Initialization

This function sets the initial seed points and initializes the map.

Expansion

Recursively expand each point.

Improvements

Other nice features that could be added:

Multiple sprites for the same terrain type. Add the sprite index to the last item of the points array in the genmap() function.
To prioritize a certain type of terrain, modify the rand function for the initial points.
Terrain transitions. It would require another pass and different sprites.
