Featured to see some more games on it.

Drawing from a chat with other mapmakers and admins, some potential improvements to the aesthetics are:

- Smooth out the 32-bit artifacts in the height-map; talk to other mappers in #zkmap to find their tools for doing this

- Add DNTS, particularly to make the rocky areas stand out more:

The wiki is a bit bare-bones so if you are looking for more guidance hit up the #zkmap channel or look at a map which has it (any recent TheMooseIsLoose map probably uses it, for instance).

- Make the rocky texture line up with the steep areas a little better on the large hills at the edge of the map

- Add some features (like snowy rocks)
