While that's common, it's not the only one, and you have to check the bitmasks
to see which bits are red, green, and blue, especially if dealing with
big-endian vs. little-endian machines.

If it's a PseudoColor visual, which is the most common type for 8-bit,
then it's an index of an entry in the Colormap.

Other visual types are described at:
