For *Agg, we use tex + dvipng and load the output as a transparent,
anti-aliased raster, caching the dvipng output in ~/.tex.cache for
efficiency.  For PS, we use tex + dvips + psfrag + latex + a patched
ps2epsi.  The latter is cumbersome, but it works.  In an ideal world,
we would simply use tex + dvips but embedding the postscript fragments
generated by dvips in arbitrary locations on the figure, but this has
proved challenging.

Having our own dvi parser would be a nice solution.  As you noted, the
format isn't too complicated, except for the font handling and the
fact that you need your own bytecode processing engine to extract the
information.  We're waiting until Robert Kern has another boring
experiment to site through for this one.
