chunk: handle special cases for getBlocks
...
Returning Block::AIR when chunk is not yet generated (CHUNK_STATE_GENERATED set to false) is also a way to avoid thread-unsafe concurrent
access to the IntervalMaps data structure, since CHUNK_STATE_GENERATED is set to false before
generating the Chunk and set again to true after generation is complete

write number of triangles to Chunk only when sending to GPU
...
previously the current number of vertices was stored in the chunk, and the same variable got later reused for the number of triangles. This modification increases clarity and avoid glitches when blockpicking

This way I can better watch how changes affect FPS/frame times, rather than have it capped at
60FPS/16.6ms
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
