Agreed, but Frank was just pointing out that in the overload where the 
pixelSpace and lineSpace args are not specified, it's better to pass 
those parameters on to the underlying GDAL function as zeros, rather 
than the values I suggested in my e-mail. The zeros tell GDAL to assume 
default values for those parameters - which are the same as the ones I 
explcitly suggested.
