- the pinch centre goes through the letterbox (it was off on wide phones)
- after a pinch, no drag and no tap until every finger is up (the camera
jumped when one finger lifted)
- on phones a skill is given when the finger lifts without moving, so a
pinch or a drag never gives one by accident
- a pinch left on by a lost finger-up is dropped; a third finger restarts it
- the zoom step per frame is bounded
