Experiments using midpoint displacement to generate a fractal coast.
Paints a better picture of random coast line screens.
Algorithm tweaks since values between 0 and 1 are easier to handle.
Forces coast line screens to snap together.
Snaps lines to tiles as they're generated.
Prevents the coast line from smoothing as quickly.
Simplifies iterations for coast lines.
Always provides a thin coast down the left hand side.
