Animate launcher when launching recent tasks

- Scale up adjacent recent tasks and translate away from center
  - Workspace card instead recenters in the screen
- Translate hotseat offscreen

Clicking on one of the adjacent tasks will scale it up to the
center of the screen while the center and other adjacent task
parallax to the right beneath it.
