This signal is emitted whenever a sequence is cancelled. This usually
happens on active touches when Event.controllerReset is called
on gesture (manually, due to grabs...), or the individual sequence
was claimed by parent widgets' controllers (see Gesture.setSequenceState).
gesture must forget everything about sequence as a reaction to this signal.
