Turns out my previous grasp of how Minecraft does this was wrong. This seems to be the correct way. One side effect is that biome data now has less resolution. One only really notices this when looking at water, for which Minecraft does not even use the water colours for in-game, otherwise I can't really tell a big difference. Fixes #1698.

# Ok here's the big brain explanation:

|
# Minecraft's new biomes have a resolution of 4x4x4 blocks.
|
|
# This means for a 16x256x16 chunk column we get 64 times for the vertical,
|

# but they appear to either be wrong or have explained it with the eloquence of a
|

# caveman.
