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

emamaker 69c44e3609 enable faceculling 
Doesn't give a massive improve in performance right now, but a nice one to have and was already made from the jme3 porting

emamaker 773b7999d4 chunkmgr: do not update same chunk multiple times 
Iterating on radius from 0 up to RENDER_DISTANCE made the algorithm check the same "sphere" multiple times

emamaker 1ccbf8b157 rudimentary frustum culling 
TODO: maybe manually extract planes and check against those

EmaMaker 8116791dcf use hilbert curve instead of flatten array 
Using valgrind heap memory tracker, this does not seem to bring any advantage on heap memory usage. To be tested more in depth

EmaMaker b724640384 chunkgen: take advantage of intervalmap structure 
brings down heap memory usage to about 67% of that using arrays (valgrind, tested on standard terrain with renderdistance at 8)
