12312	MultiLineString OGRGeometry dimensions change on transform	Charlie DeTar	jbronn	"After calling ""transform"" on a 2D MultiLinestring OGRGeometry object, wkt returned by the OGRGeometry object is 3D.  

Comments the definition of OGRGeometry.transform in django/contrib/gis/gdal/geometries indicate that this may be a result of a GDAL bug (http://trac.osgeo.org/gdal/changeset/17792 ) present in GDAL versions prior to 1.7.  The transform function has a workaround that resets the OGRGeometry object's dimension property, but the resulting object still returns 3D wkt.

Attached is a failing test case."		closed	GIS	dev		fixed	gdal OGRGeometry 3D	chazen@…	Accepted	0	0	0	0	0	0
