[func]
get_wheel_rotation
( atom event )

Category: wxMouseEvent

Get wheel rotation, positive or negative indicates direction of rotation. Current devices all send an event when rotation is at least +/-WheelDelta, but finer resolution devices can be created in the future. Because of this you shouldn't assume that one event is equal to 1 line, but you should be able to either do partial line scrolling or wait until several events accumulate before scrolling.
