Example bug: 1. Swipe up to overview and let go 2. Swipe all the way to the top of the screen, past where all apps stops 3. Swipe down Before this change, you get reset in NORMAL state instead of OVERVIEW. By ensuring that getTargetState() checks the drag direction before returning a new state, we guarantee we only re-init in the case that the state is actually changing. Otherwise it's possible to change the state to one that is impossible, such as NORMAL when swiping up from ALL APPS. Change-Id: I19913dded9c94228d06289780b6400e99403f378
