It was using the wrong numebr of bytes per pixel. That was solved by
writing a routine to determine it.

It looks like there are some branches that add snow and first person to
the application. I'll see about merging those in.

Got it to compile using Stack.

Skybox works, but nothing else really does. I think this is a problem
with how the program is interpreting the surface pixels when
calculating the map terrain and elevation.

I think some TLC is in order.
