  <_description>
Cloud-like patterns.  The idea is to take four points on the edge of
the image, and assign each a random "elevation".  Then find the point
between them, and give it a value which is the average of the other
four, plus some small random offset. Coloration is done based on
elevation.

Written by Juergen Nickelsen and Jamie Zawinski; 1992.
