The GIS function ST_Simplify takes ad input a geometry and a double. It
applies the Ramer-Douglas-Peucker algorithm on the geometry and returns
the resulting geometry. The tests have been cherry-picked from the MySQL
implementation of this function to grant compatibility among the two
implementations.
