\brief Enumerates the possible validity failure types for a geometry
\ingroup enum
\details The enumeration validity_failure_type enumerates the possible
reasons for which a geometry may be found as invalid by the
is_valid algorithm.
Besides the values that indicate invalidity, there is an
additional value (no_failure) that indicates validity.
