The GDAL and OGR drivers are now basically the same but separate ones in
Swig bindings, maybe it has something to do with this oddity.
When I open GDAL driver "Memory", it does not advertise capability
DCAP_RASTER and CreateDataset silently fails.
When I open GDAL driver "MEM", it advertises capability DCAP_RASTER and
CreateDataset returns a valid object.
When I open MEM driver and then Memory driver, both behave similarly.
Both MEM and Memory are listed as GDAL drivers.
Cheers,
