/**
 * Four LabelCanvases, each with different insets.  The leftmost
 * LabelCanvas has standard insets (2 all around), while the
 * other three were constructed as follows:
 * <pre>
 *      insetFive.setInsets   (new Insets(5,5,5,5));
 *      insetTen.setInsets    (new Insets(10,10,10,10));
 *      insetFifteen.setInsets(new Insets(15,15,15,15));
 * </pre><p>
 *
 * LabelCanvases generate SelectionEvents, that we watch
 * for in our handleEvent() method, and print out.<p>
