* TROPICZONE_DESERT: Generated everywhere, if there is neither water nor mountains (TileHeight >= 4) in a certain distance from the tile.
* TROPICZONE_RAINFOREST: Genereated everywhere, if there is no desert in a certain distance from the tile.
* TROPICZONE_NORMAL: Everywhere else, i.e. between desert and rainforest and on sea (if you clear the water).
*
* In scenarios:
* TROPICZONE_NORMAL: Default value.
* TROPICZONE_DESERT: Placed manually.
* TROPICZONE_RAINFOREST: Placed if you plant certain rainforest-trees.
