public class LegendAxis
A NumberAxis that that runs from 0 to the number of colors in a color map. This overrides refreshTicksVertical to label the interval with the color map starting values rather than the actual numeric values in the axis. This also creates a LookupPaintScale for use with this axis so that the paint values in the color map correspond with this axis' values. This whole thing is basically a trick to allow each color map interval to be painted in an equal area, rather than have the painted area correspond to the range of the color map value. That is, if there are two intervals 0 - 10, and 10 - 50, under normal circumstances the legend will paint the 0 - 10 range in 1/5th the space of the 10 - 50 range. This legend axis insures that they each get 1/2.
