Add translation component to swipe up resistance

Browse Source 
Now recents view follows your finger all the way to the top of the
screen. Specifically, your finger tracks the bottom of the window
until resistance starts (when RecentsView is at 75% scale), then
we add translation to compensate for the slower rate of scaling
down, such that your finger slips to the top of the window by the
time it reaches the top of the screen.

Also reset this translation back to 0 in the state handlers.
