The MozMagnifyGestureUpdate event is executed periodically while processing a magnify gesture, to provide updated status information. The event's delta value represents the amount by which the gesture has moved since the MozMagnifyGestureStart or MozMagnifyGestureUpdate event.
Note: This event is sent whenever the movement of the user's fingers exceeds the number of pixels indicated by the
browser.gesture.pinch.threshold preference.General info
