fteqw/engine/client/renderer.c
Spoike c949500da8 Implement preliminary openxr plugin. inputs are still useless (can HOPEFULLY result in some prints, but nothing else), and there's no considerations for 2d things. 
Fix prediction issues with the ftenq protocol.
Fix some console image previews.
Added mod_precache cvar. set to 0 to significantly reduce memory usage in xonotic...
Prevent xonotic's random file writes from forcing full worker syncs, for faster loading.
QTV connections are now accepted only from localhost peers by default.
