// An explanation about the version hackery below: There is no real
// API to introduce custom properties to the Graph API and the
// internals have changed with Boost Version 1.51 and changes aren't
// backward compatible. To work around that we carry around two
// versions of cgal_bgl_named_params. One imitates the pre 1.51
// bgl_named_params, the newer one hooks into the API through
// inheritance and addition of the some partial specializations.
