Future ideas:
1. Backgound with Fireworks, perhaps animated dripping letters
2. Load a .GIF file as pixmap to paste, and as background tile.
3. Add {red|green|blue}_direction and {red|green|blue}_speed options
   So one can ask to cycle only one component of the colors, or to
   cycle one component faster than another. I have manually tested
   this and it looks great. This will also enable people to do the
   color-cycling in jumps of 2 colors at a time or more, to speed up.
4. How to do separate cycle-speeds, so one could control the speed of
   color-cycling of each cycling component individually.
5. Separate code into a library of effects.
6. Reflection style text. Oren Tirosh and I are working on this one.
   Israel Levin has also volunteered to help.
7. Modify the color-gradient generation function and gradient syntax
   to allow things like: -bggrad red-blue,white,green-red which would
   give a red->blue gradient, a single white color cell, and then a
   green->red gradient.
8. Perhaps add option to do ripples in different colors.
9. Option to automatically turn off Glint after set period of time, so
   screen-blankers will not be defeated.
