Many high-level functions with unrelated code were templated based on
the color attribute domain and type. In the end, those were just a few
branches though, similar to other branches. So to reduce binary bloat
and clarify code, move tempates to the point where separate types are
actually needed. Also move constant code out of loops, and use generic
arrays and spans to store some caches. The binary ended up 53 KB
smaller for me, which isn't much but it's in the right direction.
Performance wise nothing really changes. The vast majority of time in
vertex paint is spent on unrelated things like calculating normals or
uploading GPU buffers anyway.
The one ugly part I didn't account for when I started is the casting
between the "ColorGeometry" and "ColorPaint" types. I'm not sure that
this is correct, but it's just a more explicit version of what was
there already.
Pull Request: https://projects.blender.org/blender/blender/pulls/109941
A lot of files were missing copyright field in the header and
the Blender Foundation contributed to them in a sense of bug
fixing and general maintenance.
This change makes it explicit that those files are at least
partially copyrighted by the Blender Foundation.
Note that this does not make it so the Blender Foundation is
the only holder of the copyright in those files, and developers
who do not have a signed contract with the foundation still
hold the copyright as well.
Another aspect of this change is using SPDX format for the
header. We already used it for the license specification,
and now we state it for the copyright as well, following the
FAQ:

BlendType max incorrectly returns the minimum in BLI_color_mix.hh
This differential fixes it to return the maximum.
Maniphest Tasks: T102216
Ref D16364
- Add missing doxy-section for Apply Parent Inverse Operator
- Use identity for None comparison in Python.
- Remove newline from operator doc-strings.
- Use '*' prefix multi-line C comment blocks.
- Separate filenames from doc-strings.
- Remove break after return.
- Verrtex paint mode has been refactored into C++ templates.
It now works with both byte and float colors and point
& corner attribute domains.
- There is a new API for mixing colors (also based
on C++ templates). Unlike the existing APIs byte
and float colors are interpolated identically.
Interpolation does happen in a squared rgb space,
this may be changed in the future.
- Vertex paint now uses the sculpt undo system.
