Currently this stuff is used for 2d tracking job only, but the same
thing would necessary for camera solver job, so moved it into more
general utility stuff.
The problem was in fact in the changes made to blend_ramp() func at rev42164. The checks on green pointer (if(g) {...) were checking the existance of a valid value (i.e. if input color was rgb or only shades of grey in r pointer), but as we get now a full float[3] pointer, this test is no more possible. And doing if(r_col[1]) {... was wrong, as it only broke things in case green was 0.0 (which was the case with the generated glare color of bug report).
So, just removed all those tests!
This change adds RNA access to tesselated face UVs and colors (MTFACE and MCOL), primarily for use by plugin renderers (e.g. cycles). The RNA mesh properties to get to these are prefixed with "tessface_" and additionally the help text states that these are for renderers, to try not to confuse existing mesh editing tool scripts into thinking they could just start using these values.
Transparent rendering can't be implemented in way it gives accurate shading in
3d viewport. It's acceptable for object mode, but when you're in edit mode
it gives more problems than benefits of seeing transparent faces.
This is possible fix for for weird polygons in [#29255] Object invisible and weird polygons appearance
I've written a convenient function that returns the sibling of a node in the
red-black tree implementation originally implemented by Joshua Leung.
I want to use this get_sibling() function in the future to implement the missing
removal function of the red-black tree implementation.
For now the get_sibling() function just simplifies the get_uncle() function.
Just like the rest of the red-black tree implementation this diff is based on

This issue it totally related on issue with changing object datablock.
For curves it used to guess object type from curve datablock based on
count of control points in V direction.
This quess fails in case when SurfCircle datablock is trying to be reused
by another surface object or as another sample empty surface databouck used
to be treated as curve.
Store type in Curve when creating new Curve datablock which is used in
this object type quessing function.
Note: Previously saved files wouldn't change behavior at all.
If enter is pressed outside of any button in menu, generate two menu return values:
- UI_RETURN_CANCEL so button wouldn't be executed
- UI_RETURN_POPUP_OK so callback associated with popup block would be executed
There were some issues with PBVH which prevented working it for meshes without faces.
Discussed with Brecht, for benefits of dynamic-topology-sculpting and so better to
make PBVH survive such things.
Added some extra NULL-pointer checks for this.
- setting the color channels on save as would ignore the channel - BW/RGB/RGBA setting.
now its used when available but still need to hide BW for formats blender can only write as color.
move these checks from creator into BKE's image.c, this way we dont need the defines for creator, scons was missing DDS, HDR & Cineon for example and nobody noticed.
