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 removes some fragment shader hacks and improve the support of
different repeat & filtering modes.
This fix T77453 Image texture not repeating in viewport
This makes it easier to track as well as allowing us to sample the same
texture with different sampling parameters (which should fix the related
T73942 in the long run).

All textures in workbench are using linear interpolation. The fragment
shader modifies the uv coordinates to sample always in the center of a
texel. In rare conditions the GPU could sample an incorrect value due to
rounding errors making some rendering artifacts.
This patch skips the interpolation in the fragment shader to remove
these render artifacts.

When setting the Viewport Anti-Aliasing samples in the user preferences
to a lower sample count the anti-aliasing was not reset. This lead to
incorrect result as the accum buffer would still hold the values of the
larger sample count.
This fix resets the TAA when the sample count is changed.

When sculpting the GPU batches are constructed with only the required data
for a single viewport. When that viewport changes shading or coloring mode (object
to vertex) batches might not hold all the needed information.
There is also a case when you have two 3d viewport one in object color
mode and the other in vertex color mode that the GPU batches were
updated without any vertex colors.
In order to fix these category of issues this patch would always
construct the full GPU batches for sculpting.

In the situation that the viewport was set to solid/texture mode and
switch to wireframe and sculpt mode, an assert was triggered in
`workbench_cache_sculpt_populate`.
The problem comes from the fact by no data being modified when switching
viewlayers.
To follow what the external render engines do, we completely reset the
viewport by freeing the GPUViewport to avoid any cached data from being
kept.
This fix case where you have wireframe on top of infront objects but
workbench AA conflicts and they appear to not be occluded.
Also T74923 is still fixed but we extend the fix to not mess the case when
using a mode that does not support infront.
The material indices in a mesh can exceed the number of available materials
slots in the object or mesh, sculpt drawing was not taking that into account.
When setting the number of cavity samples to a high number blender could
write out of bounds.
This patch will harmonize the number of iterations in the same way how
it is done during execution.

EEVEE and Workbench both had the same issue that they continue with the
last sample when leaving navigating. This is ok for regular meshes as
they are all the same. For multiresolution it ain't as a low res version
of the mesh is used during navigation.
This patch also resets the AA samples when the user leaves navigation.
Problem is that the RenderEngines will change the RenderData cfra when
rendering (when time remapping is used -- at least workbench/eevee/
gpencil do a combination of BKE_scene_frame_get() plus
RE_GetCameraWindow() which alters the RenderData cfra).
Later on in the pipeline, the Compositor will use this RenderData cfra
to determine the output file name for the FileOutput node. (In contrast
to this, the 'regular' Output will use the Scene's RenderData -- not the
Render's -- cfra [which hasnt been altered])
It is not entirely clear why RE_GetCameraWindow was setting the cfra on
the Render, but it appears to be legacy OGL rendering related and is not
needed anymore.
Removing this will keep the cfra as needed for the Compositor FileOutput
node.
This issue became visible after fixing other TAA issues recently.
The sample count of the first frame wasn't reset resulting that the
incorrect resolve took place. This issue was already there beforehand,
it is just much clearer during the recent changes.
Now the `taa_sample will be reset when performing an animation playback
in the 3d viewport.
When the TAA is finished the screen can still be redrawn by other
operations without the TAA resets.
If that happened the TAA did add a blank sample to the result as the
scene wasn't drawn, but the was processed.

This patch will add an early exit in the case TAA was finished. Note
that there are still some cases still not working. The overlay engine
can in certain circumstances draw directly into the default_fb what can
lead to render artifacts.
For In Front Objects we need to use the in front depth buffer.
This patch will use the in front depth buffer and also makes sure that
it is filled with the center pixel depth.
