Yes, but before next friday would be good (I'll be offline for a week
and would like to use this for coding, then).

GL fog sounds just fine. I didn't know that it existed.

The only quibble is that it uses depth... but I guess it can be made to
work, it might just be a bit more difficult to program the view for it.
(Janne said that we could write a special vertex program to do the fog
and then we could do it any way we like, but it's probably not necessary
to go there.)

Will be interesting to implement this on AWT...

Ok, what should the interface for this be?
