slidescreen - permute the screen image like an 8-puzzle
program takes an image, divides it into
a grid, deletes a random square of that grid, and then randomly slides
one of the neighbors of this "hole" into the hole (and repeat.)
The image that it manipulates will be grabbed from the portion of

the grabDesktopImages, grabVideoFrames,
and chooseRandomImages options in the ~/.xscreensaver
