Rename QNativeGestureEvent::deltas() to delta(); clarify docs
In QPanGesture this is called delta().
OTOH we have QWheelEvent::pixelDeltas().
Delta is a vector, and there's only one (with two components).
Native gestures hold incremental values: e.g. the pinch gesture event
provides an incremental amount of either zooming or rotation (so most
events have QNativeGestureEvent::value() very close to 0).
It's the same with the pan gesture's delta().
Add better docs for swipe and pan gestures.
