Hook up pinch-zoom and swipe gestures.
Sets UIPinchGestureRecognizer and UISwipeGestureRecognizers and
passes the result down to the sk_app::Window. To simplify detection,
swipes take precedence over pans, and pans require a single touch.
This is less flexible for the app, but in most cases I think is
what we want.
