OpenVR update 1.10.20 -> 1.16.8, resolve deprecated crap
Interopgen OpenVR's IVROverlay to managed engine
Add VROverlayPanel - these are panels rendered in local VR space over the world, input is automatically simulated
VR.Init() in MenuDll, set VR.Enabled in Init only since it never changes
When in VR create a main menu with an VROverlayPanel, make this wide and 4k so it doesn't look ass
Basic interop of IVRInput to managed, get action origins & add VROverlay.SetTransformRelative( VRTrackedDevice )
