    gdkwindow: Apply the 0x0 size bump to 1x1 before checking for the bail
    
    Otherwise, a user that calls gdk_window_resize (window, 0, 0); over and
    over won't properly fizzle out, and will queue a redraw. Clipped, but
    still. These redraws can be chatty on some platforms like Wayland, and
    there's no good reason to not avoid them.
    
    This was the case for resize grips.
