The recent improvements in Monado like out of process compositing and multi-layer rendering released with v0.2 prepared the requirements to implement OpenXR's XR_EXTX_overlay extension.

By implementing this extension we are exposing Monado's multi-application support, which was recently merged to master.

In the video below you can see Monado compositing the rendering of Blender's VR view and the xrgears demo displaying a XrCompositionLayerProjection as overlay. The demo also showcases Monado's ability to deal with multiple graphics APIs as Blender uses OpenGL and xrgears Vulkan to submit its frames.

To enable the extension in xrgears only this small change was required, which enables the XR_EXTX_overlay extension and passes the XrSessionCreateInfoOverlayEXTX struct to the graphics bindings `next` field.

The branch of xrgears running as an overlay can be found here.

Thank you Pluto VR for making this work possible!
