-- t'GI.Gtk.Objects.GestureDrag.GestureDrag' is a t'GI.Gtk.Objects.Gesture.Gesture' implementation that recognizes drag
-- operations. The drag operation itself can be tracked throught the
-- [dragBegin]("GI.Gtk.Objects.GestureDrag#g:signal:dragBegin"), [dragUpdate]("GI.Gtk.Objects.GestureDrag#g:signal:dragUpdate") and
-- [dragEnd]("GI.Gtk.Objects.GestureDrag#g:signal:dragEnd") signals, or the relevant coordinates be
-- extracted through 'GI.Gtk.Objects.GestureDrag.gestureDragGetOffset' and
-- 'GI.Gtk.Objects.GestureDrag.gestureDragGetStartPoint'.
