Unattended on the desk, but it runs: loader, session, first level in both
eyes, clean quit. Also the three Frame fixes (framebuffer attachments,
engine log, refresh rate) and the JavaVM one, which touches Quest too.
How to build it, install it, where the game data goes, what the controls
are, what I changed and why, and what I've checked so far (not much on
the headset side, I haven't tried it there yet).
