in the UI
This is the second part of the fixes for [#32492], making it easier to identify
which part of a driver (i.e. which of its targets) is causing problems
A number of additional/related changes needed to be made:
* Red-alert status for layouts is now propagated down to child layouts when they
are created. This is needed as otherwise some of the templates used in the Graph
Editor driver settings won't actually get the red-alert status flushed down to
them. Also, note that this status needs to be set before any widgets are added
to the layout, or else the settings aren't applied when the relevant widgets get
created.
* "Single Property" RNA-Paths resulting in out of bounds array access will now
trigger an error status and appropriate warnings
TODO:
* The error tagging doesn't get applied immediately after variables are created,
or their types changed
* There was also some other weirdness involved when a higher-value flag (1<<10)
was used for this setting, which needs further attention
Blender's data link button (typically with menu and searching options)
now has a X icon to clear its contents.
Before you had to click, delete text, enter.
For example:
- Object Parent
- Modifier objects or vertexgroups
This fix saves each user 100 clicks per day, with 100k users
that's 3 billion clicks per year!
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.
Also fixed CTX_FOO_ macros when building without i18n, those were kinda wrong.
And hid i18n ui section in userpreferences when built without its support too.
Nice formatted version (pictures soon):

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)
If this is needed we can add the reset button back as an option for certain operators,
but AFAICS any operator with enough settings that resetting them all would be annoying - could have presets enabled.
When adding extra context data in a layout using uiLayoutSetContextPointer, this info was not inherited by popup menus generated in this layout. While operators from regular buttons work fine, the data is missing in operators from menus and such. This patch copies the bContextStore from buttons to the new uiLayout used for popups.
