If I am using CGAL::Gps_circle_segment_traits_2<Kernel>,
I can get the arc center points and
the arc orientations for any X_monotone_curve_2 with the code
shown below:

  Gen_Polygon_2::Curve_const_iterator curveIter;
  for (curveIter = poly.curves_begin();
       curveIter != poly.curves_end(); 
       curveIter++)
  {
    const X_monotone_curve_2& curve = (*curveIter);

    if (curve.is_circular())
    {
      double arc_center_x =
         CGAL::to_double( curve.supporting_circle().center().x() );
      double arc_center_y =
         CGAL::to_double( curve.supporting_circle().center().y() );
      bool clockWise =
         curve.orientation() == CGAL::CLOCKWISE
    }
  }

But how would I do the same, if I am using
CGAL::Arr_conic_traits_2<Rat_kernel, Alg_kernel, Nt_traits>?

I don't have "is_circular" or "supporting_circle" available to me
when I am using conic_traits.

I am stuck using conic_traits, since that is what CGAL::offset_polygon_2
uses.
Even though CGAL::offset_polygon_2 always returns line segments and circular
arcs.
