'GI.Gtk.Objects.GestureDrag.GestureDrag' is a 'GI.Gtk.Objects.Gesture.Gesture' implementation that recognizes drag
operations. The drag operation itself can be tracked throught the
'GI.Gtk.Objects.GestureDrag.GestureDrag'::@/drag-begin/@, 'GI.Gtk.Objects.GestureDrag.GestureDrag'::@/drag-update/@ and
'GI.Gtk.Objects.GestureDrag.GestureDrag'::@/drag-end/@ signals, or the relevant coordinates be
extracted through 'GI.Gtk.Objects.GestureDrag.gestureDragGetOffset' and
'GI.Gtk.Objects.GestureDrag.gestureDragGetStartPoint'.
