Every model of the Visibility_2 concept must provide two overloaded member functions, called `Visibility_2::visibility_region()` functions, that compute the visibility region of \f$ p \f$ in a bounded polygonal face \f$ f \f$: one is for the case where \f$ p \f$ is in the interior of \f$ f \f$; the other one is for the case where \f$ p \f$ is on the boundary of \f$ f \f$.

The following example shows how to obtain the regularized and non-regularized visibility regions.
