| The enumeration order_selector describes options for the order of points |
| within a polygon. Polygons can be ordered either clockwise or counterclockwise. |
| The specific order of a polygon type is defined by the point_order metafunction. |
| The point_order metafunction defines a value, which is one of the values |
| enumerated in the order_selector |
