Well, blue + yellow = green ...

Now I get it. (I think :). So eventually your software will be able to give
the correct atmospheric compensation for any altitude? This sounds like it
could be complicated, since the atmospheric density varies quite a bit over
space and time.

If descending in an anim, will we need to use multiple image map files, or
will we be able to apply the required compensation by applying a correction
function to the image_map in SDL? I suppose the multiple map method will be
much faster than doing it in SDL.
