Hello,

I am wondering about the output of the example on the page
http://www.boost.org/doc/libs/1_48_0/libs/graph/doc/planar_face_traversal.html

I would expect that the  vertices on the border of the
outer or unbounded face got reported in reverse order.

The vertices of inner faces are reported in clockwise order
which makes that for each edge shared by inner faces, we
traverse it once from source to target, and once from target
to source.  This does not hold for edges on the outer face.

Is this intentional, or just a documentation bug?
