 * The AccessibleExtendedComponent interface should be supported by any object
 * that is rendered on the screen.  This interface provides the standard
 * mechanism for an assistive technology to determine the extended
 * graphical representation of an object.  Applications can determine
 * if an object supports the AccessibleExtendedComponent interface by first
 * obtaining its AccessibleContext
 * and then calling the
 * {@link AccessibleContext#getAccessibleComponent} method.
 * If the return value is not null and the type of the return value is
 * AccessibleExtendedComponent, the object supports this interface.
