Hmm, this sounds like a good idea. I'm a total newbie when it comes to
issues like this. Unfortunately I think that performance would suffer a
great deal from additional blending?

My ultimate goal with this project is to see if it is feasible to build
something like the terrain in Combat Mission (my favourite game) in pygame
and pyopengl. After a year or so (if all works) I'd change the terrain
rendering in our game from the current 2D to this 3D engine. See a few
shots at:

Richard, I'll try your code tomorrow when I get back to the machine where
I installed pyopengl. Do you happen to have access to a png where the
alpha channel definitely works with your code? Could make it easier to
debug if I know the file is absolutely ok.
