Right. What I think he's saying is that the user would set a callback
like you have described, but that function would be called from the
resize_window/resize_screen function. So, for example, it'd work like this:

int resize_screen(int w, int h)
{
  if(_window_resize_callback && gfx_driver && gfx_driver->resize_window)
  {
    if(gfx_driver->resise_window(w, h))
    {
      _window_resize_callback(w, h);
      return TRUE;
    }
  }
  return FALSE;
}

Then when the message handler function receives a resize message, it
calls the resize_screen function.
