Swipe gesture.
This is a Gesture implementation able to recognize swipes. After a press/move/.../move/release sequence happens, signal_swipe() will be emitted, providing the velocity and directionality of the sequence at the time it was lifted.
If the velocity is desired in intermediate points, get_velocity() can be called on eg. a Gesture::signal_update() handler.
All velocities are reported in pixels/sec units.
