Height field is used to import map shape to the game. Each pixel represents one
game tile. Its brightness is converted to the tile height.

The results of loading depned on the water height you have set in the main menu.
So you can experiment and load the same height field many times and see how the
map looks like.

Only available image format for height field is ppm - you can create those using
for example Gimp or Drops.
