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.
