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.

Specify that the destination curve must be initialized, and free the
existing attributes (which `CustomData_copy` doesn't do).

- 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.

Compatibility with OpenEXR 2 is preserved, since Blender releases and Linux
distribution packages can be on different versions.

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.

Issue caused by 993839ce85137ac37a978f49ae894703a39dbf6a which modified
the coarse face flags update function, but forgot the case where we have
a mapped extraction with no BMesh.

This was missing the BMesh case. Issue found while investigating T95827.

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).

Some instances might be "empty" and therefore have no dimensions.
Those should be ignored here.

The general idea here is to wrap the `CurvesGeometry` DNA struct
with a C++ class that can do most of the heavy lifting for the curve
geometry. Using a C++ class allows easier ways to group methods, easier
const correctness, and code that's more readable and faster to write.
This way, it works much more like a version of `CurveEval` that uses
more efficient attribute storage.
This commit adds the structure of some yet-to-be-implemented code,
the largest thing being mutexes and vectors meant to hold lazily
calculated evaluated positions, tangents, and normals. That part might
change slightly, but it's helpful to be able to see the direction this
commit is aiming in. In particular, the inherently single-threaded
accumulated lengths and Bezier evaluated point offsets might be cached.

Finding the greatest and/or smallest element in an array is a common
need. This commit refactors the point cloud bounds code added in
6d7dbdbb44f379682 to a more general header in blenlib.
This will allow reusing the algorithm for curves without duplicating it.

This is meant to complement the `blender::math` functions recently
added by D13791. It's sometimes desired to template an operation to work
on vector types, but also basic types like `float` and `int`. This patch
adds that ability with a new `BLI_math_base.hh` header.
The existing vector math header is changed to use the `vec_base` type
more explicitly, to allow the compiler's generic function overload resolution
to determine which implementation of each math function to use.
This is a relatively large change, but it also makes the file significantly
easier to understand by reducing the use of macros.

Fix possible overflow of Modifier UUID
The code prior this change was re-generating modifier's session UUID
prior to copying this id from the source. This approach has a higher
risk of modifiers session UUID to overflow and start colliding with
existing modifiers.
This change makes it so that modifier copy does not re-generated the
session UUID unless it is needed.

GLUT does not support offscreen contexts, which is required for the new
display driver. So we use SDL instead. Note that this requires using a
system SDL package, the Blender precompiled SDL does not include the video
subsystem.
There is currently no text display support, instead info is printed to
the terminal. This would require adding an embedded font and GLSL shaders,
or using GUI library.
Another improvement to be made is supporting OpenColorIO display transforms,
right now we assume Rec.709 scene linear and display.
All OpenGL, GLEW and SDL code was move out of core cycles and into
app/opengl. This serves as a template for apps that want to integrate
Cycles interactive rendering, with a simple OpenGLDisplayDriver example.
In general this would be adapted to the graphics API and color management
used by the app.

This does not happen with **any** image, but with images that have ID
properties.
ID properties are used to store view projection matrices (e.g. for
reprojection with `Image from View` or `Quick Edit` -- these are the
ones we are interested in), but of course they can be used for anything
else, too. The images in the file from the report have ID properties from
an Addon for example.
So the crash can reliably be reproduced with **any** image doing the
following:
```
bpy.data.images['myImage']['myIDprop'] = "foo"
```
This would lead code in `texture_paint_camera_project_exec` to think the
needed `view_data` is on the image (but in reality it was just some
other IDprop).
Solution is simple: just check `view_data` is really valid after getting
it from the IDprops.

Having this setting stored in the image space caused low level selection
logic to have to pass around the image space (which could be NULL
in some cases). Use the tool-settings instead since there doesn't seem
to be much/any advantage in having this setting per-space.

Pretty straight forward. Returns the texture dimensions count. This is
