- 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.
