I doubt we can do much better. Most of the aliasing comes from the edge
detection which does not use a lot of samples. We could use more samples
but then the detection becomes way more complex and expensive.
The second issue comes from the reconstruction (AA pass) that only bleed
adjacent pixels in if their line direction is perpendicular to the offset.
This makes corner gaps on certain diagonals.
We can't use the fast path when the mesh is used by mulitple objects and so
slower sculpting is expected then. But fake users should not affect this. This
also fixes the same type of error in a few other areas.
Blender supports locking vertex groups to prevent changes to the
weights. However, as mentioned in comments for D3837, it is hard
to use this because there is no interface for locking in 3D View.
This adds a red shade to bones that are associated with a locked
weight group during weight paint mode, as the first step to adding
such interface. The next step is adding a pie menu for lock/unlock.

This way we remove the need for the srgb boolean uniform and a lot of code complexity. However, mesh update is going to be a bit slower.
I did not benchmark the performance impact.
This also fix a typo in draw_cache_impl_particles.c and fix hair not using vertex color in workbench.

EEVEE Soft shadows were not rendered correctly during viewport
rendering. The reason for this is that during viewport rendering the
shadow buffers were only update once and not per sample. This resulted
that all the samples calculated the same shadow.
This fix moves the call to `EEVEE_shadows_update` from cache finished to
draw scene. This needs to happen before `EEVEE_lightprobes_refresh`.

Based on @fclem's suggestion in D6421, this commit implements support for
storing all tiles of a UDIM texture in a single 2D array texture on the GPU.
Previously, Eevee was binding one OpenGL texture per tile, quickly running
into hardware limits with nontrivial UDIM texture sets.
Workbench meanwhile had no UDIM support at all, as reusing the per-tile
approach would require splitting the mesh by tile as well as texture.
With this commit, both Workbench as well as Eevee now support huge numbers
of tiles, with the eventual limits being GPU memory and ultimately
GL_MAX_ARRAY_TEXTURE_LAYERS, which tends to be in the 1000s on modern GPUs.
Initially my plan was to have one array texture per unique size, but managing
the different textures and keeping everything consistent ended up being way
too complex.
Therefore, we now use a simpler version that allocates a texture that
is large enough to fit the largest tile and then packs all tiles into as many
layers as necessary.
As a result, each UDIM texture only binds two textures (one for the actual
images, one for metadata) regardless of how many tiles are used.
Note that this rolls back per-tile GPUTextures, meaning that we again have
per-Image GPUTextures like we did before the original UDIM commit,
but now with four instead of two types.

When sculpting and doing a image render the workbench used the sculpt
batch what is created by a different GPU context and would not show up.
In debug builds an assert for this case is checked. I rechecked all
`use_sculpt_pbvh` that it also checked if it was rendering. Only the
workbench deferred didn't do this for the default render mode.
With this change the user can render a workbench render directly from
sculpt mode.
When in sculptmode the wireframe coloring should always be disabled.
When an object was sculpted but had modifiers this was not detected and
the colors were still shown.
This fix will disable wireframe coloring for any object that is in
sculptmode.
Vertex colors behaved differently as the paint overlay mixed the colors
in display mode and the results was multiplied on top of the original
shading.
This patch will align the implementation to texture painting where the
colors are drawn by the workbench engine so the correct shading is
applied.
This also means that we don't show the vertex colors overlay when not
in solid mode.

Due to recent refactoring of the overlay unification the camera limits
were also visible when the overlays were turned off. This was because
the `draw_extra` had an exception for when looking through the camera.
This change also takes the global hide overlays into account. So now the
camera limits will not be drawn when overlays are turned off. This also
fixed other camera related overlay drawing.

Viewport: Disable Clipping For EEVEE and External Renderers
Currently it is possible that, when using viewport clipping, the display and tools communicate
different information to the user then the renderer does. The reason is
that the renderer does not support viewport clipping. Both EEVEE and
Cycles do not support it.
This patch will disable the clipping in all the tools and drawing code
when the viewport drawing mode is `Material Preview` or `Rendered`.
This patch introduces a `RV3D_CLIPPING_ENABLED` util that checks if
clipping is enabled for the given `rv3d` and `v3d`. Also in places where
it was needed we added the `ViewContext` as a carrier for the `View3D`
and `RegionView3D`.
There are a few areas in the tooling (select, projection painting) that
still needs to be tackled after this patch.

This seems to only affect some drivers. Rendering to multiple targets

The edit overlays were drawn dispite of the global hide overlays toggle.
This patch checks the global hide overlay toggle to see if it needs to draw
