Is it possible to create a prepared geometry object using the Python SWIG geos.ogr module? It seems that Shapely and GeoDjango both have this functionality, but I can't see any mention of it in the standard Python module source or documentation. Unless I'm missing something, this seems somewhat of an oversight.

"There's currently no access to GEOS prepared geometries in OGR. They are just internally used by OGR since GDAL 1.10 to evaluate the layer spatial filter."
