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.
