When new display driver is given to the PathTrace ensure that there are

Add check for `NULL` `from` pointer to `BLO_main_validate_shapekeys`,
and delete these shapekeys, as they are fully invalid and impossible to
recover.

test/snow_parkour/shots/0040/0040.lighting.blend`, svn rev `1111`).
Would be nice to know how this was generated too...
This adds initial support for edit mode for the experimental new curves
object. For now we can only toggle in and out of the mode, no real
interraction is possible.
This patch also adds empty menus in edit mode. Those were added mainly
to quiet warnings as the menus are programmatically added to the edit
mode based on the object type and context.

This adds the boilerplate code that is necessary to use the tool/brush/paint
systems in the new sculpt curves mode.
Two temporary dummy tools are part of this patch. They do nothing and
only serve to test the boilerplate. When the first actual tool is added,
those dummy tools will be removed.

Previous implementation had a copy of the image user, which doesn't
contain all the data to identify changes. This patch introduces a new
struct to store the data and can be extended with other data as well
(color spaces, alpha settings).
Check for a camera-view before checking if the view is locked
to the cursor/object since the camera-view takes priority,
it reads better to check that first.
Also reuse the event offset variable.
NDOF navigation in a camera view now behaves like orthographic pan/zoom.
Note that NDOF orbiting out of the camera view has been disabled,
see code comment for details.
Resolves T93666.
For the attribute search button, the tooltip was missing
if the input socket type has attribute toggle activated.

This affected loading of EXR files with set to Linear ACES colorspace, as
well as the sky texture for in some custom OpenColorIO configurations.
Use the builtin OpenColorIO transform from ACES AP0 to XYZ D65 to fix this.
The idea is to keep `is_any_zero` in the `blender::math` namespace,
so instead of trying to be clever, just move it there and expand the
function where it was used in the class.
I noticed that there were a few variables that should not be visible per default.
It seems to me to simply be an oversight, so I went ahead and cleaned them up.

This commit should suffice to make the shader API agnostic now (given that
all users of it use the GPU API).
This makes the shaders not trigger a false positive error anymore since
the binding slots are now garanteed by the backend and not changed at
after compilation.
This also bundles all uniforms into UBOs. Making them extendable without
limitations of push constants. The generated uniforms from OCIO are not
densely packed in the UBO to avoid complexity. Another approach would be to
use GPU_uniformbuf_create_from_list but this requires converting uniforms
to GPUInputs which is too complex for what it is.

This is a bug on the Blender side, where the depsgraph does not have proper
relations for text object duplis and fails to include the required materials
in the dependency graph. But at least Cycles should not crash.
- No need for `normal_tx` array if we normalize the planes in `plane_tx`.
- No need to calculate the distance squared to a plane (with `dist_signed_squared_to_plane_v3`) if the plane is normalized. `plane_point_side_v3` gets the real distance, accurately, efficiently and also signed.
So normalize the planes of the member `CameraViewFrameData::plane_tx`.
FindOpenImageIO was updated to link to separate OpenImageIO_Util for new
versions, where it is required. For older versions, we can not link to it
because there will be duplicated symbols.

FindOpenEXR was updated to find new lib names and separate Imath. It's all
added to the list of OpenEXR include dirs and libs.
This keeps it compatible with both version 2 and 3 for now, and doesn't
require changes outside the find module.

Coarse meshes with high polycount would show as corrupted when GPU
subdivision is used with AMD cards This was caused by the OpenSubdiv
library not taking `GL_MAX_COMPUTE_WORK_GROUP_COUNT` into account when
dispatching computes. AMD drivers tend to set the limit lower than
NVidia ones (2^16 for the former, and 2^32 for the latter, at least
on my machine).
This moves the `GLComputeEvaluator` from the OpenSubdiv library into
`intern/opensubdiv` and modifies it to compute a dispatch size in a
similar way as for the draw code: we split the dispatch size into a 2
dimensional value based on `GL_MAX_COMPUTE_WORK_GROUP_COUNT` and
manually compute an index in the shader.
We could have patched the OpenSubdiv library and sent the fix upstream
(which can still be done), however, moving it to our side allows us to
better control the `GLComputeEvaluator` and in the future remove some
redundant work that it does compared to Blender (see T94644) and
probably prepare the ground for Vulkan support. As a matter of fact,
this patch also removes the OpenGL initialization that OpenSubdiv would
do here. This removal is not related to the bug fix, but necessary to not
have to copy more files/code over.

Previously, the number of action map subactions was limited to two per
action (identified by user_path0, user_path1), however for devices with
more than two user paths (e.g. Vive Tracker) it will be useful to
support a variable amount instead.
For example, a single pose action could then be used to query the
positions of all connected trackers, with each tracker having its own
subaction tracking space.
NOTE: This introduces breaking changes for the XR Python API as follows:
- XrActionMapItem: The new `user_paths` collection property
replaces the `user_path0`/`user_path1` properties.
- XrActionMapBinding: The new `component_paths` collection property
replaces the `component_path0`/`component_path1` properties.

This fixes VR pink screen issues when using the DirectX backend, caused
by `wglDXRegisterObjectNV()` failing to register the shared
OpenGL-DirectX render buffer. The issue is mainly present on AMD
graphics, however, there have been reports on NVIDIA as well.
A limited workaround for the SteamVR runtime (AMD only) was provided
in rB82ab2c167844, however this patch provides a more complete solution
that should apply to all OpenXR runtimes. For example, with this patch,
the Windows Mixed Reality runtime that exclusively uses DirectX can now
be used with AMD graphics cards.
Implementation-wise, a `GL_TEXTURE_2D` render target is used as a
fallback for the shared OpenGL-DirectX resource in the case that
registering a render buffer (`GL_RENDERBUFFER`) fails. While using a
texture render target may be less optimal than a render buffer, it
enables proper display in VR using the OpenGL/DirectX interop (tested
on AMD Vega 64).
