 18.5.2 `Geometry' Functions
 ---------------------------
 
 Each function that belongs to this group takes a geometry value as its
 argument and returns some quantitative or qualitative property of the
 geometry. Some functions restrict their argument type. Such functions
 return `NULL' if the argument is of an incorrect geometry type.  For
 example, `Area()' returns `NULL' if the object type is neither
 `Polygon' nor `MultiPolygon'.
