Hi,

I've put some preliminary code in CVS. use with

      lilypond -f texstr foo
      latex foo.texstr

add

        
        #(ly:load-text-dimensions (eval-string (format "(quote (~a))"
                                 (ly:gulp-file "foo.lpm"))
                         ))

to the .ly, and run.

I'm not sure that this yields the correct result, but the dimensions
seem to be used by lily.

Note: this code expects the numbers to be in points.


TODO:

        * verify results

        * add code to load the .lpm file automatically

        * add code to make lilypond-book do two passes to generate and
use .lpm
