Knife projection BVH-tree lookup could use invalid indices since the
mesh being cut is also used for BVH intersection tests.
Solve by storing triangle indices when knife project is used so a
triangle index can always be used to look up original coordinates of a
triangle.
This is caused by the geometry shader used by the edit mode line drawing.
If the drawcall uses indexed drawing and if the index buffer only contains
restart indices, it seems the result is 1 glitchy invocation of the
geometry shader.
Workaround by tagging these special case index buffers and bypassing
their drawcall.
Assume geometry is always potentially animated, since we can't use our heuristic
to detect if the object is potentially animated by looking at modifiers on the
object.
The main original reason for this check was to avoid evaluating subdivision
surfaces for many static objects, which is not happening here anyway.
New OBJ exporter is missing "Path Mode" setting for exporting .mtl
files. The options that used to be available were: Auto, Absolute,
Relative, Match, Strip Path, Copy. All of them are important. The new
behavior (without any UI option to control it) curiously does not match
any of the previous setting. New behavior is like "Relative, but to the
source blender file, and not the destination export file".
Most of the previous logic was only present in Python based code
(bpy_extras.io_utils.path_reference and friends). The bulk of this
commit is porting that to C++.

Code was not really designed to hanlde corrupted (e.g. local ID) root
hierarchies, now it should handle better those invalid cases and restore
proper sane situation as best as possible.
Fixes crashes with some corrupted files from Blender studio.
Use the same method for node selection and dragging that is used
in the 3D viewport and UV editor. Instead of relying on a modal
operator - use the keymap to handle click/drag events.
Details:
Failure to transform unselected nodes was caused by [0] & [1] however
detecting drag relied on specific behavior which I don't think we should
be depending on.
This error happened when selection was defined both in the key-map for
the tool and for the node-editor.
- The left mouse button would activate selection in both the tool
and "Node Editor" keymap.
- The first selection would return `FINISHED | PASS_THROUGH` when
selecting a previously unselected node.
- The same PRESS would trigger a second selection would return
`RUNNING_MODAL | PASS_THROUGH`,
(starting a NODE_OT_select as a modal operator).
- In 3.1 (with tweak events) the modal operator would then exit and
fall-back to the tweak event which would transform the selected
nodes.
- In 3.2 (as of [0]) the PRESS that starts the modal operator is
considered "handled" and prevents drag event from being detected.
The correct behavior in this case isn't obvious:
If a modal operator starts on pressing a button, using that same the
release to generate drag/click events is disputable.
Even in the case or 3.1 it was inconsistent as tweak events were
generated but click events weren't.
Note: after investigating this bug it turns out a similar issue already
existed in 2.91 and all releases afterwards. While the bug is more
obscure, it's also caused by the tweak event being interrupted as
described here, this commit resolves T81824 as well.

Some drivers completely forbid quote characters even in unused
preprocessor directives.
This patch adds a debug build check for all `.glsl` files that need to
be manually handled. For shared headers with `#include` directives, we
need to do runtime patching of the source to remove the quote.
Also fix an instance of the quotes check failing in `eevee_next`.
This was caused by the `Closure` members being added to the final contribution
more than once. The workaround is to clear the members once a closure has
been added to the final contribution. I used `inout` on `Closure` inputs
so that the render engine implementation of mix and add closure nodes
can do its own thing. The nodegraph handling of inout was changed for this
to work.
OCIO could build before pystring and imath due to
OCIO missing the dependencies on these two projects
No rebuild required as the build would have failed

Curve tangent was correctly mistaken with curve normal.
This patch fixes the name of the output in the glsl function and make curve
attributes more explicit (with `curve_` prefix).
This also improve the normal computation by making it per pixel to match
cycles.
Also ports the changes to eevee-next.
The previous 3.1 libraries (accidentally) used glApi instead of GLEW and were
working for GPU subdivision, so revert to that. There's a suspected conflict
with Blender's own bundled GLEW or other issue with GLEW, causing the crash in
T97737.
The current GPU subdivision implementation does not need OpenCL, CUDA or GLFW.
So also remove libraries needed for that. It's simpler to stick to compute
shaders in OpenGL/Vulkan/Metal and not involve additional APIs.

The mesh drawing code used a different mesh to check whether or not to
draw face dots and to actually retrieve them. The fix is moving the
responsibility of determining whether to use subsurf face dots to the
creation of `MeshRenderData` where the mesh used for drawing is
known, rather than doing it at a higher level.

`TEMPERATURE` type was also missing, not only the new-ish
`TIME_ABSOLUTE` one...
Added a static assert on the size of the `bpyunits_ucategories_items`
array, and a comment on anonymous enum of `B_UNIT_`, in the hope this
won't happen again in the future.
On certain systems when eevee is used in a 3d viewport could crash. It
happened more often on slower systems or systems with slower glsl compilers.
For example an Intel Mac Mini. The cause was that even if a GPUMaterial
was in used it could be freed.
For some reasons the mipmap count was not set to max during creation.
Probably it was mistaken with the UDIM tilemap texture which is only
1D and has only one mipmap.
This is because some drivers / GPU actually still do double buffer swapping
but others don't. Adding this do ensure the background color of the first
redraw.
Note that this fix was not tested on the problematic hardware and might not
solve the issue.
This was because the alpha clip thresholding was previously done in the
material nodes codegen. Now it is the responsibility of the engine to
implement it.
This adds a loose uniform that is set by EEVEE itself to control the clip
behavior.
Makes the File Browser filter by .obj and .mtl files by default again. Note
that this commit focuses on fixing this specific bug, further
refactors/tweaks/fixes are planned (see D14863).

When resizing a viewport all engine instance data was cleared.
This wasn't the intended design and lead to performance regressions
in the image engine.
This patch makes sure that the instance data isn't cleared when
the viewport size changes. When using instance data, draw engines
are responsible to update the textures accordingly.
This could also reduce flickering/stalling when resizing the viewport
in eevee-next.
