More specifically, any window (e.g. qsb search) or AbstractFloatingView.
NavBarToHomeTouchController now implements TouchController directly instead
of AbstractStateChangeTouchController, as it not only dealing with
launcher states. This makes it easier to override intercept logic to
handle cases like not having window focus, for example.
AbstractFloatingViews can createHintCloseAnim() to play an animation
hinting that it is about to be closed by swiping up. Widgets sheets use
this to pull back similar to the all apps transition to home.
