Comment:
I pulled your `openimageio` bump and see what you mean about `luxmark` and `luxrays`. For the moment I will defer addressing this issue because the upstream sources for `luxmark` and `luxrays` seem to have moved and it's not clear to me where the new repos are. (I see a `luxmark` repo on GitHub, but `luxrays` seems to have disappeared.)

Because `blender` is currently broken with system Python, I'm going to merge this as-is and let somebody else propose a solution for moving to a new `openimageio` in the future.
