In some cases the Geometry Nodes Volume Cube generates
a Volume grid that doesn't contain any leaf nodes. This can happen
when only tiles are needed to represent the volume.
This PR changes the `empty_grid` check function to also check if
there are any active tiles in the grid before returning `true`.

Now, when link drag search is used to create new input value nodes, it
also moves socket values into node storage. This means, by design, that
result of evaluation on node tree will not be changed. For data blocks,
the original value is set to null, thus avoiding the existence of
unused pointers.
Right now a few nodes (in shader in many cases) are implemented without
node storage, but by storing value in socket itself. Float value input
node is unsupported in this way too.

Found investigating #107420.
Steps to reproduce were:
- remove all objects from the scene
- add rigid body world
- bake
- crash
BKE_ptcache_bake would assume a cache can always be found, but with an
empty rigid body world this is not the case -- accessing flags would then
crash.
Now just check if we actually have a cache.
Pull Request: https://projects.blender.org/blender/blender/pulls/107537
`ptcache_baker_create` falsely assumed the PointCache owner id is always
an **object**, but when baking rigid body world it is a **scene**. Code
would cast the ID to an object and passed that to `BKE_ptcache_id_find` /
`BKE_ptcache_ids_from_object` (which can get terribly wrong -- reading
_something_ on the scene as something from the assumed object).
Prior to f61ff22967 this was less likely to be a problem, but that
commit introduced a `DrawDataList` into the `struct Scene`. In the file
from the report, this would lead to `foreach_object_particle_ptcache`
now recognizing garbage memory as a particle system, accessing its
`ParticleSettings` `phystype` would then crash (buffer-overflow).
Now pass a NULL object to `BKE_ptcache_id_find` in case we are having a
scene, following code still handles rigid bodies just fine (the scene is
actually passed separately as well).

Vulkan spec only wants to have a single aspect bit when a texture
contains both a stencil and a depth part. As for Blender depth
is more used than stencil we standardize to depth aspect.

In some cases, some partial resync roots would be missed during the
partial resync process, leading to incomplete resync of all the needed
data.
This was caused by tagging some liboverrides for resync _after_ they had
already be evaluated as part of parenting hierarchy of other
liboverrides. Fix is simply to split both steps apart, such that all IDs
that need it are tagged to resync first, and then hierarchies are
evaluated to find the required partial resync roots whithin a hierarchy.
This commit mainly addresses issues when a part of an override hierarchy
does not match anymore the linked reference data, and gets isolated form
the hierarchy root (there is no parenting chain to the root anymore).
The typical case being an object or sub-collection being moved to
another subcollection in the linked data.
Case identified while working on some Pets production files.
Note that in some cases this isolated chunk of the hierarchy will be
linked back into the appropriate place, in others it should be fully
removed (instead of staying as unused data). The later will be handled
in a another future commit.
This commit mainly detect and use a new tag for such cases, and correct
the checks to take it into account.
It also does a bit of cleanup, and replaces some asserts by `CLOG_ERROR`
reports.
Due to index-only referencing in insertion of new NLA tracks in
liboverride data, it may happen that the source of an inserted track
cannot be found.
This index-only based handling of NLA tracks in liboverrides is very
weak, in the future this will be solved by ensure uniqueness of their
names, then name-based reference can be used instead, as already done with
modifiers, constraints, etc.
Code was exposing apparently internal functions to the public header, so
it could reuse it in other View2D files. Worse even, a struct was
defined twice in different source files and they would have to be kept
in sync, just because there is no shared header file.
Such internal header files are useful and don't really cause any harm.
This fixes a crash where merging vertices by distance leads to a crash since
0652945dbd. The change did not cause
the bug though, it just made the underlying issue visible.
The issue was that `kdtree_order` assumed that the `KDTreeNode.index` didn't
have gaps, i.e. every index in a certain range is used. However, that is not the
case when only a subset of the vertices of a mesh are added to the kdtree.

This change is required for 0001485365. File version bump was included
in PR but it was behind the main branch. In main, version was updated
by 5d0595fded.
get_index_dir passed in the wrong size, also remove strange use of
BLI_path_split_dir_file which copied the directory into `file`,
only to overwrite it with the `file` afterwards.
Modifier name is being displayed as label in panel header which has restricted
the editing of it. This PR will allow to change the name of F-curve modifier
by exposing string property "name"
Included versioning code for modifier name. This will add suffix to the name if
multiple instances of same modifier exists in modifier stack.

A regression since 2d2f4d9d28: the sculpt session is re-used by the
weight paint, so changes to semantic in one place requires same
changes in another.
Before the change the `original` was intiialized to false (due to the
clear-alloc), but after the change it was the accum with an inverted
meaning which was initialized to false.

The existing tooltip of Clear Constraints modifier in object mode
(`object.constraints_clear`) didn't match its functionality. It said it
works only on the active object, but it affects all selected objects.
Hence, the tooltip has been changed from 'Clear all the constraints for
the active object only' to 'Clear all the constraints for the selected
objects'.
Also the tooltip for 'Clear Pose Constraints' in Pose Mode was updated
for consistency with the above update.

The length passed to IDP_NewString included the nil terminator
unlike IDP_AssignString. Callers to IDP_AssignString from MOD_nodes.cc
passed in an invalid size for e.g. There where also callers passing in
the strlen(..) of the value unnecessarily.
Resolve with the following changes:
- Add `*MaxSize()` versions of IDP_AssignString & IDP_NewString which
take a size argument.
- Remove the size argument from the existing functions as most callers
don't need to clamp the length of the string, avoid calculating &
passing in length values when they're unnecessary.
- When clamping the size is needed, both functions now include the nil
byte in the size since this is the convention for BLI_string and other
BLI API's dealing with nil terminated strings,
it avoids having to pass in `sizeof(value) - 1`.
In some cases comments at the end of control statements were wrapped
onto new lines which made it read as if they applied to the next line
instead of the (now) previous line.
Relocate comments to the previous line or in some cases the end of the
line (before the brace) to avoid confusion.
Note that in quite a few cases these blocks didn't read well
even before MultiLine was used as comments after the brace caused
wrapping across multiple lines in a way that didn't follow
formatting used everywhere else.
This was the code-style Blender used before switching to clang-format
which did not support this style of brace placement at the time.
Since then support was added, this helps readability as the beginning
of braces isn't as clear in the case of multi-line conditionals.
This implements a proposal from #75956.
In some cases the node didn't reproduce the same results given the
same input. Based on the test results (just 2 very detailed cubes
and a transformation), it doesn't seem to affect performance that
much. Credit to @MMMM who pointed out this option.

cc623ee7b0 did not consider some implications such as the habit of
users initiating transform operations just to change the size of the
Proportional Edit.
Therefore, partially revert the cc623ee7b0.
There were a few issues, but they mostly came from the fact that some
versioning was done in the "after linking" versioning, which came after
the regular legacy mesh conversion. Also, the `MFace` array wasn't
necessarily part of CustomData for some very old files.
The `BKE_mesh_strip_loose_faces` function was moved because it now
uses the deprecated `me->mface` pointer.
This PR addresses issue “USD export does not respect opacity threshold for clip alpha blend mode #107062”
This commit extends the USD Preview Surface material support to author the opacityThreshold attribute of materials on export, when the Alpha Clip blend mode is selected.
When authoring alpha cutouts in Blender, one sets the Blend Mode to "Alpha Clip", and the Clip Threshold to some value greater than zero.
When this case is detected on export, we now author the opacityThreshold attribute to match the specified clip threshold.
Note that opacityThreshold is already handled correctly on import, so this change allows the feature to be fully round-tripped.
