Back when I started this project, I took a look at that tile cutter
thing. The reason I went with a single image is because it has to be
updated quite a bit. It seemed like it would be too difficult to make
an image and then cut them all back up again just for a small change.
All that aside, that site that is supposed to get me started never
loaded my image. So I am pretty much at a dead end going that route.

Right now I bumped the images down to smaller PNG files, that fixed
the loading problems it seems, but now I can not see roads. Is there
anyway to overlay roads? I don't have much time to work on this, so
its kinda one of those things I would like to stay functional without
a lot of worrk.
