+\brief The polygon contains an outer ring and zero or more inner rings.
+\ingroup geometries
+\tparam Point point type
+\tparam ClockWise true for clockwise direction,
+            false for CounterClockWise direction
+\tparam Closed true for closed polygons (last point == first point),
+            false open points
+\tparam PointList container type for points,
+            for example std::vector, std::list, std::deque
+\tparam RingList container type for inner rings,
+            for example std::vector, std::list, std::deque
+\tparam PointAlloc container-allocator-type, for the points
+\tparam RingAlloc container-allocator-type, for the rings
+\note The container collecting the points in the rings can be different
+    from the container collecting the inner rings. They all default to vector.
