31 * ColourSchemeProperty binds names to hardwired colourschemes and tries to deal
32 * intelligently with mapping unknown names to user defined colourschemes (that
33 * exist or can be created from the string representation of the colourscheme
34 * name - either a hex RGB triplet or a named colour under java.awt.color ). The
35 * values of the colourscheme constants is important for callers of
36 * getColourName(int i), since it can be used to enumerate the set of built in
37 * colours. The FIRST_COLOUR and LAST_COLOUR symbols are provided for this.
