Thank you very much Alexander!

@Neville: If you were speaking to me: I don't want hq2x as default scaler, but only for some games. Having set scaler=hq2x and then editing the profile via the GUI, the scaler is reset to none, so D-Fend Reloaded should definitely recognize (and offer an entry in the list of available scalers) hq2x.

Hey, great software, but why aren't hq2x and hq3x available as scalers?
