\brief Enumerates options for defining if polygons are open or closed
\ingroup enum
\details The enumeration closure_selector describes options for if a polygon is
    open or closed. In a closed polygon the very first point (per ring) should
    be equal to the very last point.
    The specific closing property of a polygon type is defined by the closure
    metafunction. The closure metafunction defines a value, which is one of the
    values enumerated in the closure_selector
