Configure a subregion as a video target within the window set by
gst_video_overlay_set_window_handle(). If this is not used or not supported
the video will fill the area of the window set as the overlay to 100%.
By specifying the rectangle, the video can be overlayed to a specific region
of that window only. After setting the new rectangle one should call
gst_video_overlay_expose() to force a redraw. To unset the region pass -1 for
the @width and @height parameters.
This method is needed for non fullscreen video overlay in UI toolkits that
do not support subwindows.
