Re: Cairo plans

I use the \postscript a lot when typesetting contemporary music e.g. 
like this:

\version "2.20.0"


wave_line = \markup {
  \with-dimensions #'(0 . 0) #'(0 . 0)
  \postscript #"0.3 setlinewidth 1 setlinecap [0 1]
 0 0 0 setrgbcolor  0.00 -3.50 moveto
 0.23 -3.71   0.47 -3.93   1.00 -4.00 curveto
 1.53 -4.07   2.36 -4.00   3.00 -3.50 curveto
 3.64 -3.00   4.11 -2.07   4.50 -1.46 curveto
 4.89 -0.84   5.22 -0.55   6.00 -0.80 curveto
 6.78 -1.05   8.03 -1.83   9.00 -1.53 curveto

16.95 -3.16  18.47 -3.82  20.00 -4.49 curveto

 \relative c''{
