/**
 * A lone Barguage which animates.  This unit test is meant to 
 * illustrate that a Bargauge can cope with having its 
 * orientation chanaged from horizontal to vertical or 
 * vice-versa.  This test is best run in appletviewer, so that
 * the window may be resized such that the Bargauge changes its 
 * orientation.<p>
 *
 * <em>
 * Warning:  An AWT bug causes this test to be a gluttenous 
 * consumer of resources (especially under Win95). A mouse down 
 * will halt the animation thread along with its consumption of 
 * resources.<p>
 * </em>
