`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.
NLA track option buttons (lock track, etc.) now no longer respond to
clicks when they are hidden.
The bug stems from the fact that there was duplicate input handling
going on for the buttons: once in the normal button UI system, and then
again in the `mouse_nla_channels` function. The logic in
`mouse_nla_channels` does not inspect whether or not the setting button
is there or not, it just assumes that it is.
This function should no longer be handling mouse input for buttons
(there is even comment suggesting that the button handling to be
deprecated) since the button UI system already handles it. Therefore,
the button handling code has been removed from that
`mouse_nla_channels`.
In addition, the redundant mouse button handling for pressing the "Push
Down Action" button has also been removed from this function as well.

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.
The purpose of this patch is to add the option to create a color
attribute paint slot from the canvas selector when in material mode.

Adds an example python script to the documentation for the 3D_IMAGE shader.
The **use-case** is to draw textures with 3D vertex positions, in XR views as well as non-XR views (in a simpler manner).
**Testing**: I've tested that this compiles and works on my Macbook (with the example python script included in this change). I don't have access to a Windows or Linux machine right now, but this change doesn't look platform-specific and no new glsl shaders have been added or edited by this change. I'll try to get access to a Windows machine, but if someone does have one, I'd be really grateful if they could try this change. Thanks!
**Problem addressed**: The existing 2D_IMAGE shader (exposed in the python API) gets near-clipped when drawn in the
XR view, regardless of the near-clip settings. Additionally, the 2D_IMAGE shader only accepts 2D
positions for the image vertices, which means drawing textures in 3D requires providing
2D coordinates and then pushing a transform-rotate-scale matrix to the GPU, even for
non-XR (i.e. WINDOW) views. The 3D_IMAGE shader is simpler: it accepts 3D vertex positions, and doesn't require
any additional work by the scripter.
**Workaround**: The current workaround is to use custom shaders in the python script.
**Non-intrusive change**: No new glsl shaders were added. This change just bundles two existing shaders: the vertex shader used
by the 3D_IMAGE_MODULATE_ALPHA shader, and the fragment shader used by the 2D_IMAGE shader.

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.
The use-case is to allow an event handler (in C or a plugin) to
distinguish which hand produced the XR event.
The alternative is to register separate actions for each hand (e.g.
"trigger_left" and "trigger_right"), and duplicate the device bindings
(Oculus, HTC Vive, etc) for each action. Other than the problem of code
duplication, this isn't conceptually efficient since "trigger_left" and
"trigger_right" both represent the same event "trigger", and the
identity of the hand that produced that event is just a property of
that event.
Adds two string fields to the XrEventData called user_path and
user_path_other. The user_path_other field will be populated if the
event is a bimanual one (i.e. two-handed). This follows the pattern
used by the rest of the XrEventData struct for bimanual events (e.g.
state, state_other).

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.
Fixes T95428.

When using GCC, clang-tidy will still use clang under the hood but GCC
flags will still be passed. Therefore we will ignore any warnings about
unrecognized flags as we don't care about this when running clang-tidy.
This extends the existing object type conversion operator.
Currently, it is limited to converting to curves when the evaluated
source mesh actually has curves. This might not be the case when
it is converted to a mesh by some modifier during evaluation.

This patches rewrites the GPU shaders of curve nodes for easier future
development. This is a non-functional change. The new code avoids code
duplication by moving common code into BKE curve mapping functions. It
also avoids ambiguous data embedding into the gradient vectors that are
passed to vectors and reduces the size of uniforms uploaded to the
shader by avoiding redundancies.
This is needed in preparation for the viewport compositor, which will
utilize and extend this implementation.

Add support for volume (OpenVDB) USD export:
- Allows to export both static and animated volumes.
- Supports volumes that have OpenVDB data from files or are generated in
Blender with 'Mesh to Volume' modifier.
- For volumes that have generated data in Blender it also exports
corresponding .vdb files. Those files are saved in a new folder named
"volumes".
- Slightly changes the USD export UI panel. "Relative Texture Paths"
becomes "Relative Paths" (and has separate UI box) as the
functionality will now apply to both textures and volumes. Disabling
of this option due to "Materials" checkbox being turned off has been
removed.
