#GtkGestureLongPress is a #GtkGesture implementation able to recognize
long presses, triggering the #GtkGestureLongPress::pressed after the
timeout is exceeded.
If the touchpoint is lifted before the timeout passes, or if it drifts
too far of the initial press point, the #GtkGestureLongPress::cancelled
signal will be emitted.
