This commit adds a node to output the convex hull of any input geometry
as a mesh, which is an enclosing geometry around a set of points.
All geometry types are supported, besides volumes.
The code supports operating on instances to avoid copying all input
geometry before the operation. The implementation uses the same backend
as the operation in edit mode, but uses Mesh directly instead of BMesh.
Attribute transfer is not supported currently, but would be a point of
improvement for the future if it can work in a predictable way on
different geometry input types.

Note that these changes are limited simple cases as these kinds of
changes could allow for errors when refactoring code when the known
state is not so obvious.
Support thread local storage for BLI_task_parallel_mempool,
as well as support for the reduce and free callbacks.
mempool_iter_threadsafe_* functions have been moved into a private
header thats only shared between task_iterator.c and BLI_mempool.c
so the TLS can be made part of the iterator array without having to
rely on passing in struct offsets.
Add test task.MempoolIterTLS that ensures reduce and free
are working as expected.

While this should not be allowed in general, there are some cases
(library overrides at least) where supporting this is mandatory.
Further more, comment stating that this could crash is from 2011, could
not reproduce any issue with current code. Commit comment was referring
to undo/redo, but in use cases here those should not affect things.
Note that in general, such relatively high-level checks should be
handled by high-level, close to user code (like in ED area e.g.), not in
low-level BKE code anyway.
This node creates a boolean face attribute that is "true" for
every face that has the given material.

Under some circumstances using task isolation can cause deadlocks.
Previously, our task pool implementation would run all tasks in an
isolated region. Now using task isolation is optional and can be
turned on/off for individual task pools.
Task pools that spawn new tasks recursively should never enable
task isolation. There is a new check that finds these cases at runtime.
Right now this check is disabled, so that this commit is a pure refactor.
It will be enabled in an upcoming commit.
This fixes T88598.

Added a new api function to stich multires grids
on specific faces in a mesh,
subdiv_ccg_average_faces_boundaries_and_corners,
and changed multires normal calc to use it.
VTune profiling showed that this was a major
performance hit once you get above 10,000 or so
base mesh faces and/or have a high number of
subdivision levels.
Here's a video comparing the difference. Note the
bpy.app_debug switch is not in the final commit.

Also use Curve as an argument instead of Object, since the object was
only used to retrieve the curve, and the calling code is already working
with curve data.
Some of the comments referenced code that was no longer there, or even
defines that were removed. Other comments were more confusing and
vague than helpful. Also adjust formatting in a few cases.
Add a call to orthogonalize the matrix before processing for the
same reasons as D8915, and an early exit in case no limits are
enabled for a bit of extra efficiency.
Since the constraint goes through Euler decomposition, it would
in fact remove shear even before this change, but the resulting
rotation won't make much sense.
This change allows using the constraint without any enabled limits
purely for the purpose of efficiently removing shear.

Since Limit Rotation is based on Euler decomposition, it should allow
specifying the order to use for the same reasons as Copy Rotation does,
namely, if the bone uses Quaternion rotation for its animation channels,
there is no way to choose the order for the constraint.

This patch exposes functionality for performing partial mesh updates
for normal calculation and face tessellation while transforming a mesh.
The partial update data only needs to be generated once,
afterwards the cached connectivity information can be reused
(with the exception of changing proportional editing radius).
Currently this is only used for transform, in the future it could be
used for other operators as well as the transform panel.
The best-case overall speedup while transforming geometry is about
1.45x since the time to update a small number of normals and faces is
negligible.
For an additional speedup partial face tessellation is multi-threaded,
this gives ~15x speedup on my system (timing tessellation alone).
Exact results depend on the number of CPU cores available.

When changing to another texture paint slot, the texture displayed in
the viewport should change accordingly (as well as the image displayed
in the Image Editor).
The procedure to find the texture to display in the viewport
(BKE_texpaint_slot_material_find_node) could fail
though because it assumed iterating nodes would always happen in the
same order (it was index based). This is not the case though, nodes can
get sorted differently based on selection (see ED_node_sort).
Now check the actual image being referenced in the paint slot for
comparison.

So far, linked IDs were not properly sorted at all, only the ones
explicitely linked from WM code would be, but any indirectly linked
data-blocks would end up in some random order in their lists.
While not ideal, this is not a huge issue in itself, but it had bad
side-effects, e.g. causing (recursive) resync of overrides to happen in
random order, leading to mismatches between name indices of newly-generated
override IDs and the one existings e.g.
And in general, it is much better to be consistent here.
Note that the file sub-version is bumped for this commit, since some
sorting (the directly linked IDs which we keep a reference to) should
never need to be re-done after relevant doversion process.
This commit adds a node that outputs the total length of all
evalauted curve splines in a geometry set as a float value.

In some cases e.g. only objects would actually need resync, so
collections on the override character would not be resynced, and if some
objects were sharing relationships with others those could be
lost/destroyed.
Ensure 'virtual' linked override IDs generated by the recursive resync
process are tagged as indirectly linked data.
This is needed to avoid the 'missing data' messages on those virtual
data-blocks after saving and reloading.
`BKE_main_collections_parent_relations_rebuild`,
`BKE_collection_parent_relations_rebuild` anf their internal
dependencies had two issues fixed by this commit:
* Main one was that a same collection could be processed several times,
sometimes even in an infinite loop (in some rare corner cases), by
`collection_parents_rebuild_recursive`.
* More exotic, code here would not ensure that the collections it was
processing were actually in Main (or a master one from a scene in
Main), which became an issue with some advanced ID management
processes involving partially out-of-main remapping, like liboverride
resync.
While encoder parameters for lossless encoding are set correctly,
output is not lossless due to pixel format being set to
`AV_PIX_FMT_YUV420P` which is inherently lossy due to chroma subsampling.
This was reported in T61569 and was merged to T57397, but there were
2 bugs - one for encoding and one for decoding.
Set pixel format to `AV_PIX_FMT_YUV444P` when rendering lossless H264
files. This format isn't available in `codec->pix_fmts[0]` and it looks,
that it has to be hard-coded.

Often you need to copy a spline to do an operation, but don't want
to manually copy over all of the settings. I've already forgotten to
do it once anyway. These functions copy a spline's "settings" into a
new spline, but not the data. I tried to avoid duplicating any copying
so this is easier to extend in the future.

Often it would be beneficial to avoid the virtual array implementation
in `geometry_component_curve.cc` that flattens an attribute for every
spline and instead read an attribute separately for every input spline.
This commit implements functions to do that.
The downside is some code duplication-- we now have two places handling
this conversion. However, we can head in this general direction for the
attribute API anyway and support accessing attributes in smaller
contiguous chunks where necessary.
No functional changes in this commit.

Add a doc-string explaining the purpose of each call back and
how they should be used.
Also add a currently unused callback 'POST_FAIL' that is to be used in
cases the action fails - giving script authors, a guarantee that a
call to `pre` will always have a matching `post/post_fail` call.
- D11422: adds a callback that can use 'post_fail'.
- T88696: proposed these conventions.
This node is similar to the mask modifier, but it deletes the elements
of the geometry corresponding to the selection, which is retrieved as
a boolean attribute. The node currently supports both mesh and point
cloud data. For meshes, which elements are deleted depends on the
domain of the input selection attribute, just like how behavior depends
on the selection mode in mesh edit mode.
In the future this node will support curve data, and ideally volume
data in some way.

Particle" coords, but was not working with other coordinates either.
Dont see a reason for not supporting Size influence textures for these
kinds of particles (and since these types of particles have an "age"

This fixes T88455 by adding an empty material slot to newly
generated meshes. This allows the object to overwrite the
"default" material without any extra nodes. Technically,
all polygons reference the material index 0 already, so it
makes sense to add a material slot for this material index.
