Except when you don't. I've had cases where I've had to
convert between RGBA and BGRA (for stuffing directly into
a frame buffer on Linux, as far as I remember).

So it may be worth including some features in the standard
for describing pixel formats.

Pygame seems to have a very detailed and flexible system
for doing this, so it might be a good idea to have a
look at that.
