Configure a subregion as a video target within the window set by
gstvideo.video_overlay.VideoOverlay.setWindowHandle. 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
gstvideo.video_overlay.VideoOverlay.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.
