-This generates random cloud-like patterns. It looks quite different
-in monochrome and color. The basic 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. Then coloration is
-done based on elevation.
-
-The color selection is done by binding the elevation to either hue,
-saturation, or brightness, and assigning random values to the others.
-The ``brightness'' mode tends to yield cloudlike patterns, and the
-others tend to generate images that look like heat-maps or CAT-scans.
