Currently only supports single image frames (no animation possible).
If quality slider is set to 100 then lossless compression will be used,
otherwise lossy compression is used.
Gives about 35% reduction of filesize save when re-saving splash screens with lossless
compression.
Also saves much faster, up to 15x faster than PNG with a better compression ratio as a plus.
Note, this is currently left disabled until we have WebP libs (see T95206)

rBc1909770e7f192574ea62449dd14b4254637e604 introduced "PXR_LIB_PREFIX" for building the
dependencies, so only makes sense to use the same name in the Hydra render delegate CMake too
This patch adds a Hydra render delegate to Cycles, allowing Cycles to be used for rendering
in applications that provide a Hydra viewport. The implementation was written from scratch
against Cycles X, for integration into the Blender repository to make it possible to continue
developing it in step with the rest of Cycles. For this purpose it follows the style of the rest of
the Cycles code and can be built with a CMake option
(`WITH_CYCLES_HYDRA_RENDER_DELEGATE=1`) similar to the existing standalone version
of Cycles.
Since Hydra render delegates need to be built against the exact USD version and other
dependencies as the target application is using, this is intended to be built separate from
Blender (`WITH_BLENDER=0` CMake option) and with support for library versions different
from what Blender is using. As such the CMake build scripts for Windows had to be modified
slightly, so that the Cycles Hydra render delegate can e.g. be built with MSVC 2017 again
even though Blender requires MSVC 2019 now, and it's possible to specify custom paths to
the USD SDK etc. The codebase supports building against the latest USD release 22.03 and all
the way back to USD 20.08 (with some limitations).

Atomic operations performed by the C++ standard library might require
libatomic on platforms which do not have hardware support for those
operations.
This change makes it that such configurations are automatically detected
and -latomic is added when needed.

I noticed that there were a few variables that should not be visible per default.

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

When running `./blender/build_files/build_environment/install_deps.sh` on Ubuntu 20.04.3 LTS the following error can be seen:
```
./blender/build_files/build_environment/install_deps.sh: line 1266: [: too many arguments
```
This error results from the call:
```
check_package_version_ge_DEB $CLANG_FORMAT $CLANG_FORMAT_VERSION
```
with `CLANG_FORMAT_VERSION` being undefined.
Also as `clang-format` 13 is already released and hopefully didn't break anything `CLANG_FORMAT_VERSION_MEX` could use version bump.

Simple upgrade of OpenXR to 1.0.22, following the steps from
https://wiki.blender.org/wiki/Source/OpenXR_SDK_Dependency and
rBb69ab42982a1. No changes to Blender code were necessary, only a version
bump.
The primary motivation for this upgrade is to utilize the
`XR_HTCX_vive_tracker_interaction` extension introduced in ver. 1.0.20.
However, the latest release (1.0.22) also adds a number of potentially
useful extensions such as:
- `XR_FB_render_model`
- `XR_HTC_facial_expression`
- `XR_HTC_vive_focus3_controller_interaction`

Downgrade the Python zstandard from 0.17.0 to 0.16.0. The Python package
should be linked against the exact same version of libzstd as Blender is,
otherwise it will refuse to load from within the Blender executable.
Python zstandard 0.17.0 links to 1.5.1, whereas we need 1.5.0.
While install_deps tries to stay as close as possible from official
Blender versions of the libraries, it also strives to use as many distro
packages as possible.
OSL 1.11.16.0 is the minimal version that builds with llvm13, which is
the default llvm/clang version in e.g. Debian testing.
This reverts commit 086f191169.
There was apparently a problem using APPEND which wasn't referenced
in the commit log.
Added comment noting the reason for the discrepancy.
This was already done for APPLE & WIN32, which would
reference these libraries twice.
Now append BROTLI_LIBRARIES to FREETYPE_LIBRARIES when they're
required for linking.
No functional changes as all references to FREETYPE_LIBRARIES also
used BROTLI_LIBRARIES.
