Inspiration from Blender's OpenXR implementation

[NumesSanguis]

GitHub notified me of the update to the README of pyopenvr. Since you're switching to OpenXR and I just happen to know that Blender (a Python-based free and open source 3D creation suite) has been working on integrating it as well. You might be able to reuse some code from that project:
https://wiki.blender.org/wiki/Source/Interface/XR

I don't know the current state of that project, but thought to just leave this pointer here ^-^

Thanks for the tip! This is especially interesting to me since I am a long time Blenderer.
