It would be cool if we could define the markups like

(define-markup-command (bla layout properties width arg) (number? markup?)
   ((line-thickness 0.0)
    (corner-radius 0.2))

  ..
 )

where this defines that the bla command uses line-thickness and
corner-radius, and automatically extracts them from properties.   We
could then annotate the bla command automatically.


Nicolas, what do you think?
