Animates a fake TaskView in Home gesture tutorial.
The "TaskView" morphs as you drag up from the nav bar, and transforms into a "home icon" or final "TaskView" when you release your finger. If you cancel the gesture (e.g. drag back down), the view simply fades out and provides a hint to swipe straight up.
