    Delta animations don't use the Blitter. Never have, never will.

    Nor does each frame require writing to 40000 bytes. Only the bits
    that change require updating. There used to be an animation player
    that had a function key which made it draw lines all over the area
    that wasn't updated, so you could see how much of each frame was
    changed. Pretty slick, but the latest version of the program has
    dropped this function.

    They are very similar to FLI animations on PCs, which don't do
    full screen updates either.
