bool MgDiamond::_draw(GiGraphics& gs, const GiContext& ctx) const
{
    Point2d pts[] = { _getHandlePoint(0), _getHandlePoint(1),
        _getHandlePoint(2), _getHandlePoint(3) };
    bool ret = gs.drawPolygon(&ctx, 4, pts);
    return __super::_draw(gs, ctx) || ret;
}

{
    bool ret = false;
    if (_closed)
        ret = gs.drawPolygon(&ctx, _count, _points);
    else
