work around and fix bugs

- Make rollo always draw.  This works around the bug somewhere that makes
  it show gray when all apps shold be closed
- Simplify the SwipeController now that we're not zooming the workspace.
- Make the readback data sane by splitting it to a different allocation.
  Now there is one allocation for each direction of data flow.
- Make AllAppsView.isVisible return the correct value.
