Can someone educate me as to why this works: \markup \path #0.4 #'((moveto 0 0) (lineto -30 50) (lineto -20 80) (closepath))
but this does not: \markup \path #0.4 #'((moveto 0 0) (lineto -30 (* 2 25)) (lineto -20 80) (closepath)) The difference being I replace 50 with (* 2 25) (I'm trying to write code that will draw a box round A4 or letter paper with just a change of some scaling factors - I can work around it but it's distressing not to understand what is going on).
