+ Crop the palette so that it looks a bit more like metaballs.
  * AUTHORS THANKS:
    + Credited Jylam and Jan Hubicka.

+ Huge coding style overhaul.
    + Display 5 metaballs instead of 3.
    + Generate the palette instead of having a static one.
    + Use a 256x256 back buffer for more smoothness.

+ Metaballs demo program from Jean-Yves Lamoureux <jylam@lnxscene.org>.
