Pretty much straightforward change, made in the same way as
texture input node.
Shall not be any regressions or crashes when mixing usage
of 2.66 and current trunk.
It works in a newest gcc (e.g. 4.6.3) but fails here:
i686-apple-darwin11-llvm-gcc-4.2 (GCC) 4.2.1 (Based on Apple Inc. build
5658) (LLVM build 2336.11.00)
The old 2.5 code was just drawing a blended rect over buttons, which looks bad
in cases the backdrop is undefined.
Now widget drawing code just draws everything half transparent. Much nicer!
Time for textured backdrops? ;)
* Add, Move and Remove Socket operators missed a notifier for UI redraw.
Note: ND_DISPLAY seems to be for the Text editor only, according to WM_types.h, but seems to be used in quite a few places.
Time to cleanup notifiers again.
PyNodes opens up the node system in Blender to scripters and adds a number of UI-level improvements.
=== Dynamic node type registration ===
Node types can now be added at runtime, using the RNA registration mechanism from python. This enables addons such as render engines to create a complete user interface with nodes.
Examples of how such nodes can be defined can be found in my personal wiki docs atm [1] and as a script template in release/scripts/templates_py/custom_nodes.py [2].
=== Node group improvements ===
Each node editor now has a tree history of edited node groups, which allows opening and editing nested node groups. The node editor also supports pinning now, so that different spaces can be used to edit different node groups simultaneously. For more ramblings and rationale see (really old) blog post on code.blender.org [3].
The interface of node groups has been overhauled. Sockets of a node group are no longer displayed in columns on either side, but instead special input/output nodes are used to mirror group sockets inside a node tree. This solves the problem of long node lines in groups and allows more adaptable node layout. Internal sockets can be exposed from a group by either connecting to the extension sockets in input/output nodes (shown as empty circle) or by adding sockets from the node property bar in the "Interface" panel. Further details such as the socket name can also be changed there.

Curves widget error: after deleting a point, and click to add a new point, on dragging
it the point flipped up 20 pixels. Was caused by changed layout and region view matrix.
Solved by storing actual mousecoords instead of mapped ones.
To make circle select allow pass-through for view events, several issues have to be
tackled.
1) other modal ops run on top (border select),
2) middlemouse is used now
3) and what for tablet/trackpad or people without middlemouse?
The MMB deselection for border/circle is not optimal now... needs rethinking this.
Better would be to check on non-persistant-modality for circle, to start with gesture style
event like lasso or border can do now.
This makes it so sample line (for all image editor, sequencer and compositor)
displaying managed color for byte buffers as well. It was simply not implemented
before.
alpha, added option when drawing depth to disable alpha clip override.
We use that in texture paint cursor now. Not too common but may be
useful for people dealing with cloning plugins.
Reported by kgeogeo on irc, thanks.
paint. Was own regression when optimizing colour operations. I will not
use an alpha bit mask since it may run into portability issues with byte
order.
Zooming in on images in Image window now shows pixels again (was filtered).
Now the glaDrawPixelsTex() and glaDrawPixelsAuto() have an argument to
define if images should zoom in with linear filter, or draw pixels.
Image Editor and 3D view background image now use new automatic switching for
drawing GPU texture or OpenGL DrawPixels too. For large zoomed images
it gives massive speedup.
Automatic switching for drawing pixel buffers via glDrawPixels or using GPU textures
It works with a User Preference limit, in megapixels, to define whether to use
GPU or direct pixel drawing. Default is now initialized to 10 MP (4k buffers).
Especially for zooming out (draw smaller) texture drawing is much smaller. Also
Nvidia cards typically draw much faster with textures in general.
Added to node backdrop first now, the other editors follow in a next commit.
For coders: added new DNA function to initialize new struct variables, so you
don't have to sub-version files anymore.
DNA_struct_elem_find(fd->filesdna, "structname", "typename", "varname")
"filesdna" is the sdna description of the current file being versioned.
too nice but it frees the Ctrl-LClick shortcut and allows us to set
invert mode for other paint tools, such as sharpen vs blur or invert
colour for draw brush. This conflict has existed on GSOC branch, better
resolve now before merging invert functionality.
- without python builds without warnings.
- replace MAXFLOAT -> FLT_MAX in some areas, MAXFLOAT overflows (lager then float range).
- add cmake option WITH_GCC_MUDFLAP to enable libmudflap use.
