The face sets color copy to the GPU was done outside of the loop,
probably after a merge error in a rebase.
Also, the default color was initialized using the wrong type.

Sculpt Vertex Colors is a painting system that runs inside sculpt mode, reusing all its tools and optimizations. This provides much better performance, easier to maintain code and more advanced features (new brush engine, filters, symmetry options, masks and face sets compatibility...). This is also the initial step for future features like vertex painting in Multires and brushes that can sculpt and paint at the same time.
This commit includes:
- SCULPT_UNDO_COLOR for undo support in sculpt mode
- SCULPT_UPDATE_COLOR and PBVH flags and rendering
- Sculpt Color API functions
- Sculpt capability for sculpt tools (only enabled in the Paint Brush for now)
- Rendering support in workbench (default to Sculpt Vertex Colors except in Vertex Paint)
- Conversion operator between MPropCol (Sculpt Vertex Colors) and MLoopCol (Vertex Paint)
- Remesher reprojection in the Voxel Remehser
- Paint Brush and Smear Brush with color smoothing in alt-smooth mode
- Parameters for the new brush engine (density, opacity, flow, wet paint mixing, tip scale) implemented in Sculpt Vertex Colors
- Color Filter
- Color picker (uses S shortcut, replaces smooth)
- Color selector in the top bar

This means all the antiailasing is done inside the fragment shader.
We use a Signed Distance Field to draw the 2D rounded boxes. This ensure
the best quality for AA.
This reduce the averge Batch for widget to 16 verts instead of ~600 and
reduce overshading a lot.
Theme Emboss alpha and tria alpha needs to be changed after this refactor.
The shadow drawing is left unchanged and still use geometry.

This adds object motion blur vectors for EEVEE as well as better noise
reduction for it.
For TAA reprojection we just compute the motion vector on the fly based on
camera motion and depth buffer. This makes possible to store another motion
vector only for the blurring which is not useful for TAA history fetching.
Motion Data is saved per object & per geometry if using deformation blur.
We support deformation motion blur by saving previous VBO and modifying the
actual GPUBatch for the geometry to include theses VBOs.
We store Previous and Next frame motion in the same motion vector buffer
(RG for prev and BA for next). This makes non linear motion blur (like
rotating objects) less prone to outward/inward blur.
We also improve the motion blur post process to expand outside the objects
border. We use a tile base approach and the max size of the blur is set via
a new render setting.
We use a background reconstruction method that needs another setting
(Background Separation).
Sampling is done using a fixed 8 dithered samples per direction. The final
render samples will clear the noise like other stochastic effects.
One caveat is that hair particles are not yet supported. Support will
come in another patch.

Limit support for `GLEW_ARB_base_instance` to OpenGL 4.0 and higher. NVIDIA Quadro FX 4800
(TeraScale) report that they support GLEW_ARB_base_instance, but the driver does not support
`GLEW_ARB_draw_indirect` as it has an OpenGL3 context what also matches the minimum needed
requirements.
We use `GLEW_ARB_draw_indirect` as a target for `glMapBuffer(Range)` what is part of the
OpenGL 4 API. So better disable it when we don't have an OpenGL4 context.
Note: fix should be ported to Blender 2.83 LTS

The was caused by 8b347fc2cd as the old BONESEL_NOSEL flag
handled the -1 case (used for none).
Instead of checking for -1, remove these elements from the array
as selection code makes decisions based on the number of hits detected.
This reduce the base size of the shaderinterface from 400 to 136 bytes.
Improves memory usage and cache coherency when querying a lot of uniforms
at once.
This use the latest GPUTexture change to use the sampler state to avoid
the pole issues instead of using GLSL hacks.
This should fix T73942: Eevee mipmaps not respecting border mode.
Note that this also fix some discrepencies between cycles and eevee (like
boxmapping + clip).
This bridge between the new sampler state support from GPUTexture and
draw material handling.
The Sampler State is just the one from the texture for now. No change in
logic.
This cleanup use the recent changes in shader interface to allow querying
the binding location a texture should use.
This should aleviate all issue we have with texture state change recompiling
the shaders at drawtime.
All binds are now treated like persistent binds and will stick until a new
shading group bind a different shader. The only difference is that you can
still change it with a new subgroup or same shader shgroup.
Since unbinding can be heavy we only do it when using `--debug-gpu`.
These are the modifications:
-With DRW modification we reduce the number of passes we need to populate.
-Rename passes for consistent naming.
-Reduce complexity in code compilation
-Cleanup how renderpass accumulation passes are setup, using pass instances.
-Make sculpt mode compatible with shadows
-Make hair passes compatible with SSS
-Error shader and lookdev materials now use standalone materials.
-Support default shader (world and material) using a default nodetree internally.
-Change BLEND_CLIP to be emulated by gpu nodetree. Making less shader variations.
-Use BLI_memblock for cache memory allocation.
-Renderpasses are handled by switching a UBO ref bind.
One major hack in this patch is the use of modified pointer as ghash keys.
This rely on the assumption that the keys will never overlap because the
number of options per key will never be bigger than the pointed struct.
The use of one single nodetree to support default material is also a bit hacky
since it won't support concurent usage of this nodetree.
(see EEVEE_shader_default_surface_nodetree)
Another change is that objects with shader errors now appear solid magenta instead
of shaded magenta. This is only because of code reuse purpose but could be changed
if really needed.

This remove the complexity of queriying the locations at runtime and
allows for more performance and upfront binding specifications.
The benefit of doing everything at creation time is that we can assign binding
points in a predictable order which is going to be somewhat the same for
every similar shader.
This also rewrite GPU_vertformat_from_shader to not use shaderface.
This is to keep the shaderface simple. If it becomes necessary to not query
the shader after creation (i.e: vulkan?) we could just create the vert
format in advance at compilation for PyGPU shaders.
