Add set_render_rectangle() vmethod to the interface to better support windowless toolkits (e.g. qt graphicsview or video on canvas in general). Right now we always fill the widget to 100%. With the patch we can use a rectangular target region. Fixes #610249. API: GstXOverlay::set_render_rectangle()
