/** <b><i>NOTE: This class is used by TabSplitter and is not intended to be used 
 *  directly.  It has several methods that are specifically related to TabSplitter.</i></b>
 *
 *  TabLabelPanel is used to provide a nice title button for
 *  a component that used to be its own tab in a TabSplitter
 *  but is now part of a panel with a SplitterLayout.
