This node implements shortening each spline in the curve based on
either a length from the start of each spline, or a factor of the
total length of each spline, similar to the "Start & End Mapping"
panel of curve properties.
For Bezier curves, the first and last control points are adjusted
to maintain the shape of the curve, but NURB splines are currently
implicitly converted to poly splines.
The node is implemented to avoid copying where possible, so it outputs
a changed version of the input curve rather than a new one.

This will help enable development on optimizations to the perimeter
calculation here. Using C++ data structures like Array can make the
code easier to read as well.
Longer term, this can help improve integration with attributes
and possibly the new curve code (since strokes and curves are
quite similar in theory).

It turns out `BKE_mesh_copy_parameters` can be called while other
tools are running calculations, which meant that it was called at the
same time as `armature_deform_coords_impl`. Beause of that, we
shouldn't do any freeing (of the old vertex group names) there.
Since the materials are copied in the "for_eval" version anyway,
it seems to make sense to copy the vertex group name list there also.
Fixes T89877, and also the failing `deform_modifiers` test.

The new Asset Browser-based pose library is partially implemented in an
add-on. This commit enables the add-on by default, as the old pose
library was built-in and thus always enabled.
The ability to disable the add-on is there mostly for cases where
people/studios want to use their own custom pose library.
Correct cases where the X-axis of the bone (in pose space) aligns with
the pose-space Y or Z-axis. In these cases the decomposition of the
matrix fails, and a negative scale of the X-axis turns into a 180°
rotation around the Y-axis. An extra -1 scale to the X and Z axes of the
resulting matrix seems to fix things.
This is more of a first-pass refactor for the UI list template. More
improvements could be done, but that's better done separately. Main
purpose of this is to make the UI list code more manageable and ready
for the asset view template.
No functional changes for users.
* Split the huge template function into more manageable functions, with
clear names and a few structs with high coherency.
* Move runtime data management to the template code, with a free
callback called from BKE. This is UI data and should be managed at
that level.
* Replace boolean arguments with bit-flags (easily extendable and more
readable from the caller).
* Allow passing custom-data to the UI list for callbacks to access.
* Make list grip button for resizing optional.
* Put logic for generating the internal UI list identifier (stored in
.blends) into function. This is a quite important bit and a later
commit adds a related function. Good to have a clear API for this.
* Improve naming, comments, etc.
As part of further cleanups I'd like to move this to an own file.
Add function `BKE_pose_apply_action_blend()`, which blends a given
Action into current pose. The Action is evaluated at a specified frame,
and the result is applied to the armature's pose.
A blend factor can be given to blend between the current pose and the
one in the Action. Quaternions are interpolated with SLERP; it is
assumed that their FCurves are consecutively stored in the Action.
This function will be used in the upcoming new Pose Library.
New function `BKE_pose_apply_action_all_bones()`, which will be
necessary for the upcoming pose library v2.0.
This renames the function `BKE_pose_apply_action` to
`BKE_pose_apply_action_selected_bones`, to reflect that it only works on
selected bones, to contrast it to the new function.
With temporary I mean that this is not intended to be part of the
eventual asset system design. For that we are planning to have an
`AssetRepresentation` instead, see T87235. Once the `AssetList` is
implemented (see T88184), that would be the owner of the asset
representations.
However for the upcoming asset system, asset browser, asset view and
pose library commits we need some kind of asset handle to pass around.
That is what this commit introduces.
Idea is a handle to wrap the `FileDirEntry` representing the asset, and
an API to access its data (currently very small, will be extended in
further commits). So the fact that an asset is currently a file
internally is abstracted away. However: We have to expose it as file in
the Python API, because we can't return the asset-handle directly there,
for reasons explained in the code. So the active asset file is exposed
as `bpy.context.asset_file_handle`.
For the Asset Browser, this returns the active asset library of the
Asset Browser, otherwise it returns the one active in the workspace.
This gives simple access to the active asset library from UI code and
Python scripts. For example the upcoming Pose Library add-on uses this,
as well as the upcoming asset view template.
This per-workspace active asset library will be used by the asset views
later. Note that Asset Browsers have their own active asset library,
overriding the one from the workspace.
As part of this the `FileSelectAssetLibraryUID` type gets replaced by
`AssetLibraryReference` which is on the asset level now, not the
File/Asset Browser level. But some more work is needed to complete that,
which is better done in a separate commit.
This also moves the asset library from/to enum-value logic from RNA to
the editor asset level, which will later be used by the asset view.
Update vertex weights between simulation steps if they have changed.
This allows for animated vertex weights in the cloth sim.

Mainly naming (also droping the `layer_collection` in favor of just
`layer` for internal code, this is clear enough and much shorter). Add
proper parent/child identifiers, `r_` prefix for parameters also used as
return values, etc.
Also made some parameters const.
This logic is from the curve sundivide node, used to add points with
proper handles in between two existing points. However, the same logic
is used for trimming of Bezier splines, and possibly interactive point
insertion in the future, so it's helpful as a general utility.
The logic is converted to depend on a bezier spline instead of being
static. A temporary segment spline can be used for the latter use case.
The BKE_gpencil_stroke_add_points API function worked well for
creating the primitives in the add object menu, but it expected a
specific data format that doesn't make sense in a dynamic context.
As evidence of that we can see the way source data was duplicated
in the line art file just to use this API function.
This commit solves that problem in two ways:
- Clean up the line art function (this should make it faster too).
- Move/rename the function so its intended use is more clear.

This commit moves the storage of `bDeformGroup` and the active index
to `Mesh`, `Lattice`, and `bGPdata` instead of `Object`. Utility
functions are added to allow easy access to the vertex groups given
an object or an ID.
As explained in T88951, the list of vertex group names is currently
stored separately per object, even though vertex group data is stored
on the geometry. This tends to complicate code and cause bugs,
especially as geometry is created procedurally and tied less closely
to an object.
The "Copy Vertex Groups to Linked" operator is removed, since they
are stored on the geometry anyway.
This patch leaves the object-level python API for vertex groups in
place. Creating a geometry-level RNA API can be a separate step;
the changes in this commit are invasive enough as it is.
Note that opening a file saved in 3.0 in an earlier version means
the vertex groups will not be available.

In most cases the undo system was loading undo steps twice.
This was needed since some undo systems (sculpt, paint, text)
require stepping out of the current undo step.
Use a flag to limit this to the undo systems that need it.
This improves performance for other undo systems.
This gives around 1.96x speedup in edit-mesh for high-poly objects.

Rename:
- EDBM_mesh_free -> EDBM_mesh_free_data
BKE_editmesh_free -> BKE_editmesh_free_data
Since this doesn't free the edit-mesh pointer.
- BKE_editmesh_free_derivedmesh -> BKE_editmesh_free_derived_caches
Since this no longer uses derived-mesh, match naming for the related
object function BKE_object_free_derived_caches.
Also remove `do_tessellate` argument from BKE_editmesh_create,
since the caller can explicitly do this if it's needed,
with the advantage that it can be combined with normal calculation
which is faster on high-poly meshes.
During a mesh transformation in edit mode (Move, Rotate...), only part of
the batch cache needs to be updated.
This commit allows only update only the drawn batches seen in
`BKE_object_data_eval_batch_cache_deform_tag` if the new
`ID_RECALC_GEOMETRY_DEFORM` flag is used.
This new flag is used in the transforms operation for edit-mesh and
results in 1.6x overall speedup in heavy subdiv cube.

In this bug report it resulted in rendering animations stopping too early,
but this affected more areas.
After the previous cleanup commit, it becomes clear that frame and ctime
values were mixed up.
Confusingly, BKE_scene_frame_get did not match the frame number as expected by
BKE_scene_frame_set. Instead it return the value after time remapping, which
is commonly named "ctime".
* Rename BKE_scene_frame_get to BKE_scene_ctime_get
* Add a new BKE_scene_frame_get that matches BKE_scene_frame_set
* Use int/float depending if fractional frame is expected
Correctly reset `prev` and `next` pointers of action group FCurves when
separating them into distinct `ListBase`s per `bActionGroup`.
These `NULL` pointers are necessary to temporarily demarcate the start &
end of the `bActionGroup::channels` list. Having them still point to
other FCurves caused ordering issues when moving curves towards the
start/end of a group.
This commit corrects the above issue and adds versioning code to rectify
any ordering issues that may have been caused. For this purpose the
`BKE_action_groups_reconstruct()` function is rewritten to avoid relying
on the `bAction::curves` list order or `prev` link integrity.

Using the "Camera Fit Frame to Selected" operator didn't work for Grease Pencil
objects. The same issue caused grease pencil preview thumbnails to be useless
(e.g. when using "Mark Asset" on a Grease Pencil object).
Reason was that there was no logic to handle grease pencil data and its strokes
for the object display-point iterators used for the "Frame Selected" logic.

When renaming an ID somewhere in the UI after marking it as asset, it would
often get lost in the Asset Browser (scrolled out of view). It would also get
deactivated.
This patch makes sure that if an asset is active whose ID gets renamed, it is
kept active and visible. That is important for a fast, uninterrupted asset
creation workflow, where users often rename assets while working in the asset
browser.
Old code stored the new file-name to identify a file after re-reading the
file-list after the rename. For assets that doesn't work because there may be
multiple assets with the same name. Here the simple solution of just storing
the pointer to the renamed ID is chosen, rather than relying on the file-name
in this case. (Should be fine with undo, since the ID * reference is short
lived, it's not stored over possible undo steps. If it turns out to have
issues, I rather switch to a rename_id_uuid, but keep that separate from the
file->uid).

Many ui features for geometry nodes need access to information generated
during evaluation:
* Node warnings.
* Attribute search.
* Viewer node.
* Socket inspection (not in master yet).
The way we logged the required information before had some disadvantages:
* Viewer node used a completely separate system from node warnings and
attribute search.
* Most of the context of logged information is lost when e.g. the same node
group is used multiple times.
* A global lock was needed every time something is logged.
This new implementation solves these problems:
* All four mentioned ui features use the same underlying logging system.
* All context information for logged values is kept intact.
* Every thread has its own local logger. The logged informatiton is combined
in the end.

Rename the mesh circle to "Mesh Circle", mesh line to "Mesh Line",
and mesh subdivide to "Mesh Subdivide". Previously they looked exactly
the same in the search menu, and the nodes themselves had the same
label. This is a "deep" rename that also renames internal defines and
function names to match the UI.
This node is quite similar to the curve to points node, but creates
points for only the start and end of each spline. This is a separate
node because the sampling from the curve to points node don't apply,
and just for ease of use.
All attributes from the curves are copied, including the data for
instancing: tangents, normals, and the derived rotations. One simple
use case is to make round caps on curves by instancinghalves of a
sphere on each end of the splines.
