Tweak the animation when the overlay comes up

Browse Source 
- Make the time a bit longer (now that we control timing in Tweener
  better it actually takes the time we specify)
- Use easeOutQuad so that we get a "soft landing" into position
- Move the anchor point of the Desktop to NorthEast to reduce jitter
