with structuredAttrs lists will be bash arrays which cannot be exported
which will be a issue with some patches and some wrappers like cc-wrapper
this makes it clearer that NIX_CFLAGS_COMPILE must be a string as lists
in env cause a eval failure
keep a couple of packages "using" openimageio_1 - both are broken
anyway, but as such we have no evidence that they work with 2.x.
all are liable to get removed in the near future anyway.
Enables the WebP image format support in Blender. It has been [supported](https://developer.blender.org/rB4fd0a69d7ba) since Blender 3.2 but was disabled due to libwebp missing from the build inputs.

There are many different versions of the `cudatoolkit` and related
cuda packages, and it can be tricky to ensure they remain compatible.
- `cudaPackages` is now a package set with `cudatoolkit`, `cudnn`, `cutensor`, `nccl`, as well as `cudatoolkit` split into smaller packages ("redist");
- expressions should now use `cudaPackages` as parameter instead of the individual cuda packages;
- `makeScope` is now used, so it is possible to use `.overrideScope'` to set e.g. a different `cudnn` version;
- `release-cuda.nix` is introduced to easily evaluate cuda packages using hydra.
blender 3.1 now requires python 3.10 and zstd to build. also pin
cudatoolkit to 11 and optix to 7.3 as requested by the blender build
instructions for 3.1
python is currently pointing to the python38, so this patches the
required version to match python version that is provided to the
expression. The m prefix denotes the pymalloc ABI for python 3.7 and
older, but is not provided starting python 3.8.
