BOOST::Polygon is very fine but does not support arcs, which could be useful in pcbnew.

Handling arcs in an analytic way is somewhat difficult so almost everyone simply approximate arcs with lines (just like Kicad). The `obvious' solution is using NURBS (the only ones actually representing *exactly* conical sections, Bezier and csplines are only approximating them) but I think that would be overkill...
