The double quaternion blending method in addition to the deformation
matrix of each bone requires their rest matrices. For ordinary bones
this literally should use the bone rest matrix without any ambiguity.
However, it was also using the bone rest matrix for all of its
B-Bone segments, which is incorrect and causes strange deformation
in some cases involving extreme non-uniform scale, especially
at boundaries between different B-Bones. There is also a similar
known issue that happens with scale at bending joints, and this
fix reduces the distortion when both bones are B-Bones.
This changes both the Armature modifier and the Armature constraint
to use the actual segment rest matrices. Unlike bones, these can have
scale even in rest pose, so normalization is required.

Average selected tracks into the new one. This can be used to improve
stability of tracking on blurry or non-very-sharp feature shapes.
Averaging happens for all position, pattern corners and search area.
Disabled markers do not take effect on averaging. Keyframed flag is
copied from source.
Gaps in the source tracks will be linearly interpolated, to reduce
result track jump. Note that this only applies to gaps "inbetween".
This means that if an input track doesn't have markers in the
beginning/end of it, there is nothing to interpolate with and the
result track will jump.
Available from the Track panel, under the Merge category.

There are two main things.
First, remove the marker index caching. Thins makes it possible to
safely use function from a threaded environment.
Second, replace linear search with binary search, which speeds up
random lookup.
There is no measurable difference in the stabilization which had a
comment about caching nature of track lookup. The random lookup
complexity changed from O(N) to O(log N). In practice this also
unlikely to be measurable, but thread-safety worth it.
overrides
Editing bone groups is not supported on proxies/overrides [changes a re
lost on file reload], need to do proper polling (and also prevent this
from rna) for:
- adding bone groups
- removing bone groups
- renaming bone groups
- setting bone groups colors
Previously, this was hinted at by setting the layout inactive, with
preoper polls, this is now not needed anymore.
note: Selection of bone groups actually makes sense here and is
supported, so this is not prevented in this patch, but UI wise this is
not nice in the override case, because one cannot set an active_index
(aka select) in the UI list.

Individual projection is a different branch of snap and always projects
the transformed elements on the surface of objects.
Perhaps this option should be limited to the Move mode due to similarity.
But in order not to change the current behavior too much, this commit only
disables this option in modes not affected by snap.
Outliner display under 'Animation' > 'NLA Tracks' was not updating in
the following cases:
- adding strips
- removing strips
- duplicating strips (possibly to different track)
- swapping strips
- reordering tracks
- changing strip order by translating
- translating strips between tracks
- renaming tracks
In the case of deleting strips/tracks, this was also resulting in a use-
after-free error in Outliner drawing code (this was reported specifically
in T84586).
Most of these operators already sent a ND_NLA|NA_EDITED notifier, but the
Outliner is not listening to these. Listening to NA_EDITED is also not
what we want since this also happens a lot in cases irrelevant to the
Outliner. Now be a bit more specific and send ND_NLA|NA_ADDED / ND_NLA|
NA_REMOVED or a new ND_NLA_ORDER (to distinguish from NA_EDITED
'only' - where a redraw is not neccessary) and listen to these from the
Outliner.
(note: places that were listening to ND_NLA|NA_EDITED before are also
listening to NA_ADDED or NA_REMOVED, so changing NA_EDITED should not be
a problem here)
(note 2: for cases like swapping tracks/strips order, NA_ADDED or
NA_REMOVED does not make sense, neither can we use NA_EDITED [since we
dont want to listen to this], so in this case an additional ND_NLA_ORDER
is now sent)
(note 3: in nla transform code, this is now always sent on confirm. There
are cases were the notifier would not be needed, but checking exactly all
cases were it actually would be needed seems overkill [history of D10073
has example code to check if strips moved between tracks])

The WORLD_UPDATE operation (needed to free the gpu material) was already
defined in DepsgraphNodeBuilder::build_world, but corresponding relation
was only set up for changes in the nodetree, not for changes in the
world/material itself in DepsgraphRelationBuilder::build_world.
Direct changes to these surface properties in the UI were updating
properly through RNA property update callbacks, but these are not called
from the animation system.
So now add these relations in the depsgraph.
Not 100% sure this is the right place for this (since e.g. eevee engine
seems to handle e.g. animated light paramters just fine through
EEVEE_cache_populate / eevee_light_setup, but properly freeing gpu
materials wont happen for worlds in e.g eevee_id_world_update and also
not for materials)

The target stroke bounding box was not checked properly and when using layer transform the error was noticeable, but really the error was before the layer transform commit.
This implements the node tree update function, which is needed so that the
reroutes get updated to the correct type. It is based on the same code in
the shader and compositor node trees.

When using grease pencil for drawing Storyboards, it's very common to require a transform of the layers. This transform can be done using the offset modifier, but in some cases, the scene requires a lot of modifiers and makes the file hard to work.
This new feature adds a transforms Location, Rotation and Scale at Layer level, and allows to transform the layer without using a modifier, keeping the scene more clean.
{F9480695}
This feature was suggested by @pepeland after receiving feedback from several artists.
Also, done some code cleanup and rename some functions to get a better naming.

The issue was that the mesh shared its vertex weights with the
original mesh (to reduce memory consumption). The solution is
to make a local copy of the vertex weights in this case.
This adds a "Snap to" option that allows using all the scenes snap
settings which includes incremental & absolute grid snapping options.
This is optional because always following scene snapping would not
snap to geometry by default (which seems to be the most useful default).
