The recents transition requires synchronizing the thumbnail header (the bar that animates on top of the window that is being scaled/cropped) and the application window. This change simplifies the code and removes the notion of having another animator manage the same surface, and instead ensures that the thumbnail animation has the same duration and that the thumbnail animation is deferred and cleaned up one frame after the app transition is complete.
