43  * construct time, and can be changed through
44  * gtk_gesture_pan_set_orientation().
45  * 
46  * When the gesture starts to be recognized, #GtkGesturePan will
47  * attempt to determine as early as possible whether the sequence
48  * is moving in the expected direction, and denying the sequence if
49  * this does not happen.
50  * 
51  * Once a panning gesture along the expected axis is recognized,
52  * the #GtkGesturePan::pan signal will be emitted as input events
53  * are received, containing the offset in the given axis.
