Fix recents <-> full screen animations in landscape.

Somewhere along the way we lost the accounting for system decorations
when calculating the crop of the application window during the
recents to/from full screen app transition. This is necessary,
otherwise the animation starts/ends with a black navigation bar and
there is no sense of continuity with the recents thumbnail.
