Implement transition for docking task in recents #4
Convert aspect scaled animations from using scaling to achieve
the translation to use translation animations directly. We set
the pivot point to the middle of the thumbnail and then manually
translate the surface.
This will allow us to use curved motion in transition when docking
a task from recents.
