/**
 * This layer demonstrates interactive capabilities of OpenMap.
 * Instantiating this layer should show an icon loaded using HTTP
 * Protocol, which represents Boston, MA in USA. Above Boston it
 * should show a square that would change color when mouse is moved
 * over it in 'Gesture' mode. Also clicking once brings up a message
 * box and more than once brings up browser.
 * <P>
 * 
 * The DemoLayer has also been modified to demonstrate the first uses
 * of the OMDrawingTool. The Palette has buttons that can be used to
 * start the tool in several different ways.
 * 
 * @see com.bbn.openmap.layer.DemoLayer
 * 
 * Just added some decorated splines to test them. EL
