       7             : mutator methods as it will break such sharing. (Sharing will be implemented
       8             : when ship types are turned into objects instead of dictionaries; this is

      13             : each mesh instance having its own set of materials but shared data, or
      14             : retarget bindings each frame. -- Ahruman
