Re: Formulas in diagrams exported to LaTeX... Last known working version?

[Andrew Wagner <drewm1980 gmail com>]

I tinkered around a bit.  I was able to typeset at least some formulas
by modifying the pgf export plugin.  I'm sure this will still have
formula alignment issues, but it at least works for characters and
small expressions.  Here is a diff:
