If you mean by 'fill', something like clearing the screen, then maybe it can
be done with the blitter, or at least one or two bit planes of the screen.
Other than that there isn't much that can else that can be done.  My best
guess is that less than 5% of the screen could be updated from a Anim file
in high res. per 1/60 of a second.  This is pretty limiting when it comes
to animation.

No one ever said any thing about the number of colors exect for you.  I think
that everyone is well aware that the amount of data is constant.
