Mistake in 437cb33a73.
Found while investigating #129504. Personally I don't notice
a change in behavior, but the original code, as convoluted as it
was/is, clearly tried to iterate over neighbors of neighbors rather
than iterating over neighbors twice.

For cases where a small fraction of a PBVH node is processed,
missing skipping of vertices outside of the brush radius causes
a noticeable regression. Typically we tried to avoid this sort of
filtering because it should be redundant with lowering the BVH
node size and it interferes with some other code simplicity goals.
But adding factor filtering back is a very small change.
Prior to this commit, there was an attempt to remove extra data stored
at the Sculpt Undo `Node` level, specifically an extra position array
used when a deform modifier was in the stack.
The prior commit attempted to perform the undo step by calculating a
translation between the current positions and the previous unode
position and using that as the input to the deformation process.
However, this resulted in the undo not being completely applied to the
mesh and the data remaining in a weird state.
To fix this, this commit reintroduces some previously removed functions
and constructs to perform this restore step by swapping data if
necessary. We choose to not simply revert the change that applied this
as we want to eventually reinvestigate this path, but for the imminent
4.3 release, it makes more sense to restore previous behavior.

The topology island cache needs to be freed when changing multires
levels so that it can be recalculated and be valid for a given level. To
fix this, this commit adds the `invalidate` call to the
`BKE_sculptsession_free_pbvh` method, which consolidates similar
lifecycle behavior.

`select_handle` operator did return passthrough when retiming key was
selected. This was incorrect behavior. To prevent translating retiming
keys, retiming selection must be cleared as well.

Prior to this commit, the brush action was determined on a step by step
basis by peeking at the `StrokeCache` `bstrength` property and
determining which brush to use based on if the value was negative or
not. The sign of this value, however, was not static across the
entirety of a brush stroke, as it is calculated from three separate
fields, one of which could vary over the course of a stroke when using a
tablet, the `pen_flip` property.
To fix this issue, this commit ensures the `pen_flip` field is only
updated at the beginning of the stroke and also adds a new boolean to
store the initial direction of the stroke to reduce further ambiguity
when comparing the sign of the brush strength.

With the introduction of brush assets, there are now two reasons that
motivate turning this setting on by default.
* More paint brushes - Previously, there was a single paint brush in
Sculpt mode, this made the setting for general usage less needed when
compared to the 10 brushes that are now included in the essentials
pack
* Brush settings are lost on reload - Unless the changes to a brush are
saved to the asset as a default, the color for a brush is now no
longer persisted between Blender sessions. It makes little sense to
save a specific color for a specific brush on the asset level unless
it is needed for the brush functionality.
This commit ensures that the appropriate Scene flag is set for the
unified color and defines the default primary and secondary colors as
000000 and FFFFFF, respectively.

Introduced by 5fff95f519.
The issue was that the `edit_points_vflag` buffer is of size `total_points_num`
which is based on the number of control points not evaluated positions.
The fix is to use `points_by_curve` instead of `points_by_curve_eval`
to get the right start and end indices.

Sorting assets by catalog was introduced for the asset shelf in
471378c666. Intention was to keep related/similar assets closer
together. But the sorting was based on the catalog name only, so
the catalog order didn't make much sense, and closer related assets
would still end up being separated by less related ones.
Instead the full catalog path should be compared, so that the hierarchy
is reflected better, and for example sibling catalogs follow each other.
This way related assets are actually placed in close proximity, as
initially intended.

When the modifier is disabled with level 0, the corner_vert array
wasn't properly created in the subdivided mesh. The simplest
solution is to just skip the subdiv processing for the unwrap when
the level is 0 and nothing would happen anyway.

Unwrapping warned that a non 0/1 boolean value was being set.
Initialize all members of PVert since they would be accessed
when duplicating a PVert causing the uninitialized memory to be read.
This "update object for edit" call is incorrect because it retrieves the
evaluated state for the object that the undo itself invalidates. The
object/modifiers must reevaluate before we rebuild the deformation
matrix array (which is the operation causing the crash).

The Cryptomatte node produces a bad output when the viewport is in
camera view. That's because compositing is limited to the camera region
in that case, but the node assumes the full viewport size. To fix this,
only consider the compositing region instead of the full viewport.

Prior to this commit, the PBVH partitioning process did not work
correctly for multires meshes with materials. Specifically, it failed
upon mapping the partitioned faces into their corresponding corners.
The rough process here is as follows:
* Flatten out the array of face indices into an array of corner indices.
* Sum up each `GridsNode` `prim_indices` corner count into an array.
* Create an `OffsetIndices` from these sums
* Use the `OffsetIndices` to slice the array created at the beginning
to assign to each node.
However, this process requires that the main PBVH array of corner
indices has the same order as iterating over the nodes, which the
partitioning algorithm does not do.
To solve this, this commit iterates over the Node `prim_indices` `Span`s
in the same order that the nodes are stored when flatting out the
corner data, ensuring a correct mapping.

The length checking wasn't accounting for null bytes within multi-byte
sequences and could step over the null bytes.
For BLI_strlen_utf8 this could result in an out of bounds read.
In practice most UTF8 data is validated so the extra checks
are mainly to prevent errors on invalid or corrupt UTF8 text.
Python scripts could perform actions that created notifiers
which would not be handled until the script was complete.
In the case of adding & removing objects a notifier would be created
for adding the object, then cleared when the ID was removed.
This lead to the notifier queue filling up with cleared notifiers
which were included in the search whenever an ID was removed.
The result of this was that adding and removing objects from a script
would become increasingly slower & use more memory.
Resolve by storing the current notifier being handed which isn't freed
(only cleared). The notifier handling loop detects cleared notifiers
and frees them after use.
Remove a workaround for #23871 which manipulated the module
to prevent classes defined in the text editor from having their
name-space cleared.
This caused the "multiprocessing" module to store the "__main__" module
as "__mp_main__" for later use.
Accessing attributes from this module would then attempt to read from
with a null "mp_dict" which crashed. This happened when showing the
extensions preferences but would have occurred if "__mp_main__" was
accessed from elsewhere too.
Resolve by removing the workaround since it has not been needed
since Python 3.2.
Meta-data are missing on Cryptomatte layers in the GPU compositor, so
they do not get saved using the File Output node. This is due to a use
after free error where a temporary string is used in the meta-data
population logic. This is fixed by assigning the string to a temporary
variable instead.
Thanks to Jorn Visser for finding the cause of the issue.
In GPv2 the parentinv matrix is zero initially and only becomes valid
after setting the layer parent. This matrix must not be copied to the
GPv3 layers unless the parent is set.
In addition the parentinv matrix should also be computed when changing
the layer parent. This has been nominally added, except that a full
computation isn't possible without the actual grease pencil Object. This
means a local RNA property cannot update the parentinv matrix, this
needs to become a full-blown operator. The behavior now should be the
same as in GPv2 at least.

Even though this is generally avoided, drivers don't prevent
invalid values being set. Further files from branches or files
written in the future may contain enum values not yet known.
Resolve by range checking enum values which are used to index arrays.
RNA label & description truncation could cause invalid UTF8
which caused BLI_string_search to hang.
Resolve by ensuring truncation of RNA descriptions & labels never
truncates a multi-byte sequences.
The issue with BLI_string_search would still be good to resolve but can
be handled separately.
Since GPv3 shader currently uses particle strand/points shader, we
need to modify that slightly to display the grease pencil overlays.
This adds the missing `vflag` attribute to the edit gpencil batch.

Addresses the case when Blender is shutdown before the
parallel compiler has finished processing all the shader batches.
The parallel compiler destructor will now attempt to terminate all
of the outstanding batches and free the shaders.

Regression since a904db3ee7 ("skip no-op colorspace transforms for
float images"), the newly added do_display_buffer_apply_no_processor
function did not handle case of both source and destination being
float images. This happens when VSE produces a float image, and
you turn on a Waveform scope.

The issue was that the code that remaps the materials for when
a slot is removed was returning when the `material_index` attribute
didn't exist instead of continuing the loop over all drawings.
This issue was present both in `BKE_grease_pencil_material_remap`
and `BKE_grease_pencil_material_index_remove`
but `BKE_grease_pencil_material_remap` forced the `material_index`
attribute to be created, which meant that the early return
was never hit.
The fix fixes both issues:
* Continue instead of return.
* Don't create the `material_index` attribute in `BKE_grease_pencil_material_remap`
if it doesn't exist.

The issue was that the strokes were not using the `POLY` type and
needed to be tagged.
This adds a function `tag_positions_changed` on the `GreasePencilDrawing`
so that the high-level python API can tag the positions if
the `point.position` attibute is written to.
