SteamVR composition

[avaer]

Exokit's reality tabs right now work for WebXR, and 2D browser pages (DOM-to-Texture). However, there is a lot of talk of being able to composite other apps -- especially OpenXR, SteamVR, and so on, along with Exokit's regular WebXR.

From my experiments this should be quite doable. Initial work here is courtesy of OpenComposite.

The API for this could be the same as Realty tabs (<iframe> and/or <portal>), with a src that is a local executable or existing session.

This is an issue to track these experiments. 🦄 👾 ✨

Will the src include command line args?

I don't know what the API should look like, but command-line arguments should definitely be supported. 👍
