This PR gives access to OpenVDB's level set filtering operations
through individual **SDF Grid** nodes.
- **Mean Curvature**: Smoothens high curvature areas more than flatter
ones.
- **Laplacian**: Approximates mean curvature flow for true SDFs at lower
computational cost.
- **Median**: Reduces noise while preserving sharp features.
- **Mean**: Fast separable averaging filter for general-purpose
smoothing with linear computational complexity.
- **Offset**: Uniform dilation/erosion operation that shifts the SDF
surface by a world-space distance.
- **Fillet**: Rounds off concave internal corners by operating only on
regions with negative principal curvature.

Cosmetic changes to "Global Transform" panel in 3D Viewport sidebar, to make it
more aligned with rest of the Blender UI.
Note that this isn't a comprehensive update, there are still many things to change
according to our discussions in #137280. This PR only includes small,
non-controversial changes so that we can land improvements in 5.0.
Bigger changes will follow in the next version(s).
List of changes:
- Close all subpanels by default.
- Move "Fix to Camera" subpanel to the bottom, so that it's not between related
"Mirror" and "Relative" subpanels.
- Follow Blender's GUI guidelines:
- Use `property_split`.
- Align related properties.
- Remove redundant label from "Relative" subpanel. The title of the subpanel
already communicates the purpose.
- Rename "Mirror Options" subpanel title to just "Mirror". It's obvious that the
panel will contain options.

This PR Updates the default colors of the Curve Handle types,
to increase readability and contrast.
Each color more different from each other to not be confusing.
Logic for the new colors:
* Purple/Dark blue is used for the `Vector` type to match the header
and sockets of Vector nodes.
* Red is used for `Auto` to show that they're locked and can't be
changed without converting the type.
* Pink/Salmon color is used for `Auto-Clamped` to be similar to `Auto`
while still being distinct.
* The remaining colors are chosen to be visually distinct from the
other colors.
This also fixes a problem caused by 1067112c11 (#145360) where
Free handle were left fully black. These black handles are extremely
hard to use with Grease Pencil objects, because Grease Pencil strokes
often are black. Because the `Free` handle selected color is also black,
handles do not show if they are selected.

Increase width in some popovers where labels would get trimmed.
This was even worst for other languages, but at least now labels don't
get ellipsis by default (English at 1.0 UI scale).
The current placement of the operators make it easy for them to blend in with
other group nodes in that menu.
This patch adds an icon to better indicate the nature of these operators, and
have separators between it and other entries of the menu.

Move the Copy Global Transform core add-on into Blender's code.
- The entire extension was one Python file. This PR basically splits
it into two, one for operators (in `bl_operators`) and the other for
UI panels. Those panels are registered in the 3D viewport's sidebar,
which were registered in `space_view3d`, but I made the decision
here to create a new file `space_view3d_sidebar`, because the main
file is getting too large and difficult to navigate. This PR puts
the global transform panel in this file. After this is merged, I
will do refactors to move the rest of the sidebar panels here as
well.
- `AutoKeying` class was moved into `bpy_extras/anim_utils.py` so that
it's reusable and also accessible from API, since it's generally
very useful. There were discussions about putting this somewhere,
but for now, I chose against it because creating a new file would
also mean PR would have to affect documentation generation, and
would complicate things. If we want to, we can probably create a new
module in the future.
- Little tweaks to labels and descriptions. Now that they exist
outside of the add-on context, and exist without the user explicitly
enabling them, they need to be more descriptive and tell users what
they actually do. They also need to conform to Blender's GUI
guidelines. Also tried organizing files a little by grouping
objects.
- Add-on properties (which included word `addon` in the name) have
been registered in C++, on `scene.tool_settings` with `anim_`
prefix.

Goal of this PR is mainly to improve flexibility and of VSE layout and
screen space efficiency.
Previously, strip properties were displayed in timeline sidebar. This
was limiting, because if you want to display as much properties as
possible, the timeline area had to be taller, but this was at the
expense of space available for preview. However there is plenty of
space in properties editor, which is mostly unused in VSE. Therefore
strip properties were moved to the properties editor.
ID pinning and path displayed in top section aren't drawn, since strip
is not an ID and can not be pinned. Since there is more space for
properties, various panels are changed to be open by default.
Mainly transform and time panels, since they are used often.
There is one minor change: The waveform display property
of sound strip was previously hidden, if timeline area had per strip
waveform display overlay set. This is no longer possible to do and the
property is always visible.

This node gives access to the integer coordinates of the the voxel that is
currently being evaluated by a field. It can be used together with e.g. the
Integer Math and Sample Grid Index node to sample neighboring voxel values.
Previously, one could only get the position of the voxel in object space.
Since sometimes field are evaluated on tiles of many voxels, just having the
voxel coordinates can be misleading. Therefore, this same node also outputs
whether it is a tile and the extent of the tile (which is 1 for normal voxels).

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 main goal is to simplify reusing this drawing code when drawing properties

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).
No functional changes.

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.
