public class IndexImage
This class implements an adaptive palette generator to reduce images to a specified number of colors. Ideally this would also support a better dither option than just the JDK's pattern dither. The algorithm used is the 'Median Cut Algorithm' published by Paul Heckbert in early '80s.
