 * It is often desirable to "split" a POLYGON with a high number of vertices into some number of smaller POLYGONs. 
 
-* From a user's perspective, some GIS processes result in very large POLYGON, for example 10,000 or 100,000 or more, vertices.  There is a case to be made that PostGIS users would benefit from standard calls to take a single POLYGON as an input,  and output some GEOMETRYCOLLECTION of POLYGON that are "equivalent", disregarding the problems inherent with the numeric precision model used.

 * For the sake of discussion. let us assume we are operating on a POLYGON with a single outer ring, that is formally valid.
