    waylandsink: stack the video subsurface into another subsurface that covers
the whole render rectangle

    The main reason behind this is that when the video caps change and the
video
    subsurface needs to resize and change position, the
wl_subsurface.set_position
    call needs a commit in its parent in order to take effect. Previously,
    the parent was the application's surface, over which there is no control.
    Now, the parent is inside the sink, so we can commit it and change size
smoothly.

    As a side effect, this also allows the sink to draw its black borders on
    its own, without the need for the application to do that. And another side
    effect is that this can now allow resizing the sink when it is in top-level
    mode and have it respect the aspect ratio.
