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.

This was an issue with creatiung the correct `reference_relations` between
input and output sockets. Those are necessary for the automatic lifetime inferencing.

When an old file that uses regular subdivision is loaded, the adapative
settings were not applied to the existing modifiers if they weren't
already using adaptive subdivision. This results in the settings
remaining at their 0 defaults which can be surprising. E.g. the
`dicing_rate` of 0 is clamped to 0.1px which is probably not intended.
Make sure to set the correct defaults in all cases now.

The issue was that the "Clear Keyframes" operator was missing call
to notify the dependency graph, and thus objects were still animated
even though the keyframes were deleted.

This is to make it easy to get the bpy paths to bpy.context.property for
example. Before this change, the easiest way was to use the clipboard
bpy.ops function. However this would make the python scripts using this
fragile as it we do not have full control of what is stored in the
system clipboard.

All looking-glass icons in Blender were left-handed.
Most OS, applications, websites, even a simple image search shows that
these icons are more often depicted right-handed.
Flip all icons that include a looking-glass.

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.

Code would early-return on failure, forgetting to free the xxhash state.
Use the `BLI_SCOPED_DEFER` util to ensure the state is always properly freed
when it gets out of scope.

## 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.

This patch swap position attribute initialization and edge construction
of boolean result. Logic is what both of these steps are last, all
future code do not build mesh topology but only maintain user
attributes. So at this point mesh already must be valid. But future
change of edge calculation (#132492) code will requer this mesh
validation to be done as part of the step. So when edges will be
calculated mesh must already be built, valid and contains position
attribute.

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.

Regression in e65524382, where what should have been essentially
(window_width / text_width) became (window_width + 1/text_width)
which is not the same at all! What the code was trying to do is
((window_width + 1) / text_width)
Most easily visible in VSE template because it defaults to
MM:SS+FRAME display format, but could be seen in other
animation related windows.

This fixes a memory leak that could occur with the
Grease Pencil Pen Tool. If the Pen Tool exited during
the initialization the `GreasePencilPenToolOperation`
object would not be deleted. The Pen Tool could end
in initialization if the `Selection Mode` was not `Points`
This problem only effected Grease Pencil, because
the `Curves` Object code properly exited.

This adds support for showing various stats of volume grids in the spreadsheet:
* Extent: Number of voxels in each direction of the bounding box of the grid.
* Voxels: Total number of active voxels in the grid. This includes all voxels
which are stored in tiles (e.g. one leaf tile contains 512 voxels).
* Leaf Voxels: Number of active voxels stored in leaf nodes. This does not
contain any voxels that are part of tiles.
* Tiles: Number of active tiles in the grid.
* Size: Estimated size of the volume grid in memory.
All these stats are cached on the volume grid now. A new `tag_tree_changed`
method has been added to invalidate the cache. Computing these stats is not
cheap (but not more than a few ms even for large grids). That mainly means that
we can't do it for socket inspection because that would cause too much overhead.
However, doing it just for the grids that are currently visible in the
spreadsheet seems fine and useful.
This also adds some general improvements to the spreadsheet:
* Support `int64_t` and `int3` columns.
* Draw ints with thousand separators.
* Support showing ints as number of bytes such as `23 MB`.

`append and reuse` is chosen as default in DNA but this enumpropertyitem
isn't added to the array when `Non data block packing` is disabled in
Developer tools (see `rna_preference_asset_libray_import_method_itemf`).
To fix this, change default in DNA to `ASSET_IMPORT_PACK`. In case of
"non packing", change import_method inside `asset_library_add()`
function. Also introduce `rna_preference_asset_libray_import_method_default`
so that "reset to default value" operator works correctly.

!146956 introduced buffer streaming and is used to improve the
performance of text rendering. However the solution didn't check the
minimum allowed offset for storage buffers.
This PR will use the correct offset. This was only visible on Qualcomm
devices as other systems don't limit this offset.

Where possible, inline sockets when the input and output are both the
image or the same value just transformed.
Even though it may make sense, do not apply this change in cases where
the image is the same when a factor is set to "0". For example the
Alpha Over node, where the "Background" matches the "Image" output if
factor is 0. Or the Mix node's "A" and "Image".
Also hide the value (usually a full white color input widget).
It makes for a more compact UI, less noise, and it matches a similar
layout in Geometry Nodes.

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.
