That;s an interesting idea -- I'd like to see a plug-in for that!  Pretty
easy, I guess -- maybe I'll write it (once I get a C compiler...DOH!
Anyone got a good idea for an Amiga C Compiler?)  That should be a piece
of cake to write... maybe ImageFX, too. :)

Ooo.. .problem... NOTHING in the BG could move -- if it's from an
outdoors scene, wind blowing could screw it up, as would auto-focus.  I
guess this would be trickier than I thought, since you would also likly
have to take into account different compression artifacts on each
frame...AAARGH!

<sigh>
