Registration utility class to add GestureListeners to Swing components. This class manages the relationship between JComponents and the GestureListeners attached to them. It adds additional functionality to AWT Windows, without adding new API to the Window class. To add a GestureListener to a top-level Swing window, use the JRootPane of the top-level window type.
