Integration with OpenComposite to use RaceLabs for OpenXR

Because it seems that direct OpenXR support isn't likely, I've been reading about the opportunity that may be provided by OpenComposite that may allow RaceLabs overlays to work with OpenXR. I've tried testing this myself, but was not able to get it working. So, I'd like to see this done, as OpenXR is much better for users of Windows Mixed Reality devices.
