    ///
    /// #### `begin`
    ///  Emitted when the gesture is recognized.
    ///
    /// This means the number of touch sequences matches

    ///
    ///
    ///
    /// #### `cancel`
    ///  Emitted whenever a sequence is cancelled.
    ///
    /// This usually happens on active touches when

    ///
    ///
    ///
    /// #### `end`
    ///  Emitted when @gesture either stopped recognizing the event
    /// sequences as something to be handled, or the number of touch
    /// sequences became higher or lower than [`n-points`][struct@crate::Gesture#n-points].
    ///
    /// Note: @sequence might not pertain to the group of sequences that
