Caused by rBf75449b5f2b04b79, which was missing a null check when
attempting to extract a `CustomData` pointer from an mesh that might
be null if the object isn't a mesh object. The commit added null checks
elsewhere, so simply adding them here is a straightforward fix.

- Compute ref let the size of dispatch be modified just before drawing.
- Barrier call makes it possible to chain multiple compute passes in one pass.
- DRW_shgroup_vertex_buffer_ref is the analog of DRW_shgroup_uniform_block_ref.
This commit adds infrastructure for 8 bit signed integer attributes.
This can be useful given the discussion in T94193, where we want to
store spline type, Bezier handle type, and other small enums as
attributes.
This is only exposed in the interface in the attribute lists, so it
shouldn't be an option in geometry nodes, at least for now.
I expect that this type won't be used directly very often, it
should mostly be cast to an enum type. However, with support
for 8 bit integers, it also makes sense to add things like mixing
implementations for consistency.

The check for existence of custom data layers did not take wrapper nature of
mesh into account.
Quickest and safest for 3.1 solution is to take care of branching of checks
in the draw manager.
Ideally both wrapper and mesh access will happen via the same public API
without branching in the "user" code. That is something outside of the fix
for the coming release though.

Byte images are converted to float. Due to an issue how VSE cache is
freeing its images we cannot store these float buffers what leads
to recalculating it for each change in the image editor.
This fix will reduce the slowdown to areas that have the root cause of
the memory leak, so the buffers can be reused between refreshes.
NOTE: The root cause should still be fixed.
Thanks for reporting Sybren!
When viewing backdrop on top of the node grid, the grid would be
rendered black when the mode wasn't set to RGBA. This fix fixes this by
reverting the previous fix of drawing the backdrop and implement a
different one that recomputes the UV coordinates on the screen edges.
Part of T91671.
Not much else to say, this is mainly a massive deletion of code.
Note that a few cleanups possible after this proxy removal were kept out
of this commit to try to reduce a bit its size.

This patch refactors the "Hair" data-block, which will soon be renamed
to "Curves". The larger change is switching from an array of `HairCurve`
to find indices in the points array to simply storing an array of offsets.
Using a single integer instead of two halves the amount of memory for that
particular array.
Besides that, there are some other changes in this patch:
- Split the data-structure to a separate `CurveGeometry`
DNA struct so it is usable for grease pencil too.
- Update naming to be more aligned with newer code and the style guide.
- Add direct access to some arrays in RNA
-- Radius is now retrieved as a regular attribute in Cycles.
-- `HairPoint` has been renamed to `CurvePoint`
-- `HairCurve` has been renamed to `CurveSlice`
- Add comments to the struct in DNA.
The next steps are renaming `Hair` -> `Curves`, and adding support
for other curve types: Bezier, Poly, and NURBS.

This is a temp fix for a memory leak where the VSE isn't aware that a
float representation of the image could exist. The VSE somehow doens't
clears it (refcounter is still 1).
The work around is just to let the image engine clean up all the data it
created. Potential this would add more overhead when buffers are needed
more than once.
Using opt-in instead of opt-out to make code easier to read.
Add combined flag enum.
Making restrict an inverse flag option because it is so rare to
use it.
Since splitting the depth and the color shader in the image engine the
backdrop wasn't visible anymore. The reson is that the min max uv
coordinates were never working for the node editor backdrop that uses
its own coordinate space.
This partial fix will ignore the depth test when drawing the color part
of the backdrop. This will still have artifacts that are visible when
showing other options as RGBA.
Proper fix would be to calculate the the uv vbo in uv space and not in
image space.
Can also happen in other places when the overlay engine is active. Some
parts of the overlay engine uses builtin shaders, but disable the color
space conversion to the target texture.
Currently there the overlay engine has its own set of libraries it could
include and defined a macro to pass-throught the color space conversion.
The library include mechanism currently fails when it couldn't find the
builtin library in the libraries of the overlay engine. This only
happened in debug mode.
This change will not fail, but warns the developer if a library could
not be included. In the future this should be replaced by a different
mechanism that can disable the builtin library. See {T95382}.
Empty (UDIM) tiles where drawn with a transparency checkerboard. They
should be rendered with a border background. The cause is that the image
engine would select a single area that contained all tiles and draw them
as being part of an image.
The fix is to separate the color and depth part of the image engine
shader and only draw the depths of tiles that are enabled.
Parameter was used to still be compatible with the previous drawing mode.
The previous mode isn't available anymore so the parameter can should be
removed.
After showing the alpha in the image editor the setting was not reset
so all images in the editor showed as being transparent.
This commit fixes this by resetting the flag before updating.
