FB_ngon_encoding (quads in glTF)

[UltraEngine]

What is the status of this extension?:
KhronosGroup/glTF#1620

Is this in use in the FBX to glTF converter? I cannot find any mention of it in this repository. We'll support it if it exists.

All I really care about is quads, so if you want to simplify this that's fine too.

I also have this I am working on. Let me know if you would like to collaborate:

I'm interested in adding this feature to our maintained version of fbx2gltf https://github.com/godotengine/FBX2glTF

Feel free to make a pr to our version.
