Complex Solidify creates edge bevel weights on the rim if the
according vertex has some vertex bevel weight. If there are no
edge bevel weights, they were left disabled even if vertex bevel
weights are used.
Some curve objects don't have an evaluated mesh at all, but line art
currently assumes that all curve objects have one before converting
it to a mesh internally. Fix this by checking if the curve object has an
evaluated mesh before skipping it.
The remaining problem is that evalauted from non-mesh objects or
evaluated curves from non-curve objects, etc. will be ignored if
"Allow Duplicates" is off. That's a different problem though.

Disable binary archives on Apple Silicon (issue stems from instancing multiple PSOs from the same binary archive). Pipeline creation still filters through the OS shader cache, mitigating any impact on setup times after the initial render.

This is part of the project of converting `MVert` into `float3`.
(more details in T93602), The pbvh update flag is removed and
replaced with a bitmap stored in the PBVH structure. This
patch is similar to D13878. This is mainly setup for an eventual
performance improvement by removing the extra data from
mesh vertices, but if it's consistent with testing in the other patch
doing the same thing for another "temp tag", then it may actually
increase the speed of sculpt code slightly, since less memory needs
to be loaded when checking/changing the flags.

The main issue is that the image and image user is not updated correctly
in `rna_ImageUser_update`. `BKE_image_user_frame_calc` does not set the
correct frame, because the image is null. Also `IMA_GPU_REFRESH` is not
set for the same reason.
When gpu materials are first created, it is expected that the frame is set
correctly, and the flag is set if necessary. Therefore, somewhere during
depsgraph evaluation, those have to be updated. The depsgraph node
to do the update existed already. Now there is a new relation so that it is
executed when the node tree changed, not only when the frame changed.
This is partially caused by a stupid mistake in cfa53e0fbeed7178c78
where I missed initializing the `vert_normals` pointer in
`MResolvePixelData`. It's also caused by questionable assumptions
from DerivedMesh code that vertex normals would be valid.
The fix used here is to create a temporary mesh with the data necessary
to compute vertex normals, and ensure them here. This is used because
normal calculation is only implemented for `Mesh` and edit mesh, not
`DerivedMesh`. While this might not be great for performance, it's
potentially aligned with future refactoring of this code to remove
`DerivedMesh` completely. Since this is one of the last places the data
structure is used, that would be a great improvement.

While applying liboverrides on linked data, RNA code (in
`rna_property_override_check_resync`) would detect a lot of false positive
regarding IDs needing resync, because the temporary ID used to apply
overrides was always local, breaking the libraries comparison check.
NOTE: that whole 'apply liboverrides' code could use some refreshment,
it did not change much from initila version several years ago, we now
have better tools and control over non-main data.
But for now the 'trick' in that commit should do the job, ultimately
those temps IDs should never be put in Main at all.
The crash was happening when the mesh had loose edges.
Loose edges are not part of OpenSubdiv topology and hence should not be
communicated to the refiner. Pass ta boolean flag indicating whether an
edge is loose or not in the mesh foreach routines, which seems to be
the easiest way.
Decouple the reference (linked) root ID and the hierarchy (override) root ID.
Previous code was assuming that the reference ID was always also tagged
for override creation, which is true in current master, but cannot be
assumed in general (and won't be true with partial resync anymore).
Also add asserts to validate conditions that the reference/hierarchy_root
variables must meet.
There are two things achieved by this change:
- No possible downcast of size_t to int when calculating motion steps.
- Disambiguate call to `min()` which was for some reason considered
ambiguous on 32bit platforms `min(int, unsigned int)`.
- Do the same for the `max()` call to keep them symmetrical.
On an implementation side the `min()` is defined for a fixed width
integer type to disambiguate uint from size_t on 32bit platforms,
and yet be able to use it for 32bit operands on 64bit platforms without
upcast.
This ended up in a bit bigger change as the conditional compile-in of
functions is easiest if the functions is templated. Making the functions
templated required to remove the other source of ambiguity which is
`algorithm.h` which was pulling min/max from std.
Now it is the `math.h` which is the source of truth for min/max.
It was only one place which was relying on `algorithm.h` for these
functions, hence the choice of `math.h` as the safest and least
intrusive.

This implements the update cache described in T95401.
The cache is currently only used for drawing strokes and
sculpting (using the push brush).
**Note: Making use of the cache throughout grease pencil will
have to be done incrementally in other patches. **
The update cache stores what elements have changed in the
original data-block since the last time the eval object
was updated. Additionally, the update cache can store multiple
updates to the data and minimizes the number of elements
that need to be copied.
Elements can be tagged using `BKE_gpencil_tag_full_update` and
`BKE_gpencil_tag_light_update`. A full update means that the element
itself will be copied but also all of the content inside. E.g. when a
layer is tagged for a full update, the layer, all the frames inside the
layer and all the strokes inside the frames will be copied.
A light update means that only the properties of the element are copied
without any of the content. E.g. if a layer is tagged with a light
update, it will copy the layer name, opacity, transform, etc.
When the update cache is in use (e.g. elements have been tagged) then
the depsgraph will not trigger a copy-on-write, but an update-on-write.
This means that the update cache will be used to determine what elements
have changed and then only those elements will be copied over to the
eval object.
If the update cache is empty or the data block was tagged with a full
update, we always fall back to a copy-on-write.
Currently, the update cache is only used by the active depsgraph. This
is because we need to free the update cache after an update-on-write so
it's reset and we need to make sure it is not freed or read by other
depsgraphs.

Simple upgrade of OpenXR to 1.0.22, following the steps from
https://wiki.blender.org/wiki/Source/OpenXR_SDK_Dependency and
rBb69ab42982a1. No changes to Blender code were necessary, only a version
bump.
The primary motivation for this upgrade is to utilize the
`XR_HTCX_vive_tracker_interaction` extension introduced in ver. 1.0.20.
However, the latest release (1.0.22) also adds a number of potentially
useful extensions such as:
- `XR_FB_render_model`
- `XR_HTC_facial_expression`
- `XR_HTC_vive_focus3_controller_interaction`

Turn off "Sync Length" when splitting an NLA strip.
The NLA Strip-Action Clip has a setting called "Sync Length" that is on
by default and helps to update the length of the clip to the current
actions keyframes so the strip shows the entire actions stored
animation.
When you split one of these strip-action clips in the NLA to trim it
shorter or to move it somewhere else in the NLA tracks to blend or work
with, the "Sync Length" setting stays checked on. You can have many
strips in the NLA that all look to the same action, if you split one
strip , you now have two strips showing or linked to the same action.
To see or edit keyframes on a strip, you enter tweak mode. When you exit
tweak mode, if "Sync Length" is active on the strip-action clip
settings, the strip length is changed/reset to match the action keys.
When you have many clips, this causes all of them to evaluate and update
no matter where they are in the NLA. This destroys/undoes all the user
work to trim down and place the clips in the NLA.
**Description of the proposed solution:**
This patch/change would turn off, the "Sync Length" setting when the
split tool was used on a strip/action clip to help protect the users
choice to trim and keep the clip that length. It doesn't change the
ability to turn the setting back on or off, it just makes sure that the
user doesn't accidentally or unknowingly loose work.
The same process happens when an action is created that has a "manual
range" set that is different than the length of the actions start-end
keyframes. It makes sense to do the same thing for the split tool.
**Alternative solutions:**
While the user could know this and turn off this setting by hand, it is
easy to forget and or the user might think that it only happened to the
one clip they were editing and not realize it happened to all the
trimmed versions, changing the users choice without the user knowing it
happened.
**Limitations of the proposed solution:**
It only fixes the split tool, if another tool was created and some how
impacted the clip length we would need to have that tool also take the
sync length into account.

From a strict language point of view the code required a braces around
`trgba` initialization. But it is easier to rely on the fact that fields
which are not specified are zero-initialized.
Under some circumstances, simply adding a curve object and going
to edit mode would cause a crash. This is because the evaluated
`CurveEval` was accessed but also freed by the dependency graph.
The fix reverts the part of b76918717dbfd8363f that uses the
`CurveEval` for the curve object bounds. While this isn't ideal,
it was the previous behavior, and some unexpected behavior
with object bounds is much better than a crash. Plus, given the plans
of using the new "Curves" data-block for evaluated curves, this
situation will change relatively soon anyway.
Strip aligning wasn't done when length of 2 strip is equal, but since
these strips are aligned according to position in stream this can
produce offset.

- No possible downcast of size_t to int when calculating motion steps.
- Disambiguate call to min() which was for some reason considered
