-Mapgen v3 (not doing):
-* Generate trees better
-  - Add a "trees_added" flag to sector, or something
-* How 'bout making turbulence controlled so that for a given 2d position
-  it can be completely turned off, and is usually so. This way generation
-  can be sped up a lot.
-* Add a way to generate a block partly, so that trees are not added, like
-  the chunks in v2
-* Add mud "discretely", not by guessing from the noise
-
-Mapgen v4:
-* This will be the final way.
-* Generate blocks in the same way as chunks, by copying a VoxelManipulator
-  from the map that is one block larger in all directions.

 Misc. stuff:
 ------------
 * Make an "environment metafile" to store at least time of day
