jlogandavison d00bc034b2 Bug 1180865 - Implement pinch locking in APZC. r=botond
Mechanism for restricting pinch zooming when gesture is a two
finger pan. If the pinch span is below a given threshold and the
scroll distance above a given threshold then the zoom level is
maintained to allow for smooth panning with two fingers.
