Remove heightmap library
- Update ReadMe
- ReadMe should also point out where the simplex implementation comes from
Round the new map generator to a planet shape
Move tile_size out of the map generator (this is a render feature, not a map feature)
Turn the new map gen into a wrapper kind of like my heightmap wrapper? (This is sorta already done in a sloppy way.)
Rebuild the multi-noise map system.
- Renormalize to Earth extremes. :D (This will probably give bad initial results and need extensive changes.)
