Hmmm...  We _could_ change that by adding a fixed length table or a
linked list of transparent values found in the .geo.  This would
slow down the rendering code a bit if there were several values
listed, but it doesn't sound terribly difficult to add this feature.
This could also allow some neat stuff like removing removing water,
railroads, green areas, etc. from other maps.

If implementing this I'd probably recommend a linked list so that
the number of transparent values possible wasn't fixed.
