    macos: avoid size/origin changes when possible
    
    If _gdk_macos_surface_move_resize() was called with various -1 parameters
    we really want to avoid changing anything even if we think we know what
    the value might be. Otherwise, we risk messing up in-flight operations that
    we have not yet been notified of yet.
    
    This improves the chances we place windows in an appropriate location as
    they don't et screwed up before window-manager placement.
