      There is something seriously wrong with how ctrans is handling
      -window and -viewport options when the metafile contains a
      cell array. This can be demonstrated with the simplest of
      cell arrays. Since the original author of ctrans is no longer
      tending that code, it may be a while before we look into this.

      Unless someone else has a better idea, I think that for the time
      being you are going to have to create the desired results directly
      in your code.

      Sorry about this.
