Here goes an example:
https://gist.github.com/3655316
The Z info is being lost in the conversion of `GEOSGeometry` to
`OGRGeometry`, due to the use of `GEOSGeometry.wkb` in the constructor of
`OGRGeometry`.
https://github.com/django/django/blob/master/django/contrib/gis/geos/geometry.py#L516
On a `GEOSGeometry`, only `ewkb` and `hexewkb` properties returns Z data.
But they are not understood by `OGRGeometry` constructor, but it accepts
WKT3D.
Any hints to make GEOS to OGR 3D geometries conversion work?
