Add sound pitch correction functionality, so that retimed sound strips
can preserve their original pitch.
This has been implemented as a GSoC 2025 project. Actual pitch
correction is done with Rubberband library, which has been already
included into Blender 5.0 library builds; and then most of the other
code has been in Audaspace, which was already updated within Blender
tree earlier.
So this PR just flips on Rubberband build option, and adds the
checkbox to VSE sound strips for pitch correction (on by default for
newly created sound strips). Pitch correction works with both
simple whole-strip retiming, as well as more complex retiming setups
where different parts of the strip use different speeds.

The operator moves selected UVs, using the num-pad for directional keys:
Modifiers control the units:
- UDIM / UV unit (NUMPAD KEY)
- Dynamic grid unit (CTRL + NUMPAD KEY)
- Pixel unit (SHIFT + NUMPAD KEY)

The main goal is to simplify reusing this drawing code when drawing properties
for group input/output nodes. This is not implemented as part of this patch
though. The UI shouldn't change, except that the old code had an incomplete
`field_socket_types` list.

Add two common building blocks for volume-grid workflows.
- **Voxelize** turns all active tiles into fully dense voxels. For fog
volumes, this will mean the "inside" sparse tiles will become
individually adjustable voxel values.
- **Prune** is the opposite action as voxelize. It can be important for
certain workflows when large regions of constant values are created.
The node can collapsed those regions into more efficient tiles or
inner nodes. There are a few modes which are each useful for
different use cases.

Explicitly set the transform of a grid.
The new transform can fail to be applied if the input transform isn't
invertible or for some extremes of scaling (0 or combinations of
negative and positive) and numerical errors with `openvdb`. If a
transform is not applied an error is raised and the `Is Valid`
returns false.

Adds four new grid operator nodes that wrap OpenVDB's differential
operators. All nodes take a grid input and output a grid, potentially
with a different data type.
New nodes:
- Grid Curl: Calculate curl of vector field (Vec3 → Vec3)
- Grid Divergence: Calculate divergence of vector field (Vec3 → Float)
- Grid Gradient: Calculate gradient of scalar field (Float → Vec3)
- Grid Laplacian: Calculate Laplacian of scalar field (Float → Float)
These operators enable vector calculus operations on volume grids for
effects like flow analysis, vortex detection, etc.

## Fix: Error in Node Wrangler UI when in Sequencer mode
Node Wrangler tried to find the current scene compositing node tree,
even when there was none. This could happen if working on a sequencer
compositing modifier.
This commit hides the Save This Image button when not in Scene
compositing mode.
## Fix: Error in Node Wrangler's Save Image op when file path is empty
If the file path is empty in Save Image operator, it returns `None`
and errors out.
This commit makes it return `{'CANCELLED'}` early in that case.
## Add webp to list of file formats for Save Viewer
## Fix: Error when Viewer Node image renamed and saved
The "Viewer Node" image that contains the current compositing node
tree's viewer data has a hardcoded name by default. However it can be
renamed by the user, which will make the Save Viewer operator fail.
This commit extracts a utility function to get the current viewer
image based on its properties, and simply saves that.
In addition, this avoids having to change the area type to an image
editor to get the current viewer node, and restoring the node editor
afterwards. This action did not restore the current node tree if the
editor was inside a node group.
## Rename "Save This Image" to "Save Viewer Image"
When calling the operator through Menu Search, it is not clear what
"Save This Image" refers to. This commit renames the operator to "Save
Viewer Image", but keeps the old name for the button label.

Minimal changes to make Rigify use the current Action API (introduced in
Blender 4.4) instead of the legacy API (removed in 5.0).
Most of the refactoring consists of:
- Find the right `Channelbag`
- Replace operations on `Action` with operations on that `Channelbag`.
I didn't manage to test all code, because some code paths are very hard
to follow, and others seem to only be available for legacy rigs.

Convert the code in `scripts/modules/animsys_refactor.py` from the
legacy Actions API to the current API.
The code was made for very old rigs (2.70 and older, last updated for
Caminandes in 2014). The updated code seems to work on a Caminandes test
file, and produces the same logging on the terminal as in Blender 4.3
(before slotted Actions).

The general idea is to order all menus as:
```
Common categories
(e.g. Input/output)
---
Specific categories
---
Assets
--
Common categories
(e.g. Group/Layout)
```
## Changes:
### Compositor
- Removed Color/Mix submenu
- Moved Vector to Utilities
- New Category: "Creative". This is where most new assets will fit in.
- Moved to Creative:
- Kuwahara
- Pixelate
- Posterize
### Geo Nodes
- Moved 'Vector' to 'Utilities'
- Moved 'Attribute' before 'Geometry'
- Moved 'Material' to 'Geometry'
- Moved 'Color' to top level, grouped with Utilities
### Shader
- Moved 'Vector' to 'Utilities'
- Deleted 'Converter'
- New 'Displacement' menu
- Grouped 'Color' with Utilities (remains top level)

Use the current Action API (i.e. move away from the to-be-deleted-in-5.0
one) to import and export F-Curves from/to FBX files.
There is a slight difference in functionality for the exporter, in the
selection of which Actions to export for the "All Actions" option. This
is just a minimal change to ensure the legacy API is no longer used.
Old: `action.fcurves` was iterated, and if all FCurves could resolve to
existing properties, the Action was exported. This would only work
reliably for single-slotted Actions, due to the use of the deprecated
`action.fcurves` property.
New: the above check is done for each Channelbag in the Action. The
first Channelbag that match the above check is exported. This does _not_
export all suitable channelbags; it merely improves on the old behaviour
slightly.

This adds versioning code that replaces any timeline with a
dopesheet where the footer is shown, AND it removes the
timeline from the menu options.
If the area is too small to show both, the footer and the
header then only the footer is shown.
This assumes that users created the small timeline
just for the playback controls
Any uses of `SACTCONT_TIMELINE` (except for versioning) have been removed.

The purpose of this node is to create a grid with new voxel values on
the same grid topology as an existing grid. The new values are the
result of field evaluation. Multiple grids can be created at the same
time, so that intermediate results used for multiple grids can be
efficiently reused during evaluation. This is more efficient than the
"Volume Cube" node, for instance, because the output grid shares the
sparseness of the input topology grid.

Currently, attempting to split connected strips that are not both
selected means that only one of the strips are affected. This violates
the "connected" principle, so this PR makes the split operator propagate
the split to connected strips by default. Holding alt returns old
behavior (ignores connections), similar to selection logic.

Remove the operators to convert a legacy pose library (from Blender 2.93
and older) to the current system (introduced in Blender 3.0).
The removal is mostly because the pose markers do not play well with
slotted Actions. The conversion code was never updated for those, and by
now it's easier to remove them than to update the code to the current
data model.
Technically it was still possible to create a legacy pose library (an
Action with pose markers) in current versions of Blender, and then use
this operator to convert that to a modern pose library. I don't know of
anybody doing that, though.

The changes:
1. Add `group_name` to the `channelbag.fcurves.new()` and
`action.fcurve_ensure_for_datablock()` RNA functions.
2. Add `anim_utils.action_ensure_channelbag_for_slot(action, slot)`.
3. Add `channelbag.fcurves.ensure()` RNA function.
This makes it possible to replace this legacy code:
```py
fcurve = action.fcurves.new("location", index=2, action_group="Name")
```
with this code:
```py
channelbag = action_ensure_channelbag_for_slot(action, action_slot)
fcurve = channelbag.fcurves.new("location", index=2, group_name="Name")
```
or replace this legacy code:
```py
fcurve = action.fcurves.find("location", index=2, action_group="Name")
if not fcurve:
fcurve = action.fcurves.new("location", index=2, action_group="Name")
```
with this code:
```py
channelbag = action_ensure_channelbag_for_slot(action, action_slot)
fcurve = channelbag.fcurves.ensure("location", index=2, group_name="Name")
```
Note that the parameter name is different (`action_group` became
`group_name`). This clarifies that this is the name of the group, and
not a reference to the group itself.

The issue was that the used operator just took the active node into account.
However, clicking in empty space does not make the active node inactive.
Therefore, sometimes clicking on empty space would sometimes remove enter the
last selected group node. Furthermore, double clicking on other nodes may also
trigger exiting the current group.
This is fixed by introducing a new operator that explicitly checks what node is
hovered.

Node wrangler has a "delete unused nodes" operator that will delete
nodes that do not contribute to the output of the node network.
Warning nodes, don't contribute to the output of the geometry nodes,
but it does output information to the Geometry nodes UI. So warning
nodes should still be considered nodes that contribute to the output.
This commit adds warning nodes to the list of nodes that contribute
to the output to avoid them being deleted by the "delete unused nodes"
operator.

The Node Wrangler addon has a _Reset Nodes_ operator that can remove the input
node of a node zone. This crashes in reference set updates because the code
expects valid input/output node pairs in each zone.
The fix is two-fold:
1. Finding zones for the runtime now returns an empty result to ensure no
invalid node pointers are being accessed. This should not happen in practice,
all operators should make sure zone relationships are not broken.
2. The node wrangler addon is updated to ignore all zone types, including the
newer repeat, closure, and for-each-element zones. The type filtering was
outdated and now uses the `bl_idname` consistently.
