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.
