`PXR_ENABLE_OSL_SUPPORT=OFF`: OpenShadingLanguage is an optional dependency of the Imaging module. However, since that module was included for its support for converting primitive shapes (sphere, cube, etc.) to geometry, OSL is not necessary. Disabling it will make it simpler to build Blender; currently only Cycles uses OSL. `PXR_ENABLE_GL_SUPPORT=OFF`: GL support on Linux also links to X11 libraries. Enabling it would break headless or Wayland-only builds. OpenGL support would be useful if someone wants to work on a Hydra viewport in Blender; when that's actually being worked on, we could patch in a new PXR_ENABLE_X11_SUPPORT option (to separate OpenGL from X11) and contribute it upstream. `PXR_BUILD_OPENIMAGEIO_PLUGIN=OFF`: It's used for loading image textures in Hydra Storm / Embree renderers which we don't use.
