    // Now look for drag gestures over label1. When one occurs,
    // tell the TransferHandler to begin a drag.
    // Exercise: modify this gesture recognition so that the drag doesn't
    // begin until the mouse has moved 4 pixels. This helps to keep
    // drags distinct from sloppy clicks. To do this, you'll need both
    // a MouseListener and a MouseMotionListener.
