- Add NoButtonQuickSwitchTouchController which uses
BothAxesSwipeDetector to track horizontal and vertical motion.
- Initially, we only detect swipe left to right to quick switch
(like before), but then we allow swipe up to either go to
overview (if you hold) or back home (if you don't hold).
- xDisplacement transitions non-overview components out (e.g. shelf
and workspace), and translates overview in.
- yDisplacement translates overview up and scales it down
