- * Revision History:
- * 01-Nov-2000: Allocation checks
- * 11-Jul-1997: David Hansen <dhansen@metapath.com>
- *              Changed names to vines and modified draw loop
- *              to honor batchcount so vines can be grown or plotted.
- * 10-May-1997: Compatible with xscreensaver
- * 21-Mar-1997: David Hansen <dhansen@metapath.com>
- *              Updated mode to draw complete patterns on every
- *              iteration instead of growing the vine.  Also made
- *              adjustments to randomization and changed variable
- *              names to make logic easier to follow.

- * This was modifed from a 'screen saver' that a friend and I
- * wrote on our TI-8x calculators in high school physics one day
- * Basically another geometric pattern generator, this ones claim
- * to fame is a pseudo-fractal looking vine like pattern that creates
- * nifty whorls and loops.
