OpenXR / MetaQuest virtual keyboard

[iamthefaker]

I think the Virtual Keyboard is part of OpenXR and is documented here:
https://developers.meta.com/horizon/documentation/native/android/mobile-openxr-virtual-keyboard-integration/

Courtesy of Squarebananas:
The Silk.NET.OpenXR library has bindings for the XR_META_virtual_keyboard OpenXR extension
https://registry.khronos.org/OpenXR/specs/1.0/html/xrspec.html#XR_META_virtual_keyboard

KNI references the Silk.NET.OpenXR library, but does not expose the entire OpenXR API.

It would appear the related
Silk.NET.OpenXR bindings
https://github.com/dotnet/Silk.NET/blob/main/src/OpenXR/Silk.NET.OpenXR/Structs/VirtualKeyboardMETA.gen.cs
would need adding / passing through KNI's ConcreteXRDevice
https://github.com/kniEngine/kni/blob/main/Platforms/XR/.Oculus/ConcreteXRDevice.cs code.

Interestingly it seems the Meta Virtual Keyboard is provided at runtime as a 3d asset in glTF format, so that might add some additional challenges.
