Hi,
I recently obtained the Allegro, the graphics programming library for
DJGPP.  One of the test programs that comes with it demonstrates
certain methods of sprite putting, including one called compiled
sprites.  How does this work?  According to the documentation, the
routine performs a number of immediate 'mov's, but I am unable to see
how this could make things faster.  Surely, the time for an immediate
'mov' is 1 cycle, as is the time for each mov in a 'rep movsd'?  What
is it that I'm not getting?

Thanks in advance for any explanations!
