Rune proposes that they should be ignored in the color channels and
only the alpha channel carried information about them. This would make
more sense if a) the background color is stored in the image somehow
(I like Rune's idea about 100% transparent pixels) and b) sky_sphere
is not used. I dont' really know how this will affect fog, global
media and rainbow effects. I am pretty sure it will mess the former
two up, though.
