No, it does not use graphics objects code in octave. I'm not very
familiar with its development. I use a simpler approach, some thing
like:

class YLine {
  double MarkerSize;

 virtual octave_value get(string prop) {
   if (prop == "markersize")
     return octave_value(MarkerSize);
  else if...
  else
     // call get of base class
 }
}

DEFFUN_DLD(get,...) {
  return object->get(prop);
}

I use gl2ps. I don't use the eps export much, but I worked fine for
the examples I tried.
