I am trying to use postscript in markup blocks. I see snippets using such things as \translate and \scale, which I need, along with all the other plane transformation operators. Where is the documentation for these operators? I have looked everywhere to no avail. Using 2.19.16.
While we are here, I am looking for a function to draw postscript arrows. If anybody has such, I would be most appreciative. I think it would be good to have a very general and flexible arrow library in lilypond.
Thanks!
Andrew
