Reset the 'hierarchy index' runtime `temp_index` value for all library IDs.
This prevent the assert to be triggered when trying to rebuild libraries
hierarchy and there are some orphaned (i.e. not used by anything) library IDs
around.
If points are beind the camera, we don't really want to erase them. This
patch marks invalid coordinates thus preventing them from intersecting
with a eraser.
The reason for using a large value to indicate "invalid coordinate"s are:
- No need to further break down the way we process `src_to_dist` point matching array for `hard_eraser` `soft_eraser`, makes the entire logic much easier.
- No eraser is gonna be touching such a large coordinate of `1e20`.
Technically there's this case where if a segment crosses the near or far clipping plane (to handle this correctly, you'll need to split that segment into two at the clipping plane position and it increases complexity a lot), and then you will have undefined erasing behaviour, however the worse case is that the one segment was completely removed, and in such case I think it's acceptable.

Remove the `anim.slot_new_for_object` operator. It's no longer in use, and
replaced by the more generic `anim.slot_new_for_id` operator.
The latter is also coded in Python, and easier to follow than the code it
replaced.
No functional changes.

After pushing down the Action to the NLA, it needs to be tagged for
reevaluation. The code was using `adt->action->id` for this, but since
the nature of the operator is that it un-assigns the Action itself, that
would always be a null pointer.

The API did not initialize the `curve_type` for the newly created strokes resulting in unwanted behavior.
Set the curve type to the expected default: `POLY`.

Adds an additional precheck to identify if the app cache dir is correct.
Reduces placing cache files all over the place when the app dir isn't
correct.
Adds a SPIR-V cache that skips frontend compilation for shaders
that are already compiled in a previous run of Blender.
Initially this was postponed to 4.4 but it was observed that
the vulkan backend didn't perform well on Windows in debug
builds. The reason is that the compiler would also be a debug
build which makes compiling a shader really slow. Starting
Blender on a debug build could take minutes.
So the decision was made to give this task a higher priority so
the vulkan backend would become more usable to developers
as well.
The cache is stored in the application cache dir. The SPIR-V
binaries can be used by different Blender versions so there
is no version specific cache folder.
**Sidecar**: SPIR-V files are a stream of bytes. There is no
header information that allow us to validate the stream. To
add basic validations we could add our custom header or
a sidecar. It was chosen to use a sidecar as having the SPIR-V
files unmodified allows us to load them directly in
debug tools for analyzing.
**Retention**: Shaders that are not used are automatically
removed with a retention period of 30 days.
**Shader builder**: Shader builder cannot use the SPIR-V
cache as it uses stubs that returns invalid cache directories.
This would load/save the cache to the location where you
started the build.

This was located in BKE_appdir which is higher level
(used for accessing Blender's paths), where as the home directory
may be accessed from lower level path code.

Unlike many other brushes, the Layer brush uses the original coordinates
of a given vertex only for the distance test when calculating the factor
and does not use it for other components such as textures.
Note that this commit looks larger than the change would imply, as it
required undoing a recent refactor that is no longer applicable with the
distance changes.

We no longer keep the active_vert value in a valid state when the cursor
is not over the mesh. The helper method to access this position can
thus result in incorrect behavior when storing and retrieving this
value.
In this case, we simply avoid setting the `UnifiedPaintSettings` values
related to the last stroke, so that when it is used in
`view3d_navigate.cc` it falls back to the object origin.

Fixes a crash caused by a null pointer dereference when the Mesh Filter
tool with Erase Displacement option is used on a mesh that has no
Multiresolution modifier.

This fixes#127629. It's still a bit slower than it used to be when there are
lots of instances, but that fixes the main bottleneck that was introduced in
#116582. The issue was that we iterated over all attributes of all instances,
but it should only be necessary to iterate over the instances of each unique
geometry only once.
There is still quite some optimization potential in the Realize Instances code
for the case when realizing lots of instances. Especially the code to gather all
geometries that should be realized can still be made more efficient by reducing
redundant work and using multi-threading.

Before version 4.1, the vertex destination during edge sliding for two
independent edges was always the midpoint of the vertices closest to
those edges.
In version 4.1, this behavior was improved to calculate the destination
based on the intersection of the edges. However, when the faces were
coplanar, the behavior would revert to the previous midpoint
calculation instead of using the intersection.
This fix ensures that the vertex destination consistently aligns with
the intersection point, even when the faces are coplanar.
In non-manifold geometry, the original loop could fail to identify the
correct slide direction because it checked for loop equality
(`l_other != l_edge`), which might never be met.
The condition has been revised to check for face equality
(`l_other->f != l_edge->f`), ensuring the loop terminates correctly and
preventing infinite iterations in problematic geometry cases.
Blender crashes when using the GPU compositor sometimes. This is because
compositor render data was accessed before it was updated in the
realtime compositor when detecting compositing device. So fix that by
first updating compositor data before calling any context methods.
