Integrates XR input actions with the WM event system. With this commit,
all VR action functionality (operator execution, pose querying, haptic
application), with the exception of custom drawing, is enabled.
By itself, this does not bring about any changes for regular users,
however it is necessary for the upcoming VR add-on update that will
expose default controller actions to users.
For add-on developers, this updates the Python API with access to XR
event data (input states, controller poses, etc.), which can be
obtained via the "xr" property added to the bpy.types.Event struct.
For XR events, this property will be non-null and the event will have
the type XR_ACTION.
Further details:
XR-type window events are queued to the regular window queues after
updating and interpreting VR action states. An appropriate window is
found by either using the window the VR session was started in or a
fallback option.
When handling XR events, mouse-specific processing is skipped and
instead a dedicated XR offscreen area and region (see 08511b1c3d) is
used to execute XR event operators in the proper context.

For details see the "Extending the Disney BRDF to a BSDF with Integrated
Subsurface Scattering" paper.
We split the diffuse BSDF into a lambertian and retro-reflection component.
The retro-reflection component is always handled as a BSDF, while the
lambertian component can be replaced by a BSSRDF.
For the BSSRDF case, we compute Fresnel separately at the entry and exit
points, which may have different normals. As the scattering radius decreases
this converges to the BSDF case.
A downside is that this increases noise for subsurface scattering in the
Principled BSDF, due to some samples going to the retro-reflection component.
However the previous logic (also in 2.93) was simple wrong, using a
non-sensical view direction vector at the exit point. We use an importance
sampling weight estimate for the retro-reflection to try to better balance
samples between the BSDF and BSSRDF.

There is not enough time before the release to improve Random Walk to handle
all cases this was used for, so restore it for now.
Since there is no more path splitting in cycles-x, this can increase noise in
non-flat areas for the sample number of samples, though fewer rays will be traced
also. This is fundamentally a trade-off we made in the new design and why Random
Walk is a better fit. However the importance resampling we do now does help to
reduce noise.

This commit implements T91780, adding nodes to get and set builtin
attributes. Individual set nodes are used so that the values can be
exposed for direct editing, which is useful for attributes like shade
smooth and spline resolution. Individual input nodes are used to allow
reusing nodes for multiple components, and to allow grouping multiple
outputs conceptually in the same node in the future.
Input Nodes
- Radius
- Curve Tilt
- Curve Handle Positions
- Is Shade Smooth
- Spline Resolution
- Is Spline Cyclic
'Set' Nodes
- Curve Radius
- Point Radius
- Curve Tilt
- Curve Handle Positions
- Is Shade Smooth
- Spline Resolution
- Is Spline Cyclic
Using hardcoded categories is necessary to add separators to the node

Delete Geometry:
This adds a copy of the old node in the legacy folder and updates the
node to work with fields. The invert option is removed, because it is
something that should be very easy with fields, and to be consistent
with other nodes which have a selection. There is also a dropdown to
select the domain, because the domain can't be determined from the
field input. When the domain does not belong on any of the components
an info message is displayed.
Separate Geometry:
A more general version of the old Point Separate node. The "inverted"
output is the same as using the delete geometry node.

Only count volume objects after shader optimization.
Allows to discard objects which don't have effective volume
BSDF connected to the shader output (i.e. constant folded,
or non-volume BSDF used by mistake).
Solves memory regression reported in T92014.
There is still possibility to improve memory even further
for cases when there are a lot of non-intersecting volume
objects, but that requires a deeper refactor of update
process. Will happen as a followup development.

This function now takes a depsgraph and a list of objects to avoid
inefficient O(n^2) iteration when extracting instances from all objects
in the scene. Returning an object -> instance map.
Note that keeping compatibility with the existing API wasn't practical
in this case since instances can no longer be generated from the scene
and it's objects.
The longer-term goal is to separate host-only scene update
from device update: make it possible to make kernel features
depend on actual scene state and flags.
This change makes it so shaders are compiled before kernel
load, making checks like "has_volume" available at the
kernel features calculation state.
No functional changes are expected at this point.

The problem is that the fast triangulator (based on polyfill)
sometimes makes degenerate triangles. Commit 8115f0c5bd91f had
a check for degenerate triangles but it wasn't thorough enough.
This commit uses a more thorough (and pessimistic) test for
degenerate triangles, using the exact triangulator in those cases.
This commit introduces the Align Euler to Vector function node which
rotates to a body into a given direction. The node replaces the legacy
"Align Rotation to Vector" node, which only worked on an attribute
named `rotation` internally. The "Euler" in the name is meant to make
it clearer that the rotation isn't interchangeable with a regular
vector.

Strip was flagged for deletion in `seq_transform_handle_overwrite()`
on `STRIP_OVERLAP_IS_FULL`. Then it is removed in
`SEQ_edit_strip_split()` before it should be.
Handle `STRIP_OVERLAP_IS_FULL` in separate loop.
This may not be complete solution, because in example file overlap is
caused between 2 transformed strips and one that is "static".
Such operation should not be possible in first place. This fixes the
crash at lest, so improvement in behavior can be handled separately.

- Fix a typo that used the max instead of the min for the soft max

The context menu is a standard way to expose operations of the clicked
item to the user. They expect it to be there, and we can make use of it
as a place to put more advanced operations in.
The menu contains:
* New Catalog
* Delete Catalog
* Rename
Also removes the 'x' icon to delete a catalog from the right side of a
row. This was just placed there temporarily until the context menu is
there. It's too easy to accidentally delete catalogs with this.
Tree-view items can now easily define their own context menu. This works
by overriding the `ui::AbstractTreeViewItem::build_context_menu()`
function. See the documentation:
https://wiki.blender.org/wiki/Source/Interface/Views#Context_Menus
Consistently with the Outliner and File Browser, the right-clicked item
also gets activated. This makes sure the correct context is set for the
operators and makes it clear to the user which item is operated on.
An operator to rename the active item is also added, which is something
you'd typically want to put in the context menu as well.
Enabling or disabling motion blur requires rebuilding the BVH of affected geometry and
uploading modified vertices to the device (since without motion blur the transform is
applied to the vertex positions, whereas with motion blur this is done during traversal).
Previously neither was happening when persistent data was enabled, since the relevant
node sockets were not tagged as modified after toggling motion blur.
The change to blender_object.cpp makes it so `geom->set_use_motion_blur()` is always
called (regardless of motion blur being toggled on or off), which will tag the geometry
as modified if that value changed and ensures the BVH is updated.
The change to hair.cpp/mesh.cpp was necessary since after motion blur is disabled,
the transform is applied to the vertex positions of a mesh, but those changes were not
uploaded to the device. This is fixed now that they are tagged as modified.

This bug was introduced in D12190 because the list of types that support materials did not include GPencil and this caused all materials to be removed after they were created during conversion.
If the operator poll of a superimposed icon returned `false`, the
superimposed icon would just draw normally and fail silently. Instead it
will now be drawn grayed out, plus the tooltip of the icon can show the
usual "disabled hint" (a hint explaining why the button is disabled).
This seems to happen only in a few files, and not so trivial to
reproduce from scratch.
The crash is real though, and this fixes it.
It also fix a wrong comment style that was introduced in the same faulty
commit.
