When loading old blend files, versioned Actions can end up having a slot with an
'UNSPECIFIED' `target_id_type`. Assigning the slot to an ID will then set the
slot's `target_id_type` to match the type of the ID, but there was previously no
way to directly set it via Python if needed.
This PR changes the writability of `target_id_type` to match the extent of its
mutability when assigning a slot to an IDs. Which is to say, it can be set if
it's 'UNSPECIFIED', but not otherwise.
RNA doesn't have a good way to represent this, so we accomplish this with a
custom set function that simply ignores the write if the slot's `target_id_type`
isn't 'UNSPECIFIED'. This isn't ideal, but is the least-bad solution at the
moment.

In order to better interop with the broader Alembic/USD ecosystem, align
the crease values we export with what we believe is expected by native
OpenSubdiv, a 0-10 range.
On import we will translate the native OpenSubdiv range back into
Blender's 0-1 range.
To account for SubD assets produced by Blender before this change, a
compat check is put in place for both Alembic and USD to use the old
methodology when encountering such files. The compat check makes use
of the Blender version we place inside the format's metadata fields. Old
assets loaded into a new Blender will look ok. New assets loaded into an
old Blender would need to be reworked.

In ea7d07098b, the RenderReport base
class was reworked to work better with test variations.
This commit reworks the Cycles render tests file to use the new
variation system for Hardware Ray tracing and OSL tests, avoiding the
custom system put in place in previous commits.

* Disable Metal multisampling to match OpenGL.
* Block list all image half/float tests, these can all fail randomly.
* Blocklist tests failing due to issues in OpenUSD Metal implementation.
When a given render test defined in CMakeLists.txt with a `--outdir`
parameter ends with a trailing slash, the resulting global report
overwrites the specific test's report. This is because `os.path.dirname`
for a path that ends in a slash returns the same directory, for example,
`os.path.dirname('foo/bar/') => 'foo/bar'
To avoid tests being able to put the report into a weird state, this
commit normalizes the `--outdir` path to strip trailing slashes.

Emit a 'diff' for the `animdata.slot_handle` property whenever the
`.action` property is changed through a library override.
The slot handle is only meaningful within the context of the assigned
action. So when a liboverride changes the assigned action, the slot
handle should also get an override.
This is necessary even when the numerical value of the slot handle
happens to be the same in both actions, as the newly chosen slot is
different from the slot that was chosen in the library file.
This applies to direct Action assignment, NLA strips, and Action
constraints.

Add `ensure` boolean parameter to the `ActionKeyframeStrip.channels()` RNA
function. Passing `ensure=True` will ensure the channelbag for the given
action slot handle exists. This makes it more straight-forward to create
F-Curves for a slot regardless of whether there already was a channelbag
for those F-Cuves:
```python
strip = action.layers[0].strips[0]
slot = action.slots[0]
# Old:
channelbag = strip.channels(slot.handle)
if not channelbag:
channelbag = strip.channelbags.new(action_slot)
ob_loc_x = channelbag.fcurves.new('location', index=0)
# New:
channelbag = strip.channels(slot.handle, ensure=True)
ob_loc_x = channelbag.fcurves.new('location', index=0)
```

This pairs with the recently added Export test and reuses the same
.blend file. While there happens to be an instancing related rendering
test, that happens to cover Import, it's better to have a direct test

Refactored USD instancing export to support instanceable references.
With this change, it's now possible to instance object hierarchies and
geometry types other than meshes (e.g., curves, point clouds, etc.).
No longer marking mesh prims as instances in
USDGenericMeshWriter::write_mesh().
USDTransformWriter::do_write() now marks the Xform as instanceable
with a reference to the prototype's Xform when the Blender object is
an instance.
In USDAbstractWriter::mark_as_instance() the target prim is now marked
as instanceable.
Added AbstractHierarchyIterator virtual functions include_data_writers()
and include_child_writers() to allow pruning children of instanceable Xforms
in AbstractHierarchyIterator::make_writers(). These functions return true
in the base class implementation, so that the iterator behavior for Alembic
exports is unaffected. In the USDHierarchyIterator subclass, these functions
are overridden to return false if instancing is enabled and the objects are
instances.
Added virtual function AbstractHierarchyIterator::should_determine_duplication_references()
which returns true if duplication references should be resolved for children
of a given context. This function is overridden in USDHierarchyIterator to
skip processing children of instances, which is more efficient for USD export,
since children of instances are pruned during traversal for writing. For nested
instances where the original prototype is not included in the export, this also
avoids designating a duplicated object parented to an instance as "the original",
which would cause USD errors since defining a prim under an instance
proxy is not allowed.
Extended logic in `AbstractHierarchyIterator::determine_duplication_references()`
to identify prototypes.
Added new function `HierarchyContext::is_prototype()`.
Disallowing merging with parent for instances and prototypes, since
the Xforms cannot be discarded in those cases.
Extended `USDWriterAbstract::ensure_usd_material()` with special logic
to ensure materials for prototype prims are defined in the subtree of the
prototype. This helps ensure the hierarchical encapsulation requirement
for prototypes and is required by certain renderers (e.g., Houdini's Karma)
for instance materials to render.
Added a new `process_scene_graph_instances()` function to ensure
prototypes are exported as abstract prims.
Added python tests test_export_native_instancing_true and
test_export_native_instancing_false.

When an action slot does not have an ID type, and it is assigned to some

The Principled BSDF tests were previously disabled when testing
with OSL as there was a noticeable difference in noise between SVM

This PR adds new RNA properties that deprecate and replace any `sequence` property.
The old prooperties are still there and fully functional, but the description is changed
to indicate that these will be removed in the future and that the new properties should
be used instead.
| Deprecated property | Replacement property |
| --------------------------------- | ----------------------------------- |
| `context.active_sequence_strip` | `context.active_strip` |
| `context.selected_editable_sequences` | `context.selected_editable_strips` |
| `context.selected_sequences` | `context.selected_strips` |
| `context.sequences` | `context.strips` |
| `SequenceEditor.sequences` | `SequenceEditor.strips` |
| `SequenceEditor.sequences_all` | `SequenceEditor.strips_all` |
| `MetaStrip.sequences` | `MetaStrip.strips` |
Previously, rna paths for animation data on strips started with `sequence_editor.sequences`.
This PRadds versioning for the rna paths to make sure to use
the new naming scheme. This does mean that in previous versions of blender,
the animations don't show but the data is not lost (even if the file is saved in the older version).
Also do some cleanup of existing python scripts inside the source to use the
new properties.
Part of #132963.

Similar to `bpy.data.user_map`, it returns a mapping of IDs to all the
filepaths they use.
Fairly basic still, may need to be refined with more options to
control which filepaths are included etc.
Mainly intended to make handling of a production blendfile dependencies
more easy.
Also adds some basic testing of the new feature.

The name `id_root` was not descriptive, and was just a hold-over from the
equivalent (now deprecated) property on the Action itself. `target_id_type`
is more clear, reflecting that this is the type of ID the Slot is intended
to animate.
This PR also renames the corresponding `id_root_icon` to
`target_id_type_icon`.
Note that this PR updates the GLTF import/export core addon to adhere to
these name changes as well.

Cleanup and enhance our export of the USD `extent` attribute.
This does the following:
- The existing `author_extents` function now uses recently added common
code to write out the extents attribute
- A new `author_extents` overload allows the use of Blender's native
bounds for the types that support it. We now use this rather than
asking USD to recompute it for us.
- Meshes will now have their extents correctly written during animations
- Curves will now have their extents written as they were not doing so
prior to this PR
- Hair, Lights, Points, and Volumes make use of the `author_extents`
functions now
Since Curves need their extents tested, this PR also moves the test from
C++ to Python. Python tests allow for faster iteration, are more
straightforward to write, and allow usage of the USD validator.

Export
Like we do for Mesh and PointCloud, export any "velocity" attribute on
the Point domain as native USD "velocities". While testing, a few
additional blender-internal attributes were discovered being exported
which are now excluded during export.
Import
Add the cache modifier as appropriate when we detect that UsdBasisCurve
data is animated. This includes time-varying positions, widths,
velocities, and general attribute values. Before this PR, only the
positions were considered. And like Export, the native USD "velocities"
attribute is now processed.
Adds test coverage as well.

"Expected textual data output" comparison based tests for FBX,
OBJ, PLY, STL import.
- There's a tests/python/modules/io_report.py that can produce
a "fairly short text description of the scene" (meshes, objects,
curves, cameras, lights, materials, armatures, actions, images).
About each object, it lists some basic information (e.g. number
of vertices in the mesh), plus a small slice of "data" (e.g.
first few values of each mesh attribute).
- Custom import parameters, if needed, can be provided by
having a sidecar .json file next to imported file (same
basename, json extension), that would have a single json
object with custom arguments.
- Add FBX test coverage, with 46 fairly small files (total size 3.8MB)
covering various possible cases (meshes, animations, materials,
hierarchies, cameras, etc. etc.).
- Switch OBJ/PLY/STL import tests to the above machinery, remove C++
testing code.

Convert mesh objects to grease pencil, optionally preserve mesh faces as
filled shapes, and convert crease edges into strokes. Following options
are available:
- Whether to convert faces to filled strokes.
- Stroke thickness.
- Stroke offset (Using normal direction to lift strokes out of mesh
surfaces).
Note that "Crease Angle" option from legacy grease pencil is not ported
to this implementation. This option is deemed more suitable for using
geometry nodes to achieve.

When creating Action Slots for legacy Actions, always name those slots
"Legacy Slot". Before this commit, the slot was named after the ID that
is animated by the Action; this matches what Blender will do when
animating that ID from scratch.
The old versioning behaviour caused issues when dealing with legacy
Actions: if there are multiple Actions in a file (for example multiple
run cycle animations) and only one of those was assigned to the
character (the rest has a fake user), Blender would only name that one
action slot after the character. The "fake user" Actions would just be
get a slot named "Slot".
This causes issues when toggling between the different Actions, as
Blender will not automatically assign a slot when switching from the
character- named one to the "Slot" one.

This patch adds support for using integer sockets in compositor nodes.
This involves updating the Result class, node tree compiler, implicit
conversion operation, multi-function procedure operation, shader
operation, and some operations that supports multiple types.
Shader operation internally treats integers as floats, doing conversion
to and from int when reading and writing. That's because the GPUMaterial
compiler doesn't support integers. This is also the same workaround used
by the shader system. Though the GPU module are eyeing adding support
for integers, so we will update the code once they do that.
Domain realization is not yet supported for integer types, but this is
an internal limitation so far, as we do not plan to add nodes that
outputs integers soon. We are not yet sure how realization should happen
with regards to interpolation and we do not have base functions to
sample integer images, that's why I decided to delay its implementation
when it is actually needed.

This commit adds render tests for the outputs of the
texture coordinate node tested on:
- A scaled and rotated mesh
- A instanced scaled and rotated mesh
- A mesh with and without smooth shading
- A mesh with a volumetric shader
- The world background chader
And a few extra objects for specific outputs. Examples including:
- A deformed mesh for the `Generated` output
- View meshes through a reflection for view dependent outputs
- Instanced meshes using the old instancing system to test the
"from instancer" option with the UV and Generated outputs
- Additional objects with extra UV maps to ensure the correct UV map
is loaded
- And more
There are other aspects that we would ideally test
(E.g. Point clouds and hair), but these will be handled by a
separate commit and set of tests.

This rescales the whole scene by its root transform to match the same
visual size while not forcing the user to wait for scale to be applied to
each object.
This is requested by studios whose main applications / USD scenes are
in CM, because referencing and payloading scenes from disparate scales
can cause issues at resolution time.
If "Apply Unit Scale Conversion" is unchecked on import, the user now
has the ability to bring the objects in with a scale factor of 1.0, so that the
objects may be edited as if Blender's scene units matches the imported
stage's.
At export time, a "Stage Meters Per Unit" value can be chosen from a list
of common measurements, as well as setting a custom value.

The issue is that certain RNA paths cannot be generated to come
from an ID and `RNA_path_from_ID_to_property` will return no value.
We are using that function in the keyframing code to allow passing
in a pointer to a bone and a path relative to that bone.
Since there is currently no good way to find the path from the ID to an arbitrary
struct pointer (see #122427), this patch is a workaround that uses
the struct_pointer IF that happens to be an ID pointer.
Of course that still has the core limitation in place but until a
better solution is available on the RNA side this is the best we can do.

The goal of this test is to try to import some critical py scripts with the
system python of the building machine.
The main target is to ensure that these py scripts remain usable by all
buildbot machines, as some of them are using fairly outdated python
versions.
Current status:
* Scripts in `build_files` and `docs` are checked.
* Some python scripts in `build_files` were 'reverted' to be compatible
with older required python version currently (3.6).
* A few scripts are excluded from the test, mostly because they use Blender's
`bpy` module, which means they are only intended to be ran with Blender's
python anyway.
* The test is only enabled for Linux buildbots currently, as they use the
oldest Python by far.
Notes:
* Some more scripts are likely to be moved around in the future.
* Whether these tests need to be enabled on windows or macos platforms remains
an open question.
