  Snaps the vertices and segments of a geometry
  another Geometry's vertices.
  A snap distance tolerance is used to control where snapping is performed.
+  The result geometry is the input geometry with the vertices snapped.
+       If no snapping occurs then the input geometry is returned unchanged.
