 * clicks exceed the GTK+ defaults, #GtkGestureMultiPress::stopped is emitted,
 * and the click counter is reset.
 * 
 * Callers may also restrict the area that is considered valid for a >1
 * touch/button press through gtk_gesture_multi_press_set_area(), so any
 * click happening outside that area is considered to be a first click of
 * its own.
