This method changes the ring orientation of all Polygons in a GeometryCollection but doesn't remove or change any Points or LineStrings in the given collection.
If you pass a GeometryCollection to this method, each instance in the collection reorients as a result, but the whole collection doesn't reorient.
DECLARE @R GEOGRAPHY = GEOGRAPHY::Parse('Polygon((-10 -10, -10 10, 10 10, 10 -10, -10 -10))'); SELECT @R.ReorientObject().STAsText(); --Result: POLYGON ((10 10, -10 10, -10 -10, 10 -10, 10 10))
