This drops the ugly GstWaylandWindowHandle structure and is much more elegant because we can now request the display separately from the window handle. Therefore the window handle can be requested in render(), i.e. when it is really needed and we can still open the correct display for getting caps and creating the pool earlier. This change also separates setting the wl_surface from setting its size. Applications should do that by calling two functions in sequence: gst_video_overlay_set_window_handle (overlay, surface); gst_wayland_video_set_surface_size (overlay, w, h);
