VR support

Is your feature request related to a problem? Please describe.
Godot supports OpenXR, and that proprietary simulator supports VR. You mention wanting to support more platforms. VR could be a great future target! OpenXR can be handled with the open source Monado or the proprietary SteamVR.

Describe the solution you'd like
It would be nice to be able to have full motion controller support with in-game hands, such as with my Valve Index (the only VR system "officially" supported on Linux besides the Vive)

Describe alternatives you've considered
I think if VR support were to be put on the roadmap, #100 should be done first (and the Godot 4 migration). Then you can playing with a VR headset and a controller, at least. Test for rendering issues / performance when rendering for a stereo view. If that works out, maybe motion controls later.

Currently there are very few VR games/apps specifically supporting Linux. The vast majority only target Windows, then Proton is used to translate, though it can work quite well.

I agree, having VR support for Tabletop Club would be awesome! 😁 However, I myself will not be able to add support to the game, since I do not own a VR headset with controllers (unless there is a way to simulate VR input, e.g. headset and controller position, but I am not aware of anything like this).

But that does not stop anyone that DOES have a headset from contributing! In the 0.2-rewrite branch I'm planning on making the camera controller a lot more modular so it's much easier to implement control schemes for different platforms (e.g. mobile, VR).
