I'm still trying to understand why a QgsFeatureRequest that's being
built with a DistanceWithin filter ends up loosing that at some point
and reached the point in which:
QgsFeatureIterator QgsPostgresFeatureSource::getFeatures( const
QgsFeatureRequest &request )
Is returning:
return QgsFeatureIterator( new QgsPostgresFeatureIterator( this, false,
request ) );
My question is: why is a QgsFeatureIterator being constructed here,
just for returning it as a value ? Why not returning a pointer
instead, to allow subclasses to return whatever derived class they want ?
