pstoedit. May not be in standard distros, but can be compiled from the
source. Here we have even used pstoedit in post-processing eps graphs
from R. It works in some cases, but, for instance, lattice graphic was
made of polygons instead of lines, and we couldn't change line widths
for horizontal lines only in panel headers.

This is what pstoedit gives for version info:

pstoedit: version 3.33 / DLL interface 108 (build Oct 17 2003 - release
build) : Copyright (C) 1993 - 2003 Wolfgang Glunz
