SPAresfit scaling

There is no inherent requirement for SPAresfit to be equivalent among applications sharing data, because the fit values that are stored with the restored model will be scaled if the model is scaled. For normal operation (fit accuracy and speed), however, SPAresfit should be a reasonable multiple (e.g., 1000) of SPAresabs; therefore, if SPAresabs is scaled, SPAresfit should be also.
