Various changes made in the process of working on the UI code:
* Added functions to generate Timer events. There was some unfinished code to
create one timer per window, this replaces that with a way to let operators
or other handlers add/remove their own timers as needed. This is currently
delivered as an event with the timer handle, perhaps this should be a notifier
instead? Also includes some fixes in ghost for timer events that were not
delivered in time, due to passing negative timeout.
* Added a Message event, which is a generic event that can be added by any
operator. This is used in the UI code to communicate the results of opened
blocks. Again, this may be better as a notifier.
* These two events should not be blocked as they are intended for a specific
operator or handler, so there were exceptions added for this, which is one
of the reasons they might work better as notifiers, but currently these
things can't listen to notifier yet.
* Added an option to events to indicate if the customdata should be freed or
not.
* Added a free() callback for area regions, and added a free function for
area regions in blenkernel since it was already there for screens and areas.
* Added ED_screen/area/region_exit functions to clean up things like operators
and handlers when they are closed.
* Added screen level regions, these will draw over areas boundaries, with the
last created region on top. These are useful for tooltips, menus, etc, and
are not saved to file. It's using the same ARegion struct as areas to avoid
code duplication, but perhaps that should be renamed then. Note that redraws
currently go correct, because only full window redraws are used, for partial
redraws without any frontbuffer drawing, the window manager needs to get
support for compositing subwindows.
* Minor changes in the subwindow code to retrieve the matrix, and moved
setlinestyle to glutil.c.
* Reversed argument order in WM_event_add/remove_keymap_handler to be consistent
with modal_handler.
* Operators can now block events but not necessarily cancel/finish.
* Modal operators are now stored in a list in the window/area/region they were
created in. This means for example that when a transform operator is invoked
from a region but registers a handler at the window level (since mouse motion
across areas should work), it will still get removed when the region is closed
while the operator is running.

2.5 getting-back-into-coding commit :)
- cleaned up join and split operations. Most noticable is operator callback
design, which should make a design based on user-less exec() first, then
wrap invoke() and modal() around it. The exec() should be callable with
only Context and properties.
- split now works again; and inversed as previously, if you drag from a
triangle (action zone) inside area it subdivides area as expected.
- dragging from triangle outside area, over an edge, joins areas
- split has been simplified, it had too many options... it could just work
simpler (now)
- 'action zone' now is an operator itself, a widget sending an ACTIONZONE event,
which can be handled by others (so other gestures can be added in action zone
too)
Still evaluating:
- context gets set where?
- code structure confuses... what are proper functions for operators?
- what is WM... should low level screen stuff more there?
- when do you send event, notifier?
- files grow to large, will clean
Oh yeah and docs, docs, docs. Coming! :)

2.5 Branch
==========
* Changed wmOperatorType, removing init/exit callbacks and adding cancel
callback, removed default storage in favor of properties. Defined return
values for exec/invoke/modal/cancel.
* Don't allocate operator on the stack, and removed operator copy for
handlers. Now it frees based on return values from callbacks, and just
keeps a wmOperator on the heap. Also it now registers after the operator
is fully finished, to get the correct final properties.
* Changed OP_get_* functions to return 1 if the property is found and 0
otherwise, gives more readable code in my opinion. Added OP_verify_*
functions to quickly check if the property is available and set if it's
not, that's common for exec/invoke.
* Removed WM_operatortypelist_append in favor of WM_operatortype_append
which takes a function pointer instead of a list, avoids macro's and
duplicating code.
* Fix a crash where the handler would still be used while it was freed by
the operator.
* Spacetypes now have operatortypes() and keymap() callbacks to abstract
them a bit more.
* Renamed C->curarea to C->area for consistency. Removed View3D/View2D/
SpaceIpo from bContext, seems bad to keep these.
* Set context variables like window/screen/area/region to NULL again when
leaving that context, instead of leaving the pointers there.
* Added if(G.f & G_DEBUG) for many of the prints, makes output a bit
cleaner and easier to debug.
* Fixed priority of the editors/interface module in scons, would otherwise
give link errors.
* Added start of generic view2d api.
* Added space_time with some basic drawing and a single operator to change
the frame.

2.5 Branch
==========
* Changed wmOperatorType, removing init/exit callbacks and adding cancel
callback, removed default storage in favor of properties. Defined return
values for exec/invoke/modal/cancel.
* Don't allocate operator on the stack, and removed operator copy for
handlers. Now it frees based on return values from callbacks, and just
keeps a wmOperator on the heap. Also it now registers after the operator
is fully finished, to get the correct final properties.
* Changed OP_get_* functions to return 1 if the property is found and 0
otherwise, gives more readable code in my opinion. Added OP_verify_*
functions to quickly check if the property is available and set if it's
not, that's common for exec/invoke.
* Removed WM_operatortypelist_append in favor of WM_operatortype_append
which takes a function pointer instead of a list, avoids macro's and
duplicating code.
* Fix a crash where the handler would still be used while it was freed by
the operator.
* Spacetypes now have operatortypes() and keymap() callbacks to abstract
them a bit more.
* Renamed C->curarea to C->area for consistency. Removed View3D/View2D/
SpaceIpo from bContext, seems bad to keep these.
* Set context variables like window/screen/area/region to NULL again when
leaving that context, instead of leaving the pointers there.
* Added if(G.f & G_DEBUG) for many of the prints, makes output a bit
cleaner and easier to debug.
* Fixed priority of the editors/interface module in scons, would otherwise
give link errors.
* Added start of generic view2d api.
* Added space_time with some basic drawing and a single operator to change
the frame.
