Original issue's description:
> [ash-md] Fades overview header in and out
>
> This change installs an additional header on top of the real window's header and animates its bounds and opacity such that it appears to take over the real header. Only once the "fake" header is opaque a mask or alpha shape is applied to the window to hide its original header after which the "fake" header becomes translucent to conform to MD overview mode spec.
>
> This creates a visually smoother transition into overview mode than before.
>
> Special care is taken to animate the "fake" header in case when the window is restored for the overview mode from the minimized state and is thus animated from the shelf item.
>
> BUG=624608, 645076
> TEST=Most changes are only really visible under a great slow-down but watching closely the files app header transform into overview mode should be much less abrupt.
