Some GPU's have support for compute shaders, but don't support
GLSL 4.3. This resulted in compiler errors and crashes.
This issue could have been solved by supporting older GLSL languages but
that would have been a hassle to get it right. We already have a
fallback in place for GPU's that don't support compute shaders at all.
* Added a limited "fast draw" mode to pbvh drawing
that tries to limit data sent to the GPU.
- Facesets and mask data are disabled.
- Indexed mode is forced.
- Does not work (at all) for multires.
* Finally fixed some outstanding bmesh sculpt undo bugs:
- Forgot to mark pbvh nodes to update their bounds, which
produced a bug I had thought was caused by something else.
- Hopefully fixed a long-standing occasional memory corruption
bug.
This addresses reduced visibility of scenes (as displayed in the VR
headset) that can result from the 8-bit color depth format currently
used for XR swapchain images.
By switching to a swapchain format with higher color depth (RGB10_A2,
RGBA16, RGBA16F) for supported runtimes, visibility in VR should be
noticeably improved.
However, current limitations are lack of support for these higher
color depth formats by some XR runtimes, especially for OpenGL.
Also important to note that GPU_offscreen_create() now explicitly
takes in the texture format (eGPUTextureFormat) instead of a
"high_bitdepth" boolean.

While trying to get Blender 2.93.x LTS to build fine on all release architectures in Debian, I noticed that the misleading use of "mips" as integer variable caused problems when compiling on mips64el. The patch should fix the issue.

ID data-blocks that could be accessed from Python and weren't freed
using BKE_id_free_ex did not release the Python reference count.
Add BKE_libblock_free_data_py function to clear the Python reference
in this case.
Add asserts to ensure no Python reference is held in situations
when ID's are copied for internal use (not exposed through the RNA API),
to ensure these kinds of leaks don't go by unnoticed again.
* The PBVH draw subsystem is now told whether any viewports
have drawtype >= OB_MATERIAL before anything in any windows
are drawn. There are no alternatives given the design
constraints of sculpting, where simply uploading data to the GPU
quickly becomes a bottleneck.
* Fixed flat vcol shading mode.
rBfb87d236edb7 made the values returned by `projmat_dimensions` more
standardized following the documentations. But the functions in Blender
that called `projmat_dimensions` followed a proposal that these values
corresponded to a distance of 1m of clip.
Adjust these functions to follow the new algorithm.
This patch fixes an issue with missing faces when assigning a material slot other than the first to faces on AMD TAHITI cards. Refer to T78390 and T74024 for a description of this issue.
This patch also incorporates fix from T78390 for KAVERI.

Also:
* added BMLog function to save mesh IDs.
- Used by SCULPT_UNDO_DYNTOPO_BEGIN/END instead of
saving the whole mesh, which was the previous behavior.
* SCULPT_UNDO_DYNTOPO_BEGIN no longer pushes a non-dyntopo
geomtry undo node, as this is no longer necassary.
This greatly speeds up going into/out of sculpt mode
with dyntopo enabled, as before it was copying
the mesh twice.
* PBVH_BMESH now supports faces other then triangles;
* Dyntopo triangulates faces as it finds them.
- I looked into methods of preserving quads and failed to
find anything that worked well in practice; it actually
worked better to use topology rake to align triangles
into quads and then mark diagonal edges for later dissolving
then to try to preserve quads explicitly (I've not
implementated that here, that was research code).
- To avoid excessive cache-destroying loops over vertex-faces,
DynTopo flags which verts have non-triangle faces.
* PBVHTriBuf now builds edge buffers so we can avoid drawing
tesselation phantom edges.
* BMLog also now supports arbitrary faces. It still does not
support edges though.
TODO:
* Fix vcol cell shading mode
* Make sure indexed drawing works
The crash happens because `GPU_offscreen_create` is called with `err_out` `NULL`.
This patch proposes a solution within the `GPU_offscreen_create` itself
and raises an error report in the interface if a menu is called with
dimensions beyond what is supported.

This makes node trees with long links that cross other nodes easier to work with.
Dimmed links will be ignored by various modal operators like cut and reroute insertion.

* Dyntopo now stores a list of PBVHTriBufs in leaf nodes, one per material
used by the node.
* Actual drawing buffers live in a new mat_draw_buffers PBVHNode member.
