 18.5.3.2 Spatial Operators
 ..........................
 
 OpenGIS proposes a number of other functions that can produce
 geometries. They are designed to implement spatial operators.
 
 These functions are not implemented in MySQL.  They may appear in
 future releases.
 
 `Buffer(G,D)'
      Returns a geometry that represents all points whose distance from
      the geometry value G is less than or equal to a distance of D.
 
 `ConvexHull(G)'
      Returns a geometry that represents the convex hull of the geometry
      value G.
 
 `Difference(G1,G2)'
      Returns a geometry that represents the point set difference of the
      geometry value G1 with G2.
 
 `Intersection(G1,G2)'
      Returns a geometry that represents the point set intersection of
      the geometry values G1 with G2.
 
 `SymDifference(G1,G2)'
      Returns a geometry that represents the point set symmetric
      difference of the geometry value G1 with G2.
 
 `Union(G1,G2)'
      Returns a geometry that represents the point set union of the
      geometry values G1 and G2.
