Servo should support using OpenXR on Linux via Monado

[RangerMauve]

There's a growing community of OpenXR projects building on Linux around monado.

It would be nice if Servo supported this so that people could easily experiment with WebXR on Linux based systems compared to the closed source Windows/Mac/Oculus environments.

I agree this would be a good improvement. It will require some way of indicating the desired backend (D3D or GL) when creating the OpenXrDiscovery struct, and restructuring some of the code like this to support non-windows platforms.

For what it's worth, https://github.com/Ralith/openxrs supports Monado and it looks like the author of that lib is actively in the Monado Discord.

Currently working on this right now, any advice?

What kind of advice are you looking for?

really just any ideas, tips, tricks... you know this codebase better than I do, I just know Rust and OpenXR and OpenXRs...

I think it generally requires the following:

• make the openxr backend of the webxr crate support linux (see all uses of d3d in https://github.com/servo/webxr/blob/master/webxr/openxr/mod.rs)
• integrate the openxr backend into linux builds in https://github.com/servo/servo/blob/aa427dd4122359901b5d7b613bc54f64fdb94364/ports/libsimpleservo/api/src/lib.rs#L827-L897

Okay just as I thought then, thanks so much for confirming that those are the 2 spots to focus on!

Also if you need some examples of OpenXR usage on real browsers for inspiration you can check Chromium's implementation and also Wolvic's implementation
