The function is this :

(define (width editor)
   (image-width (text (editor-pre verwerker) 11 "black")))

As I understand your remark it doesn't use editor.  So I have to rewrite 
it so it uses the parameter editor-pre verwerker ??

Only beside. But how can I then take care that the text are displayed 
into the empty-scene.  I think you need overlay or something for that.
