You want to send LaTeX code to a library and getting back small EPS
files?  This is non-trivial due to the embedded fonts.  IMHO the
current dvips is not powerful enough to do that; the created eps files
are far too big because it still uses pfb without converting them to
cff.  Using PDF (either pdflatex or latex+dvipdfmx) might be a
possible alternative.

A first step could be this: Emit all text strings as a large LaTeX
document where the entries are put into \hboxes.  Then run LaTeX on
this file, writing the box dimensions into the aux file.

This would make two passes with LilyPond:

  lilypond --generate-latex-data > foo.tex
  latex foo.tex
  lilypond --use-latex-data

The --generate-latex-data option makes lilypond exit after parsing the
input file (and emitting the latex data).
I would like to see this anyway to have a chance to reliably select
non-cmr fonts for text strings in LilyPond; if you code the lilypond
part I'll provide the LaTeX part.
