#GtkGestureDrag is a #GtkGesture implementation that recognizes drag
operations. The drag operation itself can be tracked throught the
#GtkGestureDrag::drag-begin, #GtkGestureDrag::drag-update and
#GtkGestureDrag::drag-end signals, or the relevant coordinates be
extracted through gtk.gesture_drag.GestureDrag.getOffset and
gtk.gesture_drag.GestureDrag.getStartPoint.
