Hey I posted this before but it looks like it's gone now :)

I really hate to bitch about allegro, because allegro is so obviously
wonderful, but does anybody know how to keep sprites from clipping when
you rotate them? I assume this is just a limitation (?feature) of the
asm routine or algo used (I don't really know rotational algos except
the really slow kind :) and i can of course overcome this by copying to
an intermediary sprite that is big enough, or else just making all my
sprites big enough (square sprites of sqrt((w/2)*(w/2) + (h/2)*(h/2)) should
do it but that's not really important I guess). But one will slow things
down and the other wastes valuable memory.
