EmaMaker 3daf994ac3 opengl: disable vsync 
This way I can better watch how changes affect FPS/frame times, rather than have it capped at

Does not introduce visible tearing.

The engine runs at about 170 FPS on my Tesla M40, and so does minecraft. It never goes past that, I think this is a
limitation of using prime offloading. Runs at 300FPS on average on the Radeon HD6850 to which I
normally offload the Tesla to

EmaMaker c547d11cd5 chunks: drop per-chunk chunkmesh 
Use a single mesher. This, on top of the previous commits, shaves off another 20MB of total RAM usage, using a total of about 120MB for a standard world (16 chunk size, 8 render distance), of which 22 in heap
