8393,polygon model doesn't adhere to stated Polygon concept rules.,bmccart@…,Barend Gehrels,"In the rules section for the Polygon concept it states that:[[BR]]

""If the polygons underlying ring_type is defined as clockwise, the exterior ring must have the clockwise orientation, and any interior ring must be counter clockwise. If the ring_type is defined counter clockwise, it is vice versa.""[[BR]]

However, it would appear that the supplied polygon model does not adhere to this rule, since the same type is used for inner and outer rings.  From the source: (http://svn.boost.org/svn/boost/trunk/boost/geometry/geometries/polygon.hpp) [[BR]]
