When the gesture starts to be recognized, gtk.gesture_pan.GesturePan will
attempt to determine as early as possible whether the sequence
is moving in the expected direction, and denying the sequence if
this does not happen.
Once a panning gesture along the expected axis is recognized,
the gtk.gesture_pan.GesturePan.pan signal will be emitted as input
events are received, containing the offset in the given axis.
gtk.gesture_pan.GesturePan is a gtk.gesture.Gesture for pan gestures.
These are drags that are locked to happen along one axis. The axis that a gtk.gesture_pan.GesturePan handles is defined at construct time, and can be changed through gtk.gesture_pan.GesturePan.setOrientation.
