Class carto::ConverterSwitch< INP, OUTP, false >: This is not completely satisfactory: this class is instantiated in cases where rescaling has been requested, but the rescaling parameters are ignored silently. This may be acceptable if no explicit rescaling parameters are passed, but the constructor of this class should probably throw an exception if explicit rescaling has been requested (i.e. RescalerInfo::explicitRescale() returns true).
