sliding, text editing,
  opening a menu, ..), it will add an UI handler at the window level which
  will block events.
Windowmanager changes:
* Added an UI handler next to the existing keymap and operator modal handlers.
  It has an event handling and remove callback, and like operator modal handlers
  will remember the area and region if it is registered at the window level.
* Removed the MESSAGE event.
* Operator cancel and UI handler remove callbacks now get the
  window/area/region restored in the context, like the operator modal and UI
  handler event callbacks.
* Regions now receive MOUSEMOVE events for the mouse going outside of the
  region. This was already happening for areas, but UI buttons are at the region
  level so we need it there.
Issues:
* Tooltips and menus stay open when switching to another window, and button
  highlight doesn't work without moving the mouse first when Blender starts up.
  I tried using some events like Q_FIRSTTIME, WINTHAW, but those don't seem to
  arrive..
* Timeline header buttons seem to be moving one pixel or so sometimes when
  interacting with them.
* Seems not due to this commit, but UI and keymap handlers are leaking. It
  seems that handlers are being added to regions in all screens, also in regions
  of areas that are not visible, but these handlers are not removed. Probably
  there should only be handlers in visible regions?

* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to

												Lots of stuff; couldn't commit in parts because of refactor work.
* Changes in interface/ module
This commit brings back the way how buttons/menus work under control
of WM event system. The previous implementation extended usage of
handlers and operators in an interesting but confusing way. Better to
try it first according the design specs. :)
Most obviously:
- modal-handler operators are not stored anymore in regions/areas/windows.
  such modal handlers own their operator, and should remove it themselves.
- removed code to move handlers from one queue to another.
  (needs review with brecht!)
- WM fix: the API call to remove a modal handler got removed. This was a
  dangerous thing anyway, and you should leave that to the event system.
  Now, if a handler modal() call gets a cancel/finish return, it frees 
  itself in event system. WM_event_remove_modal_handler was a confusing 
  call anyway!
Todo:
- allow button-activate to refresh after using button 
- re-enable arrow keys for menus
  (do both after commit)
- review return values of operator callbacks in interface_ops.c
* Fixes in WM system
- Freeing areas/regions/windows, also on quit, now correctly closes 
  running modal handlers
- On starting a modal handler, the handler now stores previous area
  and region context, so they send proper notifiers etc.
* Other fixes
- Area-split operator had bug, wrong minimal size checking. This
  solves error when trying to split a very narrow area.
- removed DNA_USHORT_FIX from screen_types.h, gave warning
- operators didn't get ID name copied when activated, needed for
  later re-use or saving.

												Key Configuration
Keymaps are now saveable and configurable from the user preferences, note
that editing one item in a keymap means the whole keymap is now defined by
the user and will not be updated by Blender, an option for syncing might be
added later. The outliner interface is still there, but I will probably
remove it.
There's actually 3 levels now:
* Default builtin key configuration.
* Key configuration loaded from .py file, for configs like Blender 2.4x
  or other 3D applications.
* Keymaps edited by the user and saved in .B.blend. These can be saved
  to .py files as well to make creating distributable configurations
  easier.
Also, user preferences sections were reorganized a bit, now there is:
Interface, Editing, Input, Files and System.
Implementation notes:
* wmKeyConfig was added which represents a key configuration containing
  keymaps.
* wmKeymapItem was renamed to wmKeyMapItem for consistency with wmKeyMap.
* Modal maps are not wrapped yet.
* User preferences DNA file reading did not support newdataadr() yet,
  added this now for reading keymaps.
* Key configuration related settings are now RNA wrapped.
* is_property_set and is_property_hidden python methods were added.

UI: don't use operators anymore for handling user interface events, but rather
a special UI handler which makes the code clearer. This UI handler is attached
to the region along with other handlers, and also gets a callback when all
handlers for the region are removed to ensure things are properly cleaned up.
This should fix XXX's in the UI code related to events and context switching.
Most of the changes are in interface_handlers.c, which was renamed from
interface_ops.c, to convert operators to the UI handler. UI code notes:
* uiBeginBlock/uiEndBlock/uiFreeBlocks now takes a context argument, this is
  required to properly cancel things like timers or tooltips when the region
  gets removed.
* UI_add_region_handlers will add the region level UI handlers, to be used
  when adding keymap handlers etc. This replaces the UI keymap.
* When the UI code starts a modal interaction (number sliding, text editing,
  opening a menu, ..), it will add an UI handler at the window level which
  will block events.
Windowmanager changes:
* Added an UI handler next to the existing keymap and operator modal handlers.
  It has an event handling and remove callback, and like operator modal handlers
  will remember the area and region if it is registered at the window level.
* Removed the MESSAGE event.
* Operator cancel and UI handler remove callbacks now get the
  window/area/region restored in the context, like the operator modal and UI
  handler event callbacks.
* Regions now receive MOUSEMOVE events for the mouse going outside of the
  region. This was already happening for areas, but UI buttons are at the region
  level so we need it there.
Issues:
* Tooltips and menus stay open when switching to another window, and button
  highlight doesn't work without moving the mouse first when Blender starts up.
  I tried using some events like Q_FIRSTTIME, WINTHAW, but those don't seem to
  arrive..
* Timeline header buttons seem to be moving one pixel or so sometimes when
  interacting with them.
* Seems not due to this commit, but UI and keymap handlers are leaking. It
  seems that handlers are being added to regions in all screens, also in regions
  of areas that are not visible, but these handlers are not removed. Probably
  there should only be handlers in visible regions?

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

UI: don't use operators anymore for handling user interface events, but rather
a special UI handler which makes the code clearer. This UI handler is attached
to the region along with other handlers, and also gets a callback when all
handlers for the region are removed to ensure things are properly cleaned up.
This should fix XXX's in the UI code related to events and context switching.
Most of the changes are in interface_handlers.c, which was renamed from
interface_ops.c, to convert operators to the UI handler. UI code notes:
* uiBeginBlock/uiEndBlock/uiFreeBlocks now takes a context argument, this is
  required to properly cancel things like timers or tooltips when the region
  gets removed.
* UI_add_region_handlers will add the region level UI handlers, to be used
  when adding keymap handlers etc. This replaces the UI keymap.
* When the UI code starts a modal interaction (number sliding, text editing,
  opening a menu, ..), it will add an UI handler at the window level which
  will block events.
Windowmanager changes:
* Added an UI handler next to the existing keymap and operator modal handlers.
  It has an event handling and remove callback, and like operator modal handlers
  will remember the area and region if it is registered at the window level.
* Removed the MESSAGE event.
* Operator cancel and UI handler remove callbacks now get the
  window/area/region restored in the context, like the operator modal and UI
  handler event callbacks.
* Regions now receive MOUSEMOVE events for the mouse going outside of the
  region. This was already happening for areas, but UI buttons are at the region
  level so we need it there.
Issues:
* Tooltips and menus stay open when switching to another window, and button
  highlight doesn't work without moving the mouse first when Blender starts up.
  I tried using some events like Q_FIRSTTIME, WINTHAW, but those don't seem to
  arrive..
* Timeline header buttons seem to be moving one pixel or so sometimes when
  interacting with them.
* Seems not due to this commit, but UI and keymap handlers are leaking. It
  seems that handlers are being added to regions in all screens, also in regions
  of areas that are not visible, but these handlers are not removed. Probably
  there should only be handlers in visible regions?

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

UI: don't use operators anymore for handling user interface events, but rather
a special UI handler which makes the code clearer. This UI handler is attached
to the region along with other handlers, and also gets a callback when all
handlers for the region are removed to ensure things are properly cleaned up.
This should fix XXX's in the UI code related to events and context switching.
Most of the changes are in interface_handlers.c, which was renamed from
interface_ops.c, to convert operators to the UI handler. UI code notes:
* uiBeginBlock/uiEndBlock/uiFreeBlocks now takes a context argument, this is
  required to properly cancel things like timers or tooltips when the region
  gets removed.
* UI_add_region_handlers will add the region level UI handlers, to be used
  when adding keymap handlers etc. This replaces the UI keymap.
* When the UI code starts a modal interaction (number sliding, text editing,
  opening a menu, ..), it will add an UI handler at the window level which
  will block events.
Windowmanager changes:
* Added an UI handler next to the existing keymap and operator modal handlers.
  It has an event handling and remove callback, and like operator modal handlers
  will remember the area and region if it is registered at the window level.
* Removed the MESSAGE event.
* Operator cancel and UI handler remove callbacks now get the
  window/area/region restored in the context, like the operator modal and UI
  handler event callbacks.
* Regions now receive MOUSEMOVE events for the mouse going outside of the
  region. This was already happening for areas, but UI buttons are at the region
  level so we need it there.
Issues:
* Tooltips and menus stay open when switching to another window, and button
  highlight doesn't work without moving the mouse first when Blender starts up.
  I tried using some events like Q_FIRSTTIME, WINTHAW, but those don't seem to
  arrive..
* Timeline header buttons seem to be moving one pixel or so sometimes when
  interacting with them.
* Seems not due to this commit, but UI and keymap handlers are leaking. It
  seems that handlers are being added to regions in all screens, also in regions
  of areas that are not visible, but these handlers are not removed. Probably
  there should only be handlers in visible regions?

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

UI: don't use operators anymore for handling user interface events, but rather
a special UI handler which makes the code clearer. This UI handler is attached
to the region along with other handlers, and also gets a callback when all
handlers for the region are removed to ensure things are properly cleaned up.
This should fix XXX's in the UI code related to events and context switching.
Most of the changes are in interface_handlers.c, which was renamed from
interface_ops.c, to convert operators to the UI handler. UI code notes:
* uiBeginBlock/uiEndBlock/uiFreeBlocks now takes a context argument, this is
  required to properly cancel things like timers or tooltips when the region
  gets removed.
* UI_add_region_handlers will add the region level UI handlers, to be used
  when adding keymap handlers etc. This replaces the UI keymap.
* When the UI code starts a modal interaction (number sliding, text editing,
  opening a menu, ..), it will add an UI handler at the window level which
  will block events.
Windowmanager changes:
* Added an UI handler next to the existing keymap and operator modal handlers.
  It has an event handling and remove callback, and like operator modal handlers
  will remember the area and region if it is registered at the window level.
* Removed the MESSAGE event.
* Operator cancel and UI handler remove callbacks now get the
  window/area/region restored in the context, like the operator modal and UI
  handler event callbacks.
* Regions now receive MOUSEMOVE events for the mouse going outside of the
  region. This was already happening for areas, but UI buttons are at the region
  level so we need it there.
Issues:
* Tooltips and menus stay open when switching to another window, and button
  highlight doesn't work without moving the mouse first when Blender starts up.
  I tried using some events like Q_FIRSTTIME, WINTHAW, but those don't seem to
  arrive..
* Timeline header buttons seem to be moving one pixel or so sometimes when
  interacting with them.
* Seems not due to this commit, but UI and keymap handlers are leaking. It
  seems that handlers are being added to regions in all screens, also in regions
  of areas that are not visible, but these handlers are not removed. Probably
  there should only be handlers in visible regions?

UI: don't use operators anymore for handling user interface events, but rather
a special UI handler which makes the code clearer. This UI handler is attached
to the region along with other handlers, and also gets a callback when all
handlers for the region are removed to ensure things are properly cleaned up.
This should fix XXX's in the UI code related to events and context switching.
Most of the changes are in interface_handlers.c, which was renamed from
interface_ops.c, to convert operators to the UI handler. UI code notes:
* uiBeginBlock/uiEndBlock/uiFreeBlocks now takes a context argument, this is
  required to properly cancel things like timers or tooltips when the region
  gets removed.
* UI_add_region_handlers will add the region level UI handlers, to be used
  when adding keymap handlers etc. This replaces the UI keymap.
* When the UI code starts a modal interaction (number sliding, text editing,
  opening a menu, ..), it will add an UI handler at the window level which
  will block events.
Windowmanager changes:
* Added an UI handler next to the existing keymap and operator modal handlers.
  It has an event handling and remove callback, and like operator modal handlers
  will remember the area and region if it is registered at the window level.
* Removed the MESSAGE event.
* Operator cancel and UI handler remove callbacks now get the
  window/area/region restored in the context, like the operator modal and UI
  handler event callbacks.
* Regions now receive MOUSEMOVE events for the mouse going outside of the
  region. This was already happening for areas, but UI buttons are at the region
  level so we need it there.
Issues:
* Tooltips and menus stay open when switching to another window, and button
  highlight doesn't work without moving the mouse first when Blender starts up.
  I tried using some events like Q_FIRSTTIME, WINTHAW, but those don't seem to
  arrive..
* Timeline header buttons seem to be moving one pixel or so sometimes when
  interacting with them.
* Seems not due to this commit, but UI and keymap handlers are leaking. It
  seems that handlers are being added to regions in all screens, also in regions
  of areas that are not visible, but these handlers are not removed. Probably
  there should only be handlers in visible regions?

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

UI: don't use operators anymore for handling user interface events, but rather
a special UI handler which makes the code clearer. This UI handler is attached
to the region along with other handlers, and also gets a callback when all
handlers for the region are removed to ensure things are properly cleaned up.
This should fix XXX's in the UI code related to events and context switching.
Most of the changes are in interface_handlers.c, which was renamed from
interface_ops.c, to convert operators to the UI handler. UI code notes:
* uiBeginBlock/uiEndBlock/uiFreeBlocks now takes a context argument, this is
  required to properly cancel things like timers or tooltips when the region
  gets removed.
* UI_add_region_handlers will add the region level UI handlers, to be used
  when adding keymap handlers etc. This replaces the UI keymap.
* When the UI code starts a modal interaction (number sliding, text editing,
  opening a menu, ..), it will add an UI handler at the window level which
  will block events.
Windowmanager changes:
* Added an UI handler next to the existing keymap and operator modal handlers.
  It has an event handling and remove callback, and like operator modal handlers
  will remember the area and region if it is registered at the window level.
* Removed the MESSAGE event.
* Operator cancel and UI handler remove callbacks now get the
  window/area/region restored in the context, like the operator modal and UI
  handler event callbacks.
* Regions now receive MOUSEMOVE events for the mouse going outside of the
  region. This was already happening for areas, but UI buttons are at the region
  level so we need it there.
Issues:
* Tooltips and menus stay open when switching to another window, and button
  highlight doesn't work without moving the mouse first when Blender starts up.
  I tried using some events like Q_FIRSTTIME, WINTHAW, but those don't seem to
  arrive..
* Timeline header buttons seem to be moving one pixel or so sometimes when
  interacting with them.
* Seems not due to this commit, but UI and keymap handlers are leaking. It
  seems that handlers are being added to regions in all screens, also in regions
  of areas that are not visible, but these handlers are not removed. Probably
  there should only be handlers in visible regions?

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

  will remember the area and region if it is registered at the window level.
* Removed the MESSAGE event.
* Operator cancel and UI handler remove callbacks now get the
  window/area/region restored in the context, like the operator modal and UI
  handler event callbacks.
* Regions now receive MOUSEMOVE events for the mouse going outside of the
  region. This was already happening for areas, but UI buttons are at the region
  level so we need it there.
Issues:
* Tooltips and menus stay open when switching to another window, and button
  highlight doesn't work without moving the mouse first when Blender starts up.
  I tried using some events like Q_FIRSTTIME, WINTHAW, but those don't seem to
  arrive..
* Timeline header buttons seem to be moving one pixel or so sometimes when
  interacting with them.
* Seems not due to this commit, but UI and keymap handlers are leaking. It
  seems that handlers are being added to regions in all screens, also in regions
  of areas that are not visible, but these handlers are not removed. Probably
  there should only be handlers in visible regions?

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

UI: don't use operators anymore for handling user interface events, but rather
a special UI handler which makes the code clearer. This UI handler is attached
to the region along with other handlers, and also gets a callback when all
handlers for the region are removed to ensure things are properly cleaned up.
This should fix XXX's in the UI code related to events and context switching.
Most of the changes are in interface_handlers.c, which was renamed from
interface_ops.c, to convert operators to the UI handler. UI code notes:
* uiBeginBlock/uiEndBlock/uiFreeBlocks now takes a context argument, this is
  required to properly cancel things like timers or tooltips when the region
  gets removed.
* UI_add_region_handlers will add the region level UI handlers, to be used
  when adding keymap handlers etc. This replaces the UI keymap.
* When the UI code starts a modal interaction (number sliding, text editing,
  opening a menu, ..), it will add an UI handler at the window level which
  will block events.
Windowmanager changes:
* Added an UI handler next to the existing keymap and operator modal handlers.
  It has an event handling and remove callback, and like operator modal handlers
  will remember the area and region if it is registered at the window level.
* Removed the MESSAGE event.
* Operator cancel and UI handler remove callbacks now get the
  window/area/region restored in the context, like the operator modal and UI
  handler event callbacks.

  of areas that are not visible, but these handlers are not removed. Probably
  there should only be handlers in visible regions?

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

UI: don't use operators anymore for handling user interface events, but rather
a special UI handler which makes the code clearer. This UI handler is attached
to the region along with other handlers, and also gets a callback when all
handlers for the region are removed to ensure things are properly cleaned up.
This should fix XXX's in the UI code related to events and context switching.
Most of the changes are in interface_handlers.c, which was renamed from
interface_ops.c, to convert operators to the UI handler. UI code notes:
* uiBeginBlock/uiEndBlock/uiFreeBlocks now takes a context argument, this is
  required to properly cancel things like timers or tooltips when the region
  gets removed.
* UI_add_region_handlers will add the region level UI handlers, to be used
  when adding keymap handlers etc. This replaces the UI keymap.
* When the UI code starts a modal interaction (number sliding, text editing,
  opening a menu, ..), it will add an UI handler at the window level which
  will block events.
Windowmanager changes:
* Added an UI handler next to the existing keymap and operator modal handlers.
  It has an event handling and remove callback, and like operator modal handlers
  will remember the area and region if it is registered at the window level.
* Removed the MESSAGE event.
* Operator cancel and UI handler remove callbacks now get the
  window/area/region restored in the context, like the operator modal and UI
  handler event callbacks.
* Regions now receive MOUSEMOVE events for the mouse going outside of the
  region. This was already happening for areas, but UI buttons are at the region
  level so we need it there.
Issues:
* Tooltips and menus stay open when switching to another window, and button
  highlight doesn't work without moving the mouse first when Blender starts up.
  I tried using some events like Q_FIRSTTIME, WINTHAW, but those don't seem to
  arrive..
* Timeline header buttons seem to be moving one pixel or so sometimes when
  interacting with them.
* Seems not due to this commit, but UI and keymap handlers are leaking. It
  seems that handlers are being added to regions in all screens, also in regions
  of areas that are not visible, but these handlers are not removed. Probably

Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the

  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region

* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full

UI: don't use operators anymore for handling user interface events, but rather
a special UI handler which makes the code clearer. This UI handler is attached
to the region along with other handlers, and also gets a callback when all
handlers for the region are removed to ensure things are properly cleaned up.
This should fix XXX's in the UI code related to events and context switching.
Most of the changes are in interface_handlers.c, which was renamed from
interface_ops.c, to convert operators to the UI handler. UI code notes:
* uiBeginBlock/uiEndBlock/uiFreeBlocks now takes a context argument, this is
  required to properly cancel things like timers or tooltips when the region
  gets removed.
* UI_add_region_handlers will add the region level UI handlers, to be used
  when adding keymap handlers etc. This replaces the UI keymap.
* When the UI code starts a modal interaction (number sliding, text editing,
  opening a menu, ..), it will add an UI handler at the window level which
  will block events.
Windowmanager changes:
* Added an UI handler next to the existing keymap and operator modal handlers.
  It has an event handling and remove callback, and like operator modal handlers
  will remember the area and region if it is registered at the window level.
* Removed the MESSAGE event.
* Operator cancel and UI handler remove callbacks now get the
  window/area/region restored in the context, like the operator modal and UI
  handler event callbacks.
* Regions now receive MOUSEMOVE events for the mouse going outside of the
  region. This was already happening for areas, but UI buttons are at the region
  level so we need it there.
Issues:
* Tooltips and menus stay open when switching to another window, and button
  highlight doesn't work without moving the mouse first when Blender starts up.
  I tried using some events like Q_FIRSTTIME, WINTHAW, but those don't seem to
  arrive..
* Timeline header buttons seem to be moving one pixel or so sometimes when
  interacting with them.
* Seems not due to this commit, but UI and keymap handlers are leaking. It
  seems that handlers are being added to regions in all screens, also in regions
  of areas that are not visible, but these handlers are not removed. Probably
  there should only be handlers in visible regions?

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.

  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

UI: don't use operators anymore for handling user interface events, but rather
a special UI handler which makes the code clearer. This UI handler is attached
to the region along with other handlers, and also gets a callback when all
handlers for the region are removed to ensure things are properly cleaned up.
This should fix XXX's in the UI code related to events and context switching.
Most of the changes are in interface_handlers.c, which was renamed from
interface_ops.c, to convert operators to the UI handler. UI code notes:
* uiBeginBlock/uiEndBlock/uiFreeBlocks now takes a context argument, this is
  required to properly cancel things like timers or tooltips when the region
  gets removed.
* UI_add_region_handlers will add the region level UI handlers, to be used
  when adding keymap handlers etc. This replaces the UI keymap.
* When the UI code starts a modal interaction (number sliding, text editing,
  opening a menu, ..), it will add an UI handler at the window level which
  will block events.
Windowmanager changes:
* Added an UI handler next to the existing keymap and operator modal handlers.
  It has an event handling and remove callback, and like operator modal handlers
  will remember the area and region if it is registered at the window level.
* Removed the MESSAGE event.
* Operator cancel and UI handler remove callbacks now get the
  window/area/region restored in the context, like the operator modal and UI
  handler event callbacks.
* Regions now receive MOUSEMOVE events for the mouse going outside of the
  region. This was already happening for areas, but UI buttons are at the region
  level so we need it there.
Issues:
* Tooltips and menus stay open when switching to another window, and button
  highlight doesn't work without moving the mouse first when Blender starts up.
  I tried using some events like Q_FIRSTTIME, WINTHAW, but those don't seem to
  arrive..
* Timeline header buttons seem to be moving one pixel or so sometimes when
  interacting with them.
* Seems not due to this commit, but UI and keymap handlers are leaking. It
  seems that handlers are being added to regions in all screens, also in regions
  of areas that are not visible, but these handlers are not removed. Probably
  there should only be handlers in visible regions?

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.

												Drag and drop 2.5 integration! Finally, slashdot regulars can use
Blender too now! :)
** Drag works as follows:
- drag-able items are defined by the standard interface ui toolkit
- each button can get this feature, via uiButSetDragXXX(but, ...).
  There are calls to define drag-able images, ID blocks, RNA paths, 
  file paths, and so on. By default you drag an icon, exceptionally 
  an ImBuf
- Drag items are registered centrally in the WM, it allows more drag 
  items simultaneous too, but not implemented
** Drop works as follows:
- On mouse release, and if drag items exist in the WM, it converts 
  the mouse event to an EVT_DROP type. This event then gets the full 
  drag info as customdata
- drop regions are defined with WM_dropbox_add(), similar to keymaps 
  you can make a "drop map" this way, which become 'drop map handlers' 
  in the queues.
- next to that the UI kit handles some common button types (like 
  accepting ID or names) to be catching a drop event too.
- Every "drop box" has two callbacks:
  - poll() = check if the event drag data is relevant for this box
  - copy() = fill in custom properties in the dropbox to initialize 
    an operator
- The dropbox handler then calls its standard Operator with its 
  dropbox properties.
** Currently implemented
Drag items:
- ID icons in browse buttons
- ID icons in context menu of properties region
- ID icons in outliner and rna viewer
- FileBrowser icons
- FileBrowser preview images
Drag-able icons are subtly visualized by making them brighter a bit 
on mouse-over. In case the icon is a button or UI element too (most 
cases), the drag-able feature will make the item react to 
mouse-release instead of mouse-press. 
Drop options:
- UI buttons: ID and text buttons (paste name)
- View3d: Object ID drop copies object
- View3d: Material ID drop assigns to object under cursor
- View3d: Image ID drop assigns to object UV texture under cursor
- Sequencer: Path drop will add either Image or Movie strip
- Image window: Path drop will open image
** Drag and drop Notes:
- Dropping into another Blender window (from same application) works 
too. I've added code that passes on mousemoves and clicks to other 
windows, without activating them though. This does make using multi-window
Blender a bit friendler.
- Dropping a file path to an image, is not the same as dropping an 
Image ID... keep this in mind. Sequencer for example wants paths to 
be dropped,  textures in 3d window wants an Image ID.
- Although drop boxes could be defined via Python, I suggest they're 
part of the UI and editor design (= how we want an editor to work), and 
not default offered configurable like keymaps. 
- At the moment only one item can be dragged at a time. This is for 
several reasons.... For one, Blender doesn't have a well defined 
uniform way to define "what is selected" (files, outliner items, etc). 
Secondly there's potential conflicts on what todo when you drop mixed 
drag sets on spots. All undefined stuff... nice for later.
- Example to bypass the above: a collection of images that form a strip, 
should be represented in filewindow as a single sequence anyway. 
This then will fit well and gets handled neatly by design.
- Another option to check is to allow multiple options per drop... it 
could show the operator as a sort of menu, allowing arrow or scrollwheel 
to choose. For time being I'd prefer to try to design a singular drop 
though, just offer only one drop action per data type on given spots.
- What does work already, but a tad slow, is to use a function that 
detects an object (type) under cursor, so a drag item's option can be 
further refined (like drop object on object = parent). (disabled)
** More notes
- Added saving for Region layouts (like split points for toolbar)
- Label buttons now handle mouse over
- File list: added full path entry for drop feature.
- Filesel bugfix: wm_operator_exec() got called there and fully handled, 
while WM event code tried same. Added new OPERATOR_HANDLED flag for this. 
Maybe python needs it too?
- Cocoa: added window move event, so multi-win setups work OK (didnt save).
- Interface_handlers.c: removed win->active
- Severe area copy bug: area handlers were not set to NULL
- Filesel bugfix: next/prev folder list was not copied on area copies
** Leftover todos
- Cocoa windows seem to hang on cases still... needs check
- Cocoa 'draw overlap' swap doesn't work
- Cocoa window loses focus permanently on using Spotlight
  (for these reasons, makefile building has Carbon as default atm)
- ListView templates in UI cannot become dragged yet, needs review... 
it consists of two overlapping UI elements, preventing handling icon clicks.
- There's already Ghost library code to handle dropping from OS 
into Blender window. I've noticed this code is unfinished for Macs, but 
seems to be complete for Windows. Needs test... currently, an external 
drop event will print in console when succesfully delivered to Blender's WM.

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

UI: don't use operators anymore for handling user interface events, but rather
a special UI handler which makes the code clearer. This UI handler is attached
to the region along with other handlers, and also gets a callback when all
handlers for the region are removed to ensure things are properly cleaned up.
This should fix XXX's in the UI code related to events and context switching.
Most of the changes are in interface_handlers.c, which was renamed from
interface_ops.c, to convert operators to the UI handler. UI code notes:
* uiBeginBlock/uiEndBlock/uiFreeBlocks now takes a context argument, this is
  required to properly cancel things like timers or tooltips when the region
  gets removed.
* UI_add_region_handlers will add the region level UI handlers, to be used
  when adding keymap handlers etc. This replaces the UI keymap.
* When the UI code starts a modal interaction (number sliding, text editing,
  opening a menu, ..), it will add an UI handler at the window level which
  will block events.
Windowmanager changes:
* Added an UI handler next to the existing keymap and operator modal handlers.
  It has an event handling and remove callback, and like operator modal handlers
  will remember the area and region if it is registered at the window level.
* Removed the MESSAGE event.
* Operator cancel and UI handler remove callbacks now get the
  window/area/region restored in the context, like the operator modal and UI
  handler event callbacks.
* Regions now receive MOUSEMOVE events for the mouse going outside of the
  region. This was already happening for areas, but UI buttons are at the region
  level so we need it there.
Issues:
* Tooltips and menus stay open when switching to another window, and button
  highlight doesn't work without moving the mouse first when Blender starts up.
  I tried using some events like Q_FIRSTTIME, WINTHAW, but those don't seem to
  arrive..
* Timeline header buttons seem to be moving one pixel or so sometimes when
  interacting with them.
* Seems not due to this commit, but UI and keymap handlers are leaking. It
  seems that handlers are being added to regions in all screens, also in regions
  of areas that are not visible, but these handlers are not removed. Probably
  there should only be handlers in visible regions?

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

UI: don't use operators anymore for handling user interface events, but rather
a special UI handler which makes the code clearer. This UI handler is attached
to the region along with other handlers, and also gets a callback when all
handlers for the region are removed to ensure things are properly cleaned up.
This should fix XXX's in the UI code related to events and context switching.
Most of the changes are in interface_handlers.c, which was renamed from
interface_ops.c, to convert operators to the UI handler. UI code notes:
* uiBeginBlock/uiEndBlock/uiFreeBlocks now takes a context argument, this is
  required to properly cancel things like timers or tooltips when the region
  gets removed.
* UI_add_region_handlers will add the region level UI handlers, to be used
  when adding keymap handlers etc. This replaces the UI keymap.
* When the UI code starts a modal interaction (number sliding, text editing,
  opening a menu, ..), it will add an UI handler at the window level which
  will block events.
Windowmanager changes:
* Added an UI handler next to the existing keymap and operator modal handlers.
  It has an event handling and remove callback, and like operator modal handlers
  will remember the area and region if it is registered at the window level.
* Removed the MESSAGE event.
* Operator cancel and UI handler remove callbacks now get the
  window/area/region restored in the context, like the operator modal and UI
  handler event callbacks.
* Regions now receive MOUSEMOVE events for the mouse going outside of the
  region. This was already happening for areas, but UI buttons are at the region
  level so we need it there.
Issues:
* Tooltips and menus stay open when switching to another window, and button
  highlight doesn't work without moving the mouse first when Blender starts up.
  I tried using some events like Q_FIRSTTIME, WINTHAW, but those don't seem to
  arrive..
* Timeline header buttons seem to be moving one pixel or so sometimes when
  interacting with them.
* Seems not due to this commit, but UI and keymap handlers are leaking. It
  seems that handlers are being added to regions in all screens, also in regions
  of areas that are not visible, but these handlers are not removed. Probably
  there should only be handlers in visible regions?

Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.

UI: don't use operators anymore for handling user interface events, but rather
a special UI handler which makes the code clearer. This UI handler is attached
to the region along with other handlers, and also gets a callback when all
handlers for the region are removed to ensure things are properly cleaned up.
This should fix XXX's in the UI code related to events and context switching.
Most of the changes are in interface_handlers.c, which was renamed from
interface_ops.c, to convert operators to the UI handler. UI code notes:
* uiBeginBlock/uiEndBlock/uiFreeBlocks now takes a context argument, this is
  required to properly cancel things like timers or tooltips when the region
  gets removed.
* UI_add_region_handlers will add the region level UI handlers, to be used
  when adding keymap handlers etc. This replaces the UI keymap.
* When the UI code starts a modal interaction (number sliding, text editing,
  opening a menu, ..), it will add an UI handler at the window level which
  will block events.
Windowmanager changes:
* Added an UI handler next to the existing keymap and operator modal handlers.
  It has an event handling and remove callback, and like operator modal handlers
  will remember the area and region if it is registered at the window level.
* Removed the MESSAGE event.
* Operator cancel and UI handler remove callbacks now get the
  window/area/region restored in the context, like the operator modal and UI
  handler event callbacks.
* Regions now receive MOUSEMOVE events for the mouse going outside of the
  region. This was already happening for areas, but UI buttons are at the region
  level so we need it there.
Issues:
* Tooltips and menus stay open when switching to another window, and button
  highlight doesn't work without moving the mouse first when Blender starts up.
  I tried using some events like Q_FIRSTTIME, WINTHAW, but those don't seem to
  arrive..
* Timeline header buttons seem to be moving one pixel or so sometimes when
  interacting with them.
* Seems not due to this commit, but UI and keymap handlers are leaking. It
  seems that handlers are being added to regions in all screens, also in regions
  of areas that are not visible, but these handlers are not removed. Probably
  there should only be handlers in visible regions?

* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need

UI: don't use operators anymore for handling user interface events, but rather
a special UI handler which makes the code clearer. This UI handler is attached
to the region along with other handlers, and also gets a callback when all
handlers for the region are removed to ensure things are properly cleaned up.
This should fix XXX's in the UI code related to events and context switching.
Most of the changes are in interface_handlers.c, which was renamed from
interface_ops.c, to convert operators to the UI handler. UI code notes:
* uiBeginBlock/uiEndBlock/uiFreeBlocks now takes a context argument, this is
  required to properly cancel things like timers or tooltips when the region
  gets removed.
* UI_add_region_handlers will add the region level UI handlers, to be used
  when adding keymap handlers etc. This replaces the UI keymap.
* When the UI code starts a modal interaction (number sliding, text editing,
  opening a menu, ..), it will add an UI handler at the window level which
  will block events.
Windowmanager changes:
* Added an UI handler next to the existing keymap and operator modal handlers.
  It has an event handling and remove callback, and like operator modal handlers
  will remember the area and region if it is registered at the window level.
* Removed the MESSAGE event.
* Operator cancel and UI handler remove callbacks now get the
  window/area/region restored in the context, like the operator modal and UI
  handler event callbacks.
* Regions now receive MOUSEMOVE events for the mouse going outside of the
  region. This was already happening for areas, but UI buttons are at the region
  level so we need it there.
Issues:
* Tooltips and menus stay open when switching to another window, and button
  highlight doesn't work without moving the mouse first when Blender starts up.
  I tried using some events like Q_FIRSTTIME, WINTHAW, but those don't seem to
  arrive..
* Timeline header buttons seem to be moving one pixel or so sometimes when
  interacting with them.
* Seems not due to this commit, but UI and keymap handlers are leaking. It
  seems that handlers are being added to regions in all screens, also in regions
  of areas that are not visible, but these handlers are not removed. Probably
  there should only be handlers in visible regions?

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu

UI: don't use operators anymore for handling user interface events, but rather
a special UI handler which makes the code clearer. This UI handler is attached
to the region along with other handlers, and also gets a callback when all
handlers for the region are removed to ensure things are properly cleaned up.
This should fix XXX's in the UI code related to events and context switching.
Most of the changes are in interface_handlers.c, which was renamed from
interface_ops.c, to convert operators to the UI handler. UI code notes:
* uiBeginBlock/uiEndBlock/uiFreeBlocks now takes a context argument, this is
  required to properly cancel things like timers or tooltips when the region
  gets removed.
* UI_add_region_handlers will add the region level UI handlers, to be used
  when adding keymap handlers etc. This replaces the UI keymap.
* When the UI code starts a modal interaction (number sliding, text editing,
  opening a menu, ..), it will add an UI handler at the window level which
  will block events.
Windowmanager changes:
* Added an UI handler next to the existing keymap and operator modal handlers.
  It has an event handling and remove callback, and like operator modal handlers
  will remember the area and region if it is registered at the window level.
* Removed the MESSAGE event.
* Operator cancel and UI handler remove callbacks now get the
  window/area/region restored in the context, like the operator modal and UI
  handler event callbacks.
* Regions now receive MOUSEMOVE events for the mouse going outside of the
  region. This was already happening for areas, but UI buttons are at the region
  level so we need it there.
Issues:
* Tooltips and menus stay open when switching to another window, and button
  highlight doesn't work without moving the mouse first when Blender starts up.
  I tried using some events like Q_FIRSTTIME, WINTHAW, but those don't seem to
  arrive..
* Timeline header buttons seem to be moving one pixel or so sometimes when
  interacting with them.
* Seems not due to this commit, but UI and keymap handlers are leaking. It
  seems that handlers are being added to regions in all screens, also in regions
  of areas that are not visible, but these handlers are not removed. Probably
  there should only be handlers in visible regions?

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

												This commit frees list ui items from their dependencies to Panel, and hence from all the limitations this implied (mostly, the "only one list per panel" one).
It introduces a new (py-extendable and registrable) RNA type, UIList (roughly similar to Panel one), which currently contains only "standard" list's scroll pos and size (but may be expended to include e.g. some filtering data, etc.). This now makes lists completely independent from Panels!
This UIList has a draw_item callback which allows to customize items' drawing from python, that all addons can now use. Incidentally, this also greatly simplifies the C code of this widget, as we do not code any "special case" here anymore!
To make all this work, other changes were also necessary:
* Now all buttons (uiBut struct) have a 'custom_data' void pointer, used currently to store the uiList struct associated with a given uiLayoutListBox.
* DynamicPaintSurface now exposes a new bool, use_color_preview (readonly), saying whether that surface has some 3D view preview data or not.
* UILayout class has now four new (static) functions, to get the actual icon of any RNA object (important e.g. with materials or textures), and to get an enum item's UI name, description and icon.
* UILayout's label() func now takes an optional 'icon_value' integer parameter, which if not zero will override the 'icon' one (mandatory to use "custom" icons as generated for material/texture/... previews).
  Note: not sure whether we should add that one to all UILayout's prop funcs?
Note: will update addons using template list asap.

  Note: not sure whether we should add that one to all UILayout's prop funcs?
Note: will update addons using template list asap.

												This commit frees list ui items from their dependencies to Panel, and hence from all the limitations this implied (mostly, the "only one list per panel" one).
It introduces a new (py-extendable and registrable) RNA type, UIList (roughly similar to Panel one), which currently contains only "standard" list's scroll pos and size (but may be expended to include e.g. some filtering data, etc.). This now makes lists completely independent from Panels!
This UIList has a draw_item callback which allows to customize items' drawing from python, that all addons can now use. Incidentally, this also greatly simplifies the C code of this widget, as we do not code any "special case" here anymore!
To make all this work, other changes were also necessary:
* Now all buttons (uiBut struct) have a 'custom_data' void pointer, used currently to store the uiList struct associated with a given uiLayoutListBox.
* DynamicPaintSurface now exposes a new bool, use_color_preview (readonly), saying whether that surface has some 3D view preview data or not.
* UILayout class has now four new (static) functions, to get the actual icon of any RNA object (important e.g. with materials or textures), and to get an enum item's UI name, description and icon.
* UILayout's label() func now takes an optional 'icon_value' integer parameter, which if not zero will override the 'icon' one (mandatory to use "custom" icons as generated for material/texture/... previews).

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

UI: don't use operators anymore for handling user interface events, but rather
a special UI handler which makes the code clearer. This UI handler is attached
to the region along with other handlers, and also gets a callback when all
handlers for the region are removed to ensure things are properly cleaned up.
This should fix XXX's in the UI code related to events and context switching.
Most of the changes are in interface_handlers.c, which was renamed from
interface_ops.c, to convert operators to the UI handler. UI code notes:
* uiBeginBlock/uiEndBlock/uiFreeBlocks now takes a context argument, this is
  required to properly cancel things like timers or tooltips when the region
  gets removed.
* UI_add_region_handlers will add the region level UI handlers, to be used
  when adding keymap handlers etc. This replaces the UI keymap.
* When the UI code starts a modal interaction (number sliding, text editing,
  opening a menu, ..), it will add an UI handler at the window level which
  will block events.
Windowmanager changes:
* Added an UI handler next to the existing keymap and operator modal handlers.
  It has an event handling and remove callback, and like operator modal handlers
  will remember the area and region if it is registered at the window level.
* Removed the MESSAGE event.
* Operator cancel and UI handler remove callbacks now get the
  window/area/region restored in the context, like the operator modal and UI
  handler event callbacks.
* Regions now receive MOUSEMOVE events for the mouse going outside of the
  region. This was already happening for areas, but UI buttons are at the region
  level so we need it there.
Issues:
* Tooltips and menus stay open when switching to another window, and button
  highlight doesn't work without moving the mouse first when Blender starts up.
  I tried using some events like Q_FIRSTTIME, WINTHAW, but those don't seem to
  arrive..
* Timeline header buttons seem to be moving one pixel or so sometimes when
  interacting with them.
* Seems not due to this commit, but UI and keymap handlers are leaking. It
  seems that handlers are being added to regions in all screens, also in regions
  of areas that are not visible, but these handlers are not removed. Probably
  there should only be handlers in visible regions?

												2.5: UI & Menus
* Cleaned up UI_interface.h a bit, and added some comments to
  organize things a bit and indicate what should be used when.
* uiMenu* functions can now be used to create menus for headers
  too, this is done with a uiDefMenuBut, which takes a pointer
  to a uiMenuCreateFunc, that will then call uiMenu* functions.
* Renamed uiMenuBegin/End to uiPupMenuBegin/End, as these are
  specific to making popup menus. Will convert the other
  conformation popup menu functions to use this too so we can
  remove some code.
* Extended uiMenu functions, now there is is also:
  BooleanO, FloatO, BooleanR, EnumR, LevelEnumR, Separator.
* Converted image window headers to use uiMenu functions, simplifies
  menu code further here. Did not remove the uiDefMenu functions as
  they are used in sequencer/view3d in some places now (will fix).
* Also tried to simplify and fix bounds computation a bit better
  for popup menus. It tried to find out in advance what the size
  of the menu was but this is difficult with keymap strings in
  there, now uiPopupBoundsBlock can figure this out afterwards and
  ensure the popup is within the window bounds. Will convert some
  other functions to use this too.

  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

UI: don't use operators anymore for handling user interface events, but rather
a special UI handler which makes the code clearer. This UI handler is attached
to the region along with other handlers, and also gets a callback when all
handlers for the region are removed to ensure things are properly cleaned up.
This should fix XXX's in the UI code related to events and context switching.
Most of the changes are in interface_handlers.c, which was renamed from
interface_ops.c, to convert operators to the UI handler. UI code notes:
* uiBeginBlock/uiEndBlock/uiFreeBlocks now takes a context argument, this is
  required to properly cancel things like timers or tooltips when the region
  gets removed.
* UI_add_region_handlers will add the region level UI handlers, to be used
  when adding keymap handlers etc. This replaces the UI keymap.
* When the UI code starts a modal interaction (number sliding, text editing,
  opening a menu, ..), it will add an UI handler at the window level which
  will block events.
Windowmanager changes:
* Added an UI handler next to the existing keymap and operator modal handlers.
  It has an event handling and remove callback, and like operator modal handlers
  will remember the area and region if it is registered at the window level.
* Removed the MESSAGE event.
* Operator cancel and UI handler remove callbacks now get the
  window/area/region restored in the context, like the operator modal and UI
  handler event callbacks.
* Regions now receive MOUSEMOVE events for the mouse going outside of the
  region. This was already happening for areas, but UI buttons are at the region
  level so we need it there.
Issues:
* Tooltips and menus stay open when switching to another window, and button
  highlight doesn't work without moving the mouse first when Blender starts up.
  I tried using some events like Q_FIRSTTIME, WINTHAW, but those don't seem to
  arrive..
* Timeline header buttons seem to be moving one pixel or so sometimes when
  interacting with them.
* Seems not due to this commit, but UI and keymap handlers are leaking. It
  seems that handlers are being added to regions in all screens, also in regions
  of areas that are not visible, but these handlers are not removed. Probably
  there should only be handlers in visible regions?

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

UI: don't use operators anymore for handling user interface events, but rather
a special UI handler which makes the code clearer. This UI handler is attached
to the region along with other handlers, and also gets a callback when all
handlers for the region are removed to ensure things are properly cleaned up.
This should fix XXX's in the UI code related to events and context switching.
Most of the changes are in interface_handlers.c, which was renamed from
interface_ops.c, to convert operators to the UI handler. UI code notes:
* uiBeginBlock/uiEndBlock/uiFreeBlocks now takes a context argument, this is
  required to properly cancel things like timers or tooltips when the region
  gets removed.
* UI_add_region_handlers will add the region level UI handlers, to be used
  when adding keymap handlers etc. This replaces the UI keymap.
* When the UI code starts a modal interaction (number sliding, text editing,
  opening a menu, ..), it will add an UI handler at the window level which
  will block events.
Windowmanager changes:
* Added an UI handler next to the existing keymap and operator modal handlers.
  It has an event handling and remove callback, and like operator modal handlers
  will remember the area and region if it is registered at the window level.
* Removed the MESSAGE event.
* Operator cancel and UI handler remove callbacks now get the
  window/area/region restored in the context, like the operator modal and UI
  handler event callbacks.
* Regions now receive MOUSEMOVE events for the mouse going outside of the
  region. This was already happening for areas, but UI buttons are at the region
  level so we need it there.
Issues:
* Tooltips and menus stay open when switching to another window, and button
  highlight doesn't work without moving the mouse first when Blender starts up.
  I tried using some events like Q_FIRSTTIME, WINTHAW, but those don't seem to
  arrive..
* Timeline header buttons seem to be moving one pixel or so sometimes when
  interacting with them.
* Seems not due to this commit, but UI and keymap handlers are leaking. It
  seems that handlers are being added to regions in all screens, also in regions
  of areas that are not visible, but these handlers are not removed. Probably
  there should only be handlers in visible regions?

												2.5: UI & Menus
* Cleaned up UI_interface.h a bit, and added some comments to
  organize things a bit and indicate what should be used when.
* uiMenu* functions can now be used to create menus for headers
  too, this is done with a uiDefMenuBut, which takes a pointer
  to a uiMenuCreateFunc, that will then call uiMenu* functions.
* Renamed uiMenuBegin/End to uiPupMenuBegin/End, as these are
  specific to making popup menus. Will convert the other
  conformation popup menu functions to use this too so we can
  remove some code.
* Extended uiMenu functions, now there is is also:
  BooleanO, FloatO, BooleanR, EnumR, LevelEnumR, Separator.
* Converted image window headers to use uiMenu functions, simplifies
  menu code further here. Did not remove the uiDefMenu functions as
  they are used in sequencer/view3d in some places now (will fix).
* Also tried to simplify and fix bounds computation a bit better
  for popup menus. It tried to find out in advance what the size
  of the menu was but this is difficult with keymap strings in
  there, now uiPopupBoundsBlock can figure this out afterwards and
  ensure the popup is within the window bounds. Will convert some
  other functions to use this too.

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

UI: don't use operators anymore for handling user interface events, but rather
a special UI handler which makes the code clearer. This UI handler is attached
to the region along with other handlers, and also gets a callback when all
handlers for the region are removed to ensure things are properly cleaned up.
This should fix XXX's in the UI code related to events and context switching.
Most of the changes are in interface_handlers.c, which was renamed from
interface_ops.c, to convert operators to the UI handler. UI code notes:
* uiBeginBlock/uiEndBlock/uiFreeBlocks now takes a context argument, this is
  required to properly cancel things like timers or tooltips when the region
  gets removed.
* UI_add_region_handlers will add the region level UI handlers, to be used
  when adding keymap handlers etc. This replaces the UI keymap.
* When the UI code starts a modal interaction (number sliding, text editing,
  opening a menu, ..), it will add an UI handler at the window level which
  will block events.
Windowmanager changes:
* Added an UI handler next to the existing keymap and operator modal handlers.
  It has an event handling and remove callback, and like operator modal handlers
  will remember the area and region if it is registered at the window level.
* Removed the MESSAGE event.
* Operator cancel and UI handler remove callbacks now get the
  window/area/region restored in the context, like the operator modal and UI
  handler event callbacks.
* Regions now receive MOUSEMOVE events for the mouse going outside of the
  region. This was already happening for areas, but UI buttons are at the region
  level so we need it there.
Issues:
* Tooltips and menus stay open when switching to another window, and button
  highlight doesn't work without moving the mouse first when Blender starts up.
  I tried using some events like Q_FIRSTTIME, WINTHAW, but those don't seem to
  arrive..
* Timeline header buttons seem to be moving one pixel or so sometimes when
  interacting with them.
* Seems not due to this commit, but UI and keymap handlers are leaking. It
  seems that handlers are being added to regions in all screens, also in regions
  of areas that are not visible, but these handlers are not removed. Probably
  there should only be handlers in visible regions?

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

UI: don't use operators anymore for handling user interface events, but rather
a special UI handler which makes the code clearer. This UI handler is attached
to the region along with other handlers, and also gets a callback when all
handlers for the region are removed to ensure things are properly cleaned up.
This should fix XXX's in the UI code related to events and context switching.
Most of the changes are in interface_handlers.c, which was renamed from
interface_ops.c, to convert operators to the UI handler. UI code notes:
* uiBeginBlock/uiEndBlock/uiFreeBlocks now takes a context argument, this is
  required to properly cancel things like timers or tooltips when the region
  gets removed.
* UI_add_region_handlers will add the region level UI handlers, to be used
  when adding keymap handlers etc. This replaces the UI keymap.
* When the UI code starts a modal interaction (number sliding, text editing,
  opening a menu, ..), it will add an UI handler at the window level which
  will block events.
Windowmanager changes:
* Added an UI handler next to the existing keymap and operator modal handlers.
  It has an event handling and remove callback, and like operator modal handlers
  will remember the area and region if it is registered at the window level.
* Removed the MESSAGE event.
* Operator cancel and UI handler remove callbacks now get the
  window/area/region restored in the context, like the operator modal and UI
  handler event callbacks.
* Regions now receive MOUSEMOVE events for the mouse going outside of the
  region. This was already happening for areas, but UI buttons are at the region
  level so we need it there.
Issues:
* Tooltips and menus stay open when switching to another window, and button
  highlight doesn't work without moving the mouse first when Blender starts up.
  I tried using some events like Q_FIRSTTIME, WINTHAW, but those don't seem to
  arrive..
* Timeline header buttons seem to be moving one pixel or so sometimes when
  interacting with them.
* Seems not due to this commit, but UI and keymap handlers are leaking. It
  seems that handlers are being added to regions in all screens, also in regions
  of areas that are not visible, but these handlers are not removed. Probably
  there should only be handlers in visible regions?

* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted

UI: don't use operators anymore for handling user interface events, but rather
a special UI handler which makes the code clearer. This UI handler is attached
to the region along with other handlers, and also gets a callback when all
handlers for the region are removed to ensure things are properly cleaned up.
This should fix XXX's in the UI code related to events and context switching.
Most of the changes are in interface_handlers.c, which was renamed from
interface_ops.c, to convert operators to the UI handler. UI code notes:
* uiBeginBlock/uiEndBlock/uiFreeBlocks now takes a context argument, this is
  required to properly cancel things like timers or tooltips when the region
  gets removed.
* UI_add_region_handlers will add the region level UI handlers, to be used
  when adding keymap handlers etc. This replaces the UI keymap.
* When the UI code starts a modal interaction (number sliding, text editing,
  opening a menu, ..), it will add an UI handler at the window level which
  will block events.
Windowmanager changes:
* Added an UI handler next to the existing keymap and operator modal handlers.
  It has an event handling and remove callback, and like operator modal handlers
  will remember the area and region if it is registered at the window level.
* Removed the MESSAGE event.
* Operator cancel and UI handler remove callbacks now get the
  window/area/region restored in the context, like the operator modal and UI
  handler event callbacks.
* Regions now receive MOUSEMOVE events for the mouse going outside of the
  region. This was already happening for areas, but UI buttons are at the region
  level so we need it there.
Issues:
* Tooltips and menus stay open when switching to another window, and button
  highlight doesn't work without moving the mouse first when Blender starts up.
  I tried using some events like Q_FIRSTTIME, WINTHAW, but those don't seem to
  arrive..
* Timeline header buttons seem to be moving one pixel or so sometimes when
  interacting with them.
* Seems not due to this commit, but UI and keymap handlers are leaking. It
  seems that handlers are being added to regions in all screens, also in regions
  of areas that are not visible, but these handlers are not removed. Probably
  there should only be handlers in visible regions?

												Code holiday commit:
- fix: user pref, window title was reset to 'Blender' on tab usage
- Undo history menu back:
  - name "Undo History"
  - hotkey alt+ctrl+z (alt+apple+z for mac)
  - works like 2.4x, only for global undo, editmode and particle edit.
- Menu scroll
  - for small windows or screens, popup menus now allow to display
    all items, using internal scrolling
  - works with a timer, scrolling 10 items per second when mouse 
    is over the top or bottom arrow
  - if menu is too big to display, it now draws to top or bottom, 
    based on largest available space.
  - also works for hotkey driven pop up menus.
- User pref "DPI" follows widget/layout size
  - widgets & headers now become bigger and smaller, to match 
    'dpi' font sizes. Works well to match UI to monitor size.
  - note that icons can get fuzzy, we need better mipmaps for it

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

UI: don't use operators anymore for handling user interface events, but rather
a special UI handler which makes the code clearer. This UI handler is attached
to the region along with other handlers, and also gets a callback when all
handlers for the region are removed to ensure things are properly cleaned up.
This should fix XXX's in the UI code related to events and context switching.
Most of the changes are in interface_handlers.c, which was renamed from
interface_ops.c, to convert operators to the UI handler. UI code notes:
* uiBeginBlock/uiEndBlock/uiFreeBlocks now takes a context argument, this is
  required to properly cancel things like timers or tooltips when the region
  gets removed.
* UI_add_region_handlers will add the region level UI handlers, to be used
  when adding keymap handlers etc. This replaces the UI keymap.
* When the UI code starts a modal interaction (number sliding, text editing,
  opening a menu, ..), it will add an UI handler at the window level which
  will block events.
Windowmanager changes:
* Added an UI handler next to the existing keymap and operator modal handlers.
  It has an event handling and remove callback, and like operator modal handlers
  will remember the area and region if it is registered at the window level.
* Removed the MESSAGE event.
* Operator cancel and UI handler remove callbacks now get the
  window/area/region restored in the context, like the operator modal and UI
  handler event callbacks.
* Regions now receive MOUSEMOVE events for the mouse going outside of the
  region. This was already happening for areas, but UI buttons are at the region
  level so we need it there.
Issues:
* Tooltips and menus stay open when switching to another window, and button
  highlight doesn't work without moving the mouse first when Blender starts up.
  I tried using some events like Q_FIRSTTIME, WINTHAW, but those don't seem to
  arrive..
* Timeline header buttons seem to be moving one pixel or so sometimes when
  interacting with them.
* Seems not due to this commit, but UI and keymap handlers are leaking. It
  seems that handlers are being added to regions in all screens, also in regions
  of areas that are not visible, but these handlers are not removed. Probably
  there should only be handlers in visible regions?

UI: don't use operators anymore for handling user interface events, but rather
a special UI handler which makes the code clearer. This UI handler is attached
to the region along with other handlers, and also gets a callback when all
handlers for the region are removed to ensure things are properly cleaned up.
This should fix XXX's in the UI code related to events and context switching.
Most of the changes are in interface_handlers.c, which was renamed from
interface_ops.c, to convert operators to the UI handler. UI code notes:
* uiBeginBlock/uiEndBlock/uiFreeBlocks now takes a context argument, this is
  required to properly cancel things like timers or tooltips when the region
  gets removed.
* UI_add_region_handlers will add the region level UI handlers, to be used
  when adding keymap handlers etc. This replaces the UI keymap.
* When the UI code starts a modal interaction (number sliding, text editing,
  opening a menu, ..), it will add an UI handler at the window level which
  will block events.
Windowmanager changes:
* Added an UI handler next to the existing keymap and operator modal handlers.
  It has an event handling and remove callback, and like operator modal handlers
  will remember the area and region if it is registered at the window level.
* Removed the MESSAGE event.
* Operator cancel and UI handler remove callbacks now get the
  window/area/region restored in the context, like the operator modal and UI
  handler event callbacks.
* Regions now receive MOUSEMOVE events for the mouse going outside of the
  region. This was already happening for areas, but UI buttons are at the region
  level so we need it there.
Issues:
* Tooltips and menus stay open when switching to another window, and button
  highlight doesn't work without moving the mouse first when Blender starts up.
  I tried using some events like Q_FIRSTTIME, WINTHAW, but those don't seem to
  arrive..
* Timeline header buttons seem to be moving one pixel or so sometimes when
  interacting with them.
* Seems not due to this commit, but UI and keymap handlers are leaking. It
  seems that handlers are being added to regions in all screens, also in regions
  of areas that are not visible, but these handlers are not removed. Probably
  there should only be handlers in visible regions?

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated

UI: don't use operators anymore for handling user interface events, but rather
a special UI handler which makes the code clearer. This UI handler is attached
to the region along with other handlers, and also gets a callback when all
handlers for the region are removed to ensure things are properly cleaned up.
This should fix XXX's in the UI code related to events and context switching.
Most of the changes are in interface_handlers.c, which was renamed from
interface_ops.c, to convert operators to the UI handler. UI code notes:
* uiBeginBlock/uiEndBlock/uiFreeBlocks now takes a context argument, this is
  required to properly cancel things like timers or tooltips when the region
  gets removed.
* UI_add_region_handlers will add the region level UI handlers, to be used
  when adding keymap handlers etc. This replaces the UI keymap.
* When the UI code starts a modal interaction (number sliding, text editing,
  opening a menu, ..), it will add an UI handler at the window level which
  will block events.
Windowmanager changes:
* Added an UI handler next to the existing keymap and operator modal handlers.
  It has an event handling and remove callback, and like operator modal handlers
  will remember the area and region if it is registered at the window level.
* Removed the MESSAGE event.
* Operator cancel and UI handler remove callbacks now get the
  window/area/region restored in the context, like the operator modal and UI
  handler event callbacks.
* Regions now receive MOUSEMOVE events for the mouse going outside of the
  region. This was already happening for areas, but UI buttons are at the region
  level so we need it there.
Issues:
* Tooltips and menus stay open when switching to another window, and button
  highlight doesn't work without moving the mouse first when Blender starts up.
  I tried using some events like Q_FIRSTTIME, WINTHAW, but those don't seem to
  arrive..
* Timeline header buttons seem to be moving one pixel or so sometimes when
  interacting with them.
* Seems not due to this commit, but UI and keymap handlers are leaking. It
  seems that handlers are being added to regions in all screens, also in regions
  of areas that are not visible, but these handlers are not removed. Probably
  there should only be handlers in visible regions?

* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need

* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

UI: don't use operators anymore for handling user interface events, but rather
a special UI handler which makes the code clearer. This UI handler is attached
to the region along with other handlers, and also gets a callback when all
handlers for the region are removed to ensure things are properly cleaned up.
This should fix XXX's in the UI code related to events and context switching.
Most of the changes are in interface_handlers.c, which was renamed from
interface_ops.c, to convert operators to the UI handler. UI code notes:
* uiBeginBlock/uiEndBlock/uiFreeBlocks now takes a context argument, this is
  required to properly cancel things like timers or tooltips when the region
  gets removed.
* UI_add_region_handlers will add the region level UI handlers, to be used
  when adding keymap handlers etc. This replaces the UI keymap.
* When the UI code starts a modal interaction (number sliding, text editing,
  opening a menu, ..), it will add an UI handler at the window level which
  will block events.
Windowmanager changes:
* Added an UI handler next to the existing keymap and operator modal handlers.
  It has an event handling and remove callback, and like operator modal handlers
  will remember the area and region if it is registered at the window level.
* Removed the MESSAGE event.
* Operator cancel and UI handler remove callbacks now get the
  window/area/region restored in the context, like the operator modal and UI
  handler event callbacks.
* Regions now receive MOUSEMOVE events for the mouse going outside of the
  region. This was already happening for areas, but UI buttons are at the region
  level so we need it there.
Issues:
* Tooltips and menus stay open when switching to another window, and button
  highlight doesn't work without moving the mouse first when Blender starts up.
  I tried using some events like Q_FIRSTTIME, WINTHAW, but those don't seem to
  arrive..
* Timeline header buttons seem to be moving one pixel or so sometimes when
  interacting with them.
* Seems not due to this commit, but UI and keymap handlers are leaking. It
  seems that handlers are being added to regions in all screens, also in regions
  of areas that are not visible, but these handlers are not removed. Probably
  there should only be handlers in visible regions?

  gets removed.
* UI_add_region_handlers will add the region level UI handlers, to be used
  when adding keymap handlers etc. This replaces the UI keymap.
* When the UI code starts a modal interaction (number sliding, text editing,
  opening a menu, ..), it will add an UI handler at the window level which
  will block events.
Windowmanager changes:
* Added an UI handler next to the existing keymap and operator modal handlers.
  It has an event handling and remove callback, and like operator modal handlers
  will remember the area and region if it is registered at the window level.
* Removed the MESSAGE event.
* Operator cancel and UI handler remove callbacks now get the
  window/area/region restored in the context, like the operator modal and UI
  handler event callbacks.
* Regions now receive MOUSEMOVE events for the mouse going outside of the
  region. This was already happening for areas, but UI buttons are at the region
  level so we need it there.
Issues:
* Tooltips and menus stay open when switching to another window, and button
  highlight doesn't work without moving the mouse first when Blender starts up.
  I tried using some events like Q_FIRSTTIME, WINTHAW, but those don't seem to
  arrive..
* Timeline header buttons seem to be moving one pixel or so sometimes when
  interacting with them.
* Seems not due to this commit, but UI and keymap handlers are leaking. It
  seems that handlers are being added to regions in all screens, also in regions
  of areas that are not visible, but these handlers are not removed. Probably
  there should only be handlers in visible regions?

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

UI: don't use operators anymore for handling user interface events, but rather
a special UI handler which makes the code clearer. This UI handler is attached
to the region along with other handlers, and also gets a callback when all
handlers for the region are removed to ensure things are properly cleaned up.
This should fix XXX's in the UI code related to events and context switching.
Most of the changes are in interface_handlers.c, which was renamed from
interface_ops.c, to convert operators to the UI handler. UI code notes:

  required to properly cancel things like timers or tooltips when the region

UI: don't use operators anymore for handling user interface events, but rather
a special UI handler which makes the code clearer. This UI handler is attached
to the region along with other handlers, and also gets a callback when all
handlers for the region are removed to ensure things are properly cleaned up.
This should fix XXX's in the UI code related to events and context switching.
Most of the changes are in interface_handlers.c, which was renamed from
interface_ops.c, to convert operators to the UI handler. UI code notes:
* uiBeginBlock/uiEndBlock/uiFreeBlocks now takes a context argument, this is
  required to properly cancel things like timers or tooltips when the region
  gets removed.
* UI_add_region_handlers will add the region level UI handlers, to be used
  when adding keymap handlers etc. This replaces the UI keymap.
* When the UI code starts a modal interaction (number sliding, text editing,
  opening a menu, ..), it will add an UI handler at the window level which
  will block events.
Windowmanager changes:
* Added an UI handler next to the existing keymap and operator modal handlers.
  It has an event handling and remove callback, and like operator modal handlers
  will remember the area and region if it is registered at the window level.
* Removed the MESSAGE event.
* Operator cancel and UI handler remove callbacks now get the
  window/area/region restored in the context, like the operator modal and UI
  handler event callbacks.
* Regions now receive MOUSEMOVE events for the mouse going outside of the
  region. This was already happening for areas, but UI buttons are at the region
  level so we need it there.
Issues:
* Tooltips and menus stay open when switching to another window, and button
  highlight doesn't work without moving the mouse first when Blender starts up.
  I tried using some events like Q_FIRSTTIME, WINTHAW, but those don't seem to
  arrive..
* Timeline header buttons seem to be moving one pixel or so sometimes when
  interacting with them.
* Seems not due to this commit, but UI and keymap handlers are leaking. It
  seems that handlers are being added to regions in all screens, also in regions
  of areas that are not visible, but these handlers are not removed. Probably
  there should only be handlers in visible regions?

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

UI: don't use operators anymore for handling user interface events, but rather
a special UI handler which makes the code clearer. This UI handler is attached
to the region along with other handlers, and also gets a callback when all
handlers for the region are removed to ensure things are properly cleaned up.
This should fix XXX's in the UI code related to events and context switching.
Most of the changes are in interface_handlers.c, which was renamed from
interface_ops.c, to convert operators to the UI handler. UI code notes:
* uiBeginBlock/uiEndBlock/uiFreeBlocks now takes a context argument, this is
  required to properly cancel things like timers or tooltips when the region
  gets removed.
* UI_add_region_handlers will add the region level UI handlers, to be used
  when adding keymap handlers etc. This replaces the UI keymap.
* When the UI code starts a modal interaction (number sliding, text editing,
  opening a menu, ..), it will add an UI handler at the window level which
  will block events.
Windowmanager changes:
* Added an UI handler next to the existing keymap and operator modal handlers.
  It has an event handling and remove callback, and like operator modal handlers
  will remember the area and region if it is registered at the window level.
* Removed the MESSAGE event.
* Operator cancel and UI handler remove callbacks now get the
  window/area/region restored in the context, like the operator modal and UI
  handler event callbacks.
* Regions now receive MOUSEMOVE events for the mouse going outside of the
  region. This was already happening for areas, but UI buttons are at the region
  level so we need it there.
Issues:
* Tooltips and menus stay open when switching to another window, and button
  highlight doesn't work without moving the mouse first when Blender starts up.
  I tried using some events like Q_FIRSTTIME, WINTHAW, but those don't seem to
  arrive..
* Timeline header buttons seem to be moving one pixel or so sometimes when
  interacting with them.
* Seems not due to this commit, but UI and keymap handlers are leaking. It
  seems that handlers are being added to regions in all screens, also in regions
  of areas that are not visible, but these handlers are not removed. Probably
  there should only be handlers in visible regions?

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

UI: don't use operators anymore for handling user interface events, but rather
a special UI handler which makes the code clearer. This UI handler is attached
to the region along with other handlers, and also gets a callback when all
handlers for the region are removed to ensure things are properly cleaned up.
This should fix XXX's in the UI code related to events and context switching.
Most of the changes are in interface_handlers.c, which was renamed from
interface_ops.c, to convert operators to the UI handler. UI code notes:
* uiBeginBlock/uiEndBlock/uiFreeBlocks now takes a context argument, this is
  required to properly cancel things like timers or tooltips when the region
  gets removed.
* UI_add_region_handlers will add the region level UI handlers, to be used
  when adding keymap handlers etc. This replaces the UI keymap.
* When the UI code starts a modal interaction (number sliding, text editing,
  opening a menu, ..), it will add an UI handler at the window level which
  will block events.
Windowmanager changes:
* Added an UI handler next to the existing keymap and operator modal handlers.
  It has an event handling and remove callback, and like operator modal handlers
  will remember the area and region if it is registered at the window level.
* Removed the MESSAGE event.
* Operator cancel and UI handler remove callbacks now get the
  window/area/region restored in the context, like the operator modal and UI
  handler event callbacks.
* Regions now receive MOUSEMOVE events for the mouse going outside of the
  region. This was already happening for areas, but UI buttons are at the region
  level so we need it there.
Issues:
* Tooltips and menus stay open when switching to another window, and button
  highlight doesn't work without moving the mouse first when Blender starts up.
  I tried using some events like Q_FIRSTTIME, WINTHAW, but those don't seem to
  arrive..
* Timeline header buttons seem to be moving one pixel or so sometimes when
  interacting with them.
* Seems not due to this commit, but UI and keymap handlers are leaking. It
  seems that handlers are being added to regions in all screens, also in regions
  of areas that are not visible, but these handlers are not removed. Probably
  there should only be handlers in visible regions?

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.

												2.5: UI & Menus
* Cleaned up UI_interface.h a bit, and added some comments to
  organize things a bit and indicate what should be used when.
* uiMenu* functions can now be used to create menus for headers
  too, this is done with a uiDefMenuBut, which takes a pointer
  to a uiMenuCreateFunc, that will then call uiMenu* functions.
* Renamed uiMenuBegin/End to uiPupMenuBegin/End, as these are
  specific to making popup menus. Will convert the other
  conformation popup menu functions to use this too so we can
  remove some code.
* Extended uiMenu functions, now there is is also:
  BooleanO, FloatO, BooleanR, EnumR, LevelEnumR, Separator.
* Converted image window headers to use uiMenu functions, simplifies
  menu code further here. Did not remove the uiDefMenu functions as
  they are used in sequencer/view3d in some places now (will fix).
* Also tried to simplify and fix bounds computation a bit better
  for popup menus. It tried to find out in advance what the size
  of the menu was but this is difficult with keymap strings in
  there, now uiPopupBoundsBlock can figure this out afterwards and
  ensure the popup is within the window bounds. Will convert some
  other functions to use this too.

  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

UI: don't use operators anymore for handling user interface events, but rather
a special UI handler which makes the code clearer. This UI handler is attached
to the region along with other handlers, and also gets a callback when all
handlers for the region are removed to ensure things are properly cleaned up.
This should fix XXX's in the UI code related to events and context switching.
Most of the changes are in interface_handlers.c, which was renamed from
interface_ops.c, to convert operators to the UI handler. UI code notes:
* uiBeginBlock/uiEndBlock/uiFreeBlocks now takes a context argument, this is
  required to properly cancel things like timers or tooltips when the region
  gets removed.
* UI_add_region_handlers will add the region level UI handlers, to be used
  when adding keymap handlers etc. This replaces the UI keymap.
* When the UI code starts a modal interaction (number sliding, text editing,
  opening a menu, ..), it will add an UI handler at the window level which
  will block events.
Windowmanager changes:
* Added an UI handler next to the existing keymap and operator modal handlers.
  It has an event handling and remove callback, and like operator modal handlers
  will remember the area and region if it is registered at the window level.
* Removed the MESSAGE event.
* Operator cancel and UI handler remove callbacks now get the
  window/area/region restored in the context, like the operator modal and UI
  handler event callbacks.
* Regions now receive MOUSEMOVE events for the mouse going outside of the
  region. This was already happening for areas, but UI buttons are at the region
  level so we need it there.
Issues:
* Tooltips and menus stay open when switching to another window, and button
  highlight doesn't work without moving the mouse first when Blender starts up.
  I tried using some events like Q_FIRSTTIME, WINTHAW, but those don't seem to
  arrive..
* Timeline header buttons seem to be moving one pixel or so sometimes when
  interacting with them.
* Seems not due to this commit, but UI and keymap handlers are leaking. It
  seems that handlers are being added to regions in all screens, also in regions
  of areas that are not visible, but these handlers are not removed. Probably
  there should only be handlers in visible regions?

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.

  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.

* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

UI: don't use operators anymore for handling user interface events, but rather
a special UI handler which makes the code clearer. This UI handler is attached
to the region along with other handlers, and also gets a callback when all
handlers for the region are removed to ensure things are properly cleaned up.
This should fix XXX's in the UI code related to events and context switching.
Most of the changes are in interface_handlers.c, which was renamed from
interface_ops.c, to convert operators to the UI handler. UI code notes:
* uiBeginBlock/uiEndBlock/uiFreeBlocks now takes a context argument, this is
  required to properly cancel things like timers or tooltips when the region
  gets removed.
* UI_add_region_handlers will add the region level UI handlers, to be used
  when adding keymap handlers etc. This replaces the UI keymap.
* When the UI code starts a modal interaction (number sliding, text editing,
  opening a menu, ..), it will add an UI handler at the window level which
  will block events.
Windowmanager changes:
* Added an UI handler next to the existing keymap and operator modal handlers.
  It has an event handling and remove callback, and like operator modal handlers
  will remember the area and region if it is registered at the window level.
* Removed the MESSAGE event.
* Operator cancel and UI handler remove callbacks now get the
  window/area/region restored in the context, like the operator modal and UI
  handler event callbacks.
* Regions now receive MOUSEMOVE events for the mouse going outside of the
  region. This was already happening for areas, but UI buttons are at the region
  level so we need it there.
Issues:
* Tooltips and menus stay open when switching to another window, and button
  highlight doesn't work without moving the mouse first when Blender starts up.
  I tried using some events like Q_FIRSTTIME, WINTHAW, but those don't seem to
  arrive..
* Timeline header buttons seem to be moving one pixel or so sometimes when
  interacting with them.
* Seems not due to this commit, but UI and keymap handlers are leaking. It
  seems that handlers are being added to regions in all screens, also in regions
  of areas that are not visible, but these handlers are not removed. Probably
  there should only be handlers in visible regions?

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

												2.5: UI & Menus
* Cleaned up UI_interface.h a bit, and added some comments to
  organize things a bit and indicate what should be used when.
* uiMenu* functions can now be used to create menus for headers
  too, this is done with a uiDefMenuBut, which takes a pointer
  to a uiMenuCreateFunc, that will then call uiMenu* functions.
* Renamed uiMenuBegin/End to uiPupMenuBegin/End, as these are
  specific to making popup menus. Will convert the other
  conformation popup menu functions to use this too so we can
  remove some code.
* Extended uiMenu functions, now there is is also:
  BooleanO, FloatO, BooleanR, EnumR, LevelEnumR, Separator.
* Converted image window headers to use uiMenu functions, simplifies
  menu code further here. Did not remove the uiDefMenu functions as
  they are used in sequencer/view3d in some places now (will fix).
* Also tried to simplify and fix bounds computation a bit better
  for popup menus. It tried to find out in advance what the size
  of the menu was but this is difficult with keymap strings in
  there, now uiPopupBoundsBlock can figure this out afterwards and
  ensure the popup is within the window bounds. Will convert some
  other functions to use this too.

UI: don't use operators anymore for handling user interface events, but rather
a special UI handler which makes the code clearer. This UI handler is attached
to the region along with other handlers, and also gets a callback when all
handlers for the region are removed to ensure things are properly cleaned up.
This should fix XXX's in the UI code related to events and context switching.
Most of the changes are in interface_handlers.c, which was renamed from
interface_ops.c, to convert operators to the UI handler. UI code notes:
* uiBeginBlock/uiEndBlock/uiFreeBlocks now takes a context argument, this is
  required to properly cancel things like timers or tooltips when the region
  gets removed.
* UI_add_region_handlers will add the region level UI handlers, to be used
  when adding keymap handlers etc. This replaces the UI keymap.
* When the UI code starts a modal interaction (number sliding, text editing,
  opening a menu, ..), it will add an UI handler at the window level which
  will block events.
Windowmanager changes:
* Added an UI handler next to the existing keymap and operator modal handlers.
  It has an event handling and remove callback, and like operator modal handlers
  will remember the area and region if it is registered at the window level.
* Removed the MESSAGE event.
* Operator cancel and UI handler remove callbacks now get the
  window/area/region restored in the context, like the operator modal and UI
  handler event callbacks.
* Regions now receive MOUSEMOVE events for the mouse going outside of the
  region. This was already happening for areas, but UI buttons are at the region
  level so we need it there.
Issues:
* Tooltips and menus stay open when switching to another window, and button
  highlight doesn't work without moving the mouse first when Blender starts up.
  I tried using some events like Q_FIRSTTIME, WINTHAW, but those don't seem to
  arrive..
* Timeline header buttons seem to be moving one pixel or so sometimes when
  interacting with them.
* Seems not due to this commit, but UI and keymap handlers are leaking. It
  seems that handlers are being added to regions in all screens, also in regions
  of areas that are not visible, but these handlers are not removed. Probably
  there should only be handlers in visible regions?

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

UI: don't use operators anymore for handling user interface events, but rather
a special UI handler which makes the code clearer. This UI handler is attached
to the region along with other handlers, and also gets a callback when all
handlers for the region are removed to ensure things are properly cleaned up.
This should fix XXX's in the UI code related to events and context switching.
Most of the changes are in interface_handlers.c, which was renamed from
interface_ops.c, to convert operators to the UI handler. UI code notes:
* uiBeginBlock/uiEndBlock/uiFreeBlocks now takes a context argument, this is
  required to properly cancel things like timers or tooltips when the region
  gets removed.
* UI_add_region_handlers will add the region level UI handlers, to be used
  when adding keymap handlers etc. This replaces the UI keymap.
* When the UI code starts a modal interaction (number sliding, text editing,
  opening a menu, ..), it will add an UI handler at the window level which
  will block events.
Windowmanager changes:
* Added an UI handler next to the existing keymap and operator modal handlers.
  It has an event handling and remove callback, and like operator modal handlers
  will remember the area and region if it is registered at the window level.
* Removed the MESSAGE event.
* Operator cancel and UI handler remove callbacks now get the
  window/area/region restored in the context, like the operator modal and UI
  handler event callbacks.
* Regions now receive MOUSEMOVE events for the mouse going outside of the
  region. This was already happening for areas, but UI buttons are at the region
  level so we need it there.
Issues:
* Tooltips and menus stay open when switching to another window, and button
  highlight doesn't work without moving the mouse first when Blender starts up.
  I tried using some events like Q_FIRSTTIME, WINTHAW, but those don't seem to
  arrive..
* Timeline header buttons seem to be moving one pixel or so sometimes when
  interacting with them.
* Seems not due to this commit, but UI and keymap handlers are leaking. It
  seems that handlers are being added to regions in all screens, also in regions
  of areas that are not visible, but these handlers are not removed. Probably
  there should only be handlers in visible regions?

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

UI: don't use operators anymore for handling user interface events, but rather
a special UI handler which makes the code clearer. This UI handler is attached
to the region along with other handlers, and also gets a callback when all
handlers for the region are removed to ensure things are properly cleaned up.
This should fix XXX's in the UI code related to events and context switching.
Most of the changes are in interface_handlers.c, which was renamed from
interface_ops.c, to convert operators to the UI handler. UI code notes:
* uiBeginBlock/uiEndBlock/uiFreeBlocks now takes a context argument, this is
  required to properly cancel things like timers or tooltips when the region
  gets removed.
* UI_add_region_handlers will add the region level UI handlers, to be used
  when adding keymap handlers etc. This replaces the UI keymap.
* When the UI code starts a modal interaction (number sliding, text editing,
  opening a menu, ..), it will add an UI handler at the window level which
  will block events.
Windowmanager changes:
* Added an UI handler next to the existing keymap and operator modal handlers.
  It has an event handling and remove callback, and like operator modal handlers
  will remember the area and region if it is registered at the window level.
* Removed the MESSAGE event.
* Operator cancel and UI handler remove callbacks now get the
  window/area/region restored in the context, like the operator modal and UI
  handler event callbacks.
* Regions now receive MOUSEMOVE events for the mouse going outside of the
  region. This was already happening for areas, but UI buttons are at the region
  level so we need it there.
Issues:
* Tooltips and menus stay open when switching to another window, and button
  highlight doesn't work without moving the mouse first when Blender starts up.
  I tried using some events like Q_FIRSTTIME, WINTHAW, but those don't seem to
  arrive..
* Timeline header buttons seem to be moving one pixel or so sometimes when
  interacting with them.
* Seems not due to this commit, but UI and keymap handlers are leaking. It
  seems that handlers are being added to regions in all screens, also in regions
  of areas that are not visible, but these handlers are not removed. Probably
  there should only be handlers in visible regions?

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.

UI: don't use operators anymore for handling user interface events, but rather
a special UI handler which makes the code clearer. This UI handler is attached
to the region along with other handlers, and also gets a callback when all
handlers for the region are removed to ensure things are properly cleaned up.
This should fix XXX's in the UI code related to events and context switching.
Most of the changes are in interface_handlers.c, which was renamed from
interface_ops.c, to convert operators to the UI handler. UI code notes:
* uiBeginBlock/uiEndBlock/uiFreeBlocks now takes a context argument, this is
  required to properly cancel things like timers or tooltips when the region
  gets removed.
* UI_add_region_handlers will add the region level UI handlers, to be used
  when adding keymap handlers etc. This replaces the UI keymap.
* When the UI code starts a modal interaction (number sliding, text editing,
  opening a menu, ..), it will add an UI handler at the window level which
  will block events.
Windowmanager changes:
* Added an UI handler next to the existing keymap and operator modal handlers.
  It has an event handling and remove callback, and like operator modal handlers
  will remember the area and region if it is registered at the window level.
* Removed the MESSAGE event.
* Operator cancel and UI handler remove callbacks now get the
  window/area/region restored in the context, like the operator modal and UI
  handler event callbacks.
* Regions now receive MOUSEMOVE events for the mouse going outside of the
  region. This was already happening for areas, but UI buttons are at the region
  level so we need it there.
Issues:
* Tooltips and menus stay open when switching to another window, and button
  highlight doesn't work without moving the mouse first when Blender starts up.
  I tried using some events like Q_FIRSTTIME, WINTHAW, but those don't seem to
  arrive..
* Timeline header buttons seem to be moving one pixel or so sometimes when
  interacting with them.
* Seems not due to this commit, but UI and keymap handlers are leaking. It
  seems that handlers are being added to regions in all screens, also in regions
  of areas that are not visible, but these handlers are not removed. Probably
  there should only be handlers in visible regions?

												2.5: UI & Menus
* Cleaned up UI_interface.h a bit, and added some comments to
  organize things a bit and indicate what should be used when.
* uiMenu* functions can now be used to create menus for headers
  too, this is done with a uiDefMenuBut, which takes a pointer
  to a uiMenuCreateFunc, that will then call uiMenu* functions.
* Renamed uiMenuBegin/End to uiPupMenuBegin/End, as these are
  specific to making popup menus. Will convert the other
  conformation popup menu functions to use this too so we can
  remove some code.
* Extended uiMenu functions, now there is is also:
  BooleanO, FloatO, BooleanR, EnumR, LevelEnumR, Separator.
* Converted image window headers to use uiMenu functions, simplifies
  menu code further here. Did not remove the uiDefMenu functions as
  they are used in sequencer/view3d in some places now (will fix).
* Also tried to simplify and fix bounds computation a bit better
  for popup menus. It tried to find out in advance what the size
  of the menu was but this is difficult with keymap strings in
  there, now uiPopupBoundsBlock can figure this out afterwards and
  ensure the popup is within the window bounds. Will convert some
  other functions to use this too.

												UI: Layout Engine
* Buttons are now created first, and after that the layout is computed.
  This means the layout engine now works at button level, and makes it
  easier to write templates. Otherwise you had to store all info and
  create the buttons later.
* Added interface_templates.c as a separate file to put templates in.
  These can contain regular buttons, and can be put in a Free layout,
  which means you can specify manual coordinates, but still get nested
  correct inside other layouts.
* API was changed to allow better nesting. Previously items were added
  in the last added layout specifier, i.e. one level up in the layout
  hierarchy. This doesn't work well in always, so now when creating things
  like rows or columns it always returns a layout which you have to add
  the items in. All py scripts were updated to follow this.
* Computing the layout now goes in two passes, first estimating the
  required width/height of all nested layouts, and then in the second
  pass using the results of that to decide on the actual locations.
* Enum and array buttons now follow the direction of the layout, i.e.
  they are vertical or horizontal depending if they are in a column or row.
* Color properties now get a color picker, and only get the additional
  RGB sliders with Expand=True.
* File/directory string properties now get a button next to them for
  opening the file browse, though this is not implemented yet.
* Layout items can now be aligned, set align=True when creating a column,
  row, etc.
* Buttons now get a minimum width of one icon (avoids squashing icon
  buttons).
* Moved some more space variables into Style.

												2.5: UI & Menus
* Cleaned up UI_interface.h a bit, and added some comments to
  organize things a bit and indicate what should be used when.
* uiMenu* functions can now be used to create menus for headers
  too, this is done with a uiDefMenuBut, which takes a pointer
  to a uiMenuCreateFunc, that will then call uiMenu* functions.
* Renamed uiMenuBegin/End to uiPupMenuBegin/End, as these are
  specific to making popup menus. Will convert the other
  conformation popup menu functions to use this too so we can
  remove some code.
* Extended uiMenu functions, now there is is also:
  BooleanO, FloatO, BooleanR, EnumR, LevelEnumR, Separator.
* Converted image window headers to use uiMenu functions, simplifies
  menu code further here. Did not remove the uiDefMenu functions as
  they are used in sequencer/view3d in some places now (will fix).
* Also tried to simplify and fix bounds computation a bit better
  for popup menus. It tried to find out in advance what the size
  of the menu was but this is difficult with keymap strings in
  there, now uiPopupBoundsBlock can figure this out afterwards and
  ensure the popup is within the window bounds. Will convert some
  other functions to use this too.

UI: don't use operators anymore for handling user interface events, but rather
a special UI handler which makes the code clearer. This UI handler is attached
to the region along with other handlers, and also gets a callback when all
handlers for the region are removed to ensure things are properly cleaned up.
This should fix XXX's in the UI code related to events and context switching.
Most of the changes are in interface_handlers.c, which was renamed from
interface_ops.c, to convert operators to the UI handler. UI code notes:
* uiBeginBlock/uiEndBlock/uiFreeBlocks now takes a context argument, this is
  required to properly cancel things like timers or tooltips when the region
  gets removed.
* UI_add_region_handlers will add the region level UI handlers, to be used
  when adding keymap handlers etc. This replaces the UI keymap.
* When the UI code starts a modal interaction (number sliding, text editing,
  opening a menu, ..), it will add an UI handler at the window level which
  will block events.
Windowmanager changes:
* Added an UI handler next to the existing keymap and operator modal handlers.
  It has an event handling and remove callback, and like operator modal handlers
  will remember the area and region if it is registered at the window level.
* Removed the MESSAGE event.
* Operator cancel and UI handler remove callbacks now get the
  window/area/region restored in the context, like the operator modal and UI
  handler event callbacks.
* Regions now receive MOUSEMOVE events for the mouse going outside of the
  region. This was already happening for areas, but UI buttons are at the region
  level so we need it there.
Issues:
* Tooltips and menus stay open when switching to another window, and button
  highlight doesn't work without moving the mouse first when Blender starts up.
  I tried using some events like Q_FIRSTTIME, WINTHAW, but those don't seem to
  arrive..
* Timeline header buttons seem to be moving one pixel or so sometimes when
  interacting with them.
* Seems not due to this commit, but UI and keymap handlers are leaking. It
  seems that handlers are being added to regions in all screens, also in regions
  of areas that are not visible, but these handlers are not removed. Probably
  there should only be handlers in visible regions?

Port of part of the Interface code to 2.50.
This is based on the current trunk version, so these files should not need
merges. There's two things (clipboard and intptr_t) that are missing in 2.50
and commented out with XXX 2.48, these can be enabled again once trunk is
merged into this branch.
Further this is not all interface code, there are many parts commented out:
* interface.c: nearly all button types, missing: links, chartab, keyevent.
* interface_draw.c: almost all code, with some small exceptions.
* interface_ops.c: this replaces ui_do_but and uiDoBlocks with two operators,
  making it non-blocking. 
* interface_regions: this is a part of interface.c, split off, contains code to
  create regions for tooltips, menus, pupmenu (that one is crashing currently),
  color chooser, basically regions with buttons which is fairly independent of
  core interface code.
* interface_panel.c and interface_icons.c: not ported over, so no panels and
  icons yet. Panels should probably become (free floating) regions? 
* text.c: (formerly language.c) for drawing text and translation. this works
  but is using bad globals still and could be cleaned up.
Header Files:
* ED_datafiles.h now has declarations for datatoc_ files, so those extern
  declarations can be #included instead of repeated.
* The user interface code is in UI_interface.h and other UI_* files.
Core:
* The API for creating blocks, buttons, etc is nearly the same still. Blocks
  are now created per region instead of per area.
* The code was made non-blocking, which means that any changes and redraws
  should be possible while editing a button. That means though that we need
  some sort of persistence even though the blender model is to recreate buttons
  for each redraw. So when a new block is created, some matching happens to
  find out which buttons correspond to buttons in the previously created block,
  and for activated buttons some data is then copied over to the new button.
* Added UI_init/UI_init_userdef/UI_exit functions that should initialize code
  in this module, instead of multiple function calls in the windowmanager.
* Removed most static/globals from interface.c.
* Removed UIafterfunc_ I don't think it's needed anymore, and not sure how it
  would integrate here?
* Currently only full window redraws are used, this should become per region
  and maybe per button later.
Operators:
* Events are currently handled through two operators: button activate and menu
  handle. Operators may not be the best way to implement this, since there are
  currently some issues with events being missed, but they can become a special
  handler type instead, this should not be a big change.
* The button activate operator runs as long as a button is active, and will
  handle all interaction with that button until the button is not activated
  anymore. This means clicking, text editing, number dragging, opening menu
  blocks, etc.
* Since this operator has to be non-blocking, the ui_do_but code needed to made
  non-blocking. That means variables that were previously on the stack, now
  need to be stored away in a struct such that they can be accessed again when
  the operator receives more events.
* Additionally the place in the ui_do_but code indicated the state, now that
  needs to be set explicit in order to handle the right events in the right
  state. So an activated button can be in one of these states: init, highlight,
  wait_flash, wait_release, wait_key_event, num_editing, text_editing,
  text_selecting, block_open, exit.
* For each button type an ui_apply_but_* function has also been separated out
  from ui_do_but. This makes it possible to continuously apply the button as
  text is being typed for example, and there is an option in the code to enable
  this. Since the code non-blocking and can deal with the button being deleted
  even, it should be safe to do this.
* When editing text, dragging numbers, etc, the actual data (but->poin) is not
  being edited, since that would mean data is being edited without correct
  updates happening, while some other part of blender may be accessing that
  data in the meantime. So data values, strings, vectors are written to a
  temporary location and only flush in the apply function.
Regions:
* Menus, color chooser, tooltips etc all create screen level regions. Such menu
  blocks give a handle to the button that creates it, which will contain the
  results of the menu block once a MESSAGE event is received from that menu
  block.
* For this type of menu block the coordinates used to be in window space. They
  are still created that way and ui_positionblock still works with window
  coordinates, but after that the block and buttons are brought back to region
  coordinates since these are now contained in a region.
* The flush/overdraw frontbuffer drawing code was removed, the windowmanager
  should have enough information with these screen level regions to have full
  control over what gets drawn when and to then do correct compositing.
Testing:
* The header in the time space currently has some buttons to test the UI code.
