1. Tanslating contents of RecentsView instead of recentsView itself. When translating, we keep the current TaskView from moving. This allows the remoteTarget to follow an individual taskView. 2. Removing translationY in recentsView and setting the pivot instead 3. Using TaskViewSimulator for swipe handler. This allows using similar animation creation as Launcher window animation.
