Once I get the reverse lookup function working, I'll be able to convert freely
between the index of each hexagon and it's location in cube-space. At that
point, I'll be able to create landscapes using Cellular Automata.

Making a height map might not be a good idea as sharp transitions tend not to
render well in my experience, but I could use tiles and just scale them
vertically.

The only problem I foresee with the reverse lookup is that it uses a matrix
transform which I'm unsure about how to implement in PoV SDL. That is, without
implementing a matrix math macro library.
