Configure a subregion as a video target within the window set by 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 overlaid to a specific region of that window only. After setting the new rectangle one should call
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.
