This is not the only problem with pixel fog. I have only checked this in
3.0, not 3.1b3, but it may be related and thus of some use:
On at least one system I tried this on (64bit Irix 6.5), with GL_NICEST as
the fog hint, the colors were also wrong. This was in a 24-bit TrueColor
visual.
black mapped to blue (0 0 0) => (0 0 1)
red mapped to cyan (1 0 0) => (0 1 1)
green mapped to magenta (0 1 0) => (1 0 1)
blue mapped to blue (0 0 1) => (0 0 1)
Since this was an RGBA visual, I image the byte order was probably getting
swapped.
