Sorry for the dumb question, but what exactly does this give you?
A simulated 'indexed-mode' screen?  (Whenever I hear the term 'gamma,'
I think of lightness (brightness?) of the display.)

Can you, for example, have a little multicharactered sprite which has
one set of colors (say, blues and greens and yellows) and then on-the-fly
change it (without storing additional Surface bitmaps) to a different
color (say, reds and oranges)....  I'm thinking of MegaMan and SuperMarioBros
from NES :) )
