-    Run it with any 4 numeric arguments, e.g. prog 3 2 1 0.  Play with the
-    numbers to get a pleasing result, or use it for your high school algebra
-    class.

-    As should be obvious from 20 feet away, the program is a cubic plotter.
-    It plots against certain artists, splattering their cubes with graphs
-    of their cubic equations.  Those dastardly arguments are mere coefficients,
-    cogs in the wheels of the grand plot to overthrow the cubics!

-    Oh, by the way, it uses a self-contained graphtab and frame buffer.
-    It's easily modified to graph *any* 96x160 bitmap on a dumb terminal.
