This patch disables compositor tests that rely on anisotropic filtering
for GPU testing. This is done until we make sure they pass universally
by not relying on hardware filtering.
Test files that rely on anisotropic filtering were moved to their own
tests to be able to disable them for GPU only.
This commit implements most features needed for simple text editing.
Active text strip can be edited in preview by pressing tab key, which
enabled text editing mode. With this mode active, outline matches text
boundary box and cursor is drawn.
Cursor can be moved with usual keys. Pressing shift starts selection.
Selection and navigation works when text is scaled or rotated. Mirrored
text is not supported in this PR. it can be done, but the text is
unreadable that way, so I kept it simple.
Multi line text is supported. Pressing return key starts new line.
Copy/paste operator uses OS copy paste buffer, so text from other apps
can be pasted.
Text is still limited to 512 characters. Text string property still
exists in side panel and is limited to single line. Individual
characters can not be styled in different way like in 3D viewport, but
the code is mostly ready for such feature.

This patch removes the references for the GPU tests and uses the CPU
references for both CPU and GPU, since they are expected to match. This
also unifies the tests scripts into a single script with an argument
for execution device.
This patch changes how transformations are realized by adjusting the
computed size of the new domain after transformation. Previously, this
was computed with the lower left corner of the domain as the origin of
transformation, while now, the center of the domain is used as the
origin. Consequently, domains shrinks/grows around their center, which
results in a more stable output as transforms are animated.
A consequence of this change is that we can no longer scale odd sized
domains to even sized domains or vice versa, since it grows/shrinks by
the same amount on both sides. Supporting this case requires further
investigation and will probably require passing down information to the
realization functions themselves.
This patch implements Font to Curves, Legacy curves to Grease Pencil and
Font to Grease Pencil conversions.
Note that Font to Grease Pencil is done by converting Font to Curves
then converting Curves to Grease Pencil. Currently we do not have
direct conversion APIs.

Contains the following changes:
- Uses new `render_layer` images in test repo
- Excludes known broken tests with Hydra Storm from USD 24.05
- packed float and packed half images show corruption
- USD export doesn't support the current light-tree .blend
- Bump the `image_colorspace` and `image_mapping` thresholds to
account for image filtering differences from OS/drivers

Both the draw manager and gpu backend used the same compilation
directive for enablement. This PR seperates them into
`WITH_GPU_DRAW_TESTS` for draw manager related tests and
`WITH_GPU_BACKEND_TESTS` for gpu backend related tests.

With the HIP-RT BVH on AMD GPUs, instances that have undergone
two sets of transformations will not render properly.
This manifests as:
- Incorrect mesh normals
- Improperly positioned, scaled, or rotated meshes
- Missing intersections
This commit adds a test for this issue to make it easier to test,
and so we can hopefully catch similar issues if we ever add more
BVH options in the future.

OptiX OSL tests were previously disabled due to a GPU driver bug
resulting in many tests failing unexpectedly.
The new driver version is now out with the fix so we can now enable
OptiX OSL testing.
This commit also updates the OptiX OSL block list with better comments,
and more tests that are known to fail and need investigating.

Until the newer Hair Curves system can fully replace particle hair, add
a small test to ensure this continues to work.
Since the hair is exported as cubic bspline curves, we can also use this
same file to test bspline import now too.

While adding tests I found that metaball export has been broken since
Blender 3.4. It would export each metaball geometry twice.
This looks to have been a side effect of a change to `object_dupli.cc`
which no longer sets the `no_draw` flag for metaballs[1]. With the flag
unset we would end up visiting this particular object twice.
Use a direct check for Metaballs now and add test coverage for the
scenario in general.

Render tests can still fail. This change will disable them until they
are in a better shape. Reduces confusion when running cycles GPU render
tests.
Known issues:
- Render in batch can take forever due to a locking issue
- Headless rendering is still in development
- Particle hair rendering is broken.

In a previous commit the Principled BSDF tests were renamed from
`principled_...` to `principled_bsdf_...`. The proposal was made to
also rename the folder these tests were in to `principled_bsdf` for the
sake of consistency. This is what this commit does.

When importing an USD, the Blender object names do not necessarily match
Prim names:
```
#usda 1.0
def Xform "xform1"
{
def Mesh "MyObject" # Will be imported as "MyObject"
}
def Xform "xform2"
{
def Mesh "MyObject" # Will be imported as "MyObject.001"
}
def Xform "xform2"
{
def Mesh "MyObject" # Will be imported as "MyObject.002"
}
```
This makes it difficult in the [USD Import Hooks]
(https://docs.blender.org/api/current/bpy.types.USDHook.html) to link a
Blender object back to its source Prim for additional processing. A
typical use cases for games is to generate UVs, create and apply a
material on the fly when importing a collision shape that does not have
a visual representation (hence no materials) based on some Prim
attributes, but that the artist needs to differenciate in Blender's
viewport.
The Import context exposes a new method `get_prim_map()` that returns a
`dict` of `prim path` / `list of Blender ID`.
For example, given the following USD scene,
```
/
|--XformThenCube [def Xform]
| `--Cube [def Cube]
|--XformThenXformCube [def Xform]
| `--XformIntermediate [def Xform]
| `--Cube [def Mesh]
|--Cube [def Cube]
`--Material [def Material]
`--Principled_BSDF [def Shader]
```
the `get_prim_map()` method will return a map as:
```python
@static_method
def on_import(import_context):
pprint(import_context.get_prim_map())
```
```json
{
"/Cube": [bpy.data.objects["Cube.002"], bpy.data.meshes["Cube.002"]],
"/XformThenCube": [bpy.data.objects["XformThenCube"]],
"/XformThenCube/Cube": [bpy.data.objects["Cube"], bpy.data.meshes["Cube"]],
"/XformThenXformCube": [bpy.data.objects["XformThenXformCube"]],
"/XformThenXformCube/XformIntermediate": [bpy.data.objects["XformIntermediate"]],
"/XformThenXformCube/XformIntermediate/Cube": [bpy.data.objects["Cube.001"], bpy.data.meshes["Cube.001"]],
"/Material": [bpy.data.materials["Material"]],
}
```

Some changes to how argparse is used in render tests:
1. Use the common approach of one dash for single-letter options (`-b`)
and two dashes for longer options (`--blender`). In this commit that
just means changing single-dashed (`-testdir`) to double-dashed
(`--testdir`).
2. Remove unnecessary `nargs` arguments. The code was telling `argparse`
to put CLI arguments into a list of one item, and then had code to
turn that one-item list into the item itself. I've just removed the
`nargs` argument altogether, as that just produces the desired
value without requiring more code.
I've also removed `nargs="+"` from the handling of the `--blender`
parameter, as that allowed for multiple occurrences of `--blender
{path}` but was silently ignoring all of those except the first.
To ensure that required arguments are present, the code now uses
`required=True` instead of `nargs`.
3. Add a `description` parameter so that `--help` shows what the
test script actually does. Also it helps people (like me) who want
to figure out which blend file is actually being opened by the
test, without making the test itself more verbose.
No functional changes, except that you now cannot add multiple
`--blender` arguments any more (the CLI invocation will fail). This wasn't
used anywhere I could find, though.

Commit 073ce98231 back in 2016 changed white balance math to do
a pow based pixel operation instead of multiplication. However
pow on negative numbers (which would happen on any HDR input) is
undefined. Until some better math is decided upon, at least ensure
the input is not negative.
During the PR that added the relevant Volume tests, the .blend file
was changed but the corresponding volume reference image was not.
This commit fixes that.
While looking into something else, I noticed that the OSL render tests
were not testing the Principled Volume tests.
This is because when running OSL tests, we skip all Principled BSDF
tests by ignoring all tests that start with `principled_`
(this was done due to noise differences between SVM and OSL).
However this had the knock on effect of skipping tests like
- `principled_absorption`
- `principled_blackbody`
- `principled_smoke`
in the volumetric test suite.
This commit fixes this issue by renaming all Principled BSDF tests to
`principled_bsdf_` and updating the block list to use this new name.

Make use of our sparse value writer in more places. Namely, when using
animated Camera or Light properties, this will prevent a needless stream
of unchanging values being written into the USD file [1]. Skeletons and
armatures benefit too but less so as typically the primary benefit only
applies to the comparatively small `scale` transform attribute, which
typically remains unchanged from frame to frame.
The newly added `set_attribute` common code can, and eventually will, be
used to reduce boilerplate elsewhere where we do the same sparse writing
dance.

While adding tests for subd import I discovered that our vertex crease
data was imported incorrectly.
This PR adds tests and fixes:
- We tried to read crease sharpness data as ints instead of floats. This
caused the import process to early-return, meaning we never load any
data at all
- Empty USD data would still cause us to create the `crease_vert`
attribute unnecessarily
- Sharpness data needs clamped to 0-1 to handle USD's SHARPNESS_INFINITE
value of 10.0
- We need to fill the `crease_vert` span with 0's since incoming USD
data may not have values set for all the verts

If a strip mask was used several times in the same frame, and it needed
to do byte->float conversion (e.g. mask is produced by a byte-color
strip, but then used in both a byte-color strip, and later on in a
float-color strip), then that byte->float mask image conversion was
introducing two inconsistencies:
- It was making mask alpha channel affect the result, which was not
happening with regular byte mask images, and
- It was converting float mask to scene linear space, which was
resulting in different image than with a byte mask.
Fix those issues by ensuring that all VSE modifiers can take either
byte or float mask as-is, without extra conversions. Previously, some
of the modifiers were done in a way where they only handled "(byte
image + byte mask) or (float image + float mask)" cases.

Rather than using a default "Anim" name when exporting armature
animations, use the animation's Action name instead. Likewise use the
UsdSkelAnimation name for the Action's name during import.
Blendshapes/shapekeys still use the default "Anim" name as there's no
action for these situations.

This adds a `unit_test_compare` function to `Curves`.
Compares the curves. Curves are the same if:
* The number of points matches.
* The number of curves matches.
* The attribute names are the same and have the same type.
* The point attribute values are within the `threshold`.
* The curve topology matches (e.g. the curve sizes are the same).
* The curve attribute values are within the `threshold`.
* The indices of the points and curves are the same (can be ignored if this should be treated as the same).
The implementation reuses the same functions as the existing
comparison function for meshes.
