making a weird bonus-renderer for little prize-scenes, for players who do well enough in the campaign mode (pre-render a gbuffer offline, do user-controlled lighting/fog/sky on the device)

i'm keeping the actual scenes a secret since they're player rewards, so here's a temp tester-scene instead

a neat thing here is that the actual triangles never make it to the device, so polycount doesn't affect performance or the game's download size. in this scene, each monkey-head is 60k+ triangles!
