- I make no quibbles about points one and two, but I've seen some damned im-
- pressive border animation that was only a few pixels wide. FTA's Split
- Demo was impressive, but there was another group whose name escapes me at
- the moment who did things even more impressive. Isn't the same horizontal
- positioning used for border animation as would be for palette switching?
