Backup.
Backup
overhangs
Game disabled! (for libnoise-net testing)
Better chunk management, switched to SimplexNoise
Pre-height map update
new chunk rendering algorithm

the good news: chunks seem to render more quickly
the bad news: there seems to be an off by one bug that is causing a few
gaps in the surface.
pre-mesh optimization backup
Combining some verts

a new class FaceSet collects faces (in strips) and creates only four
verticies for each strip. the bad news: tiling shader now has problems.
Optimized meshes.
Tweak for x and z faces
Syncing. a lot of improvements
