/**
 * A replacement for the AquaSeparatorUI.
 * 
 * This class provides the following workaround for an issue in Apple's
 * implementation of the Aqua Look and Feel in Java 1.4.1:
 * 

 * Menu separators are drawn using Separator.highlight and Separator.shadow
 * colors instead of a black and white line.
 * This fix affects JSeparator's.
