Regarding the StateVariable filter, I guess it will be a good idea to keep old code working as before. Arguably, the center frequency shift is a bug, but there may well be existing code where the frequency shift is not an issue, while additional computation might be. Suggested procedure: Create a new StateVariableFilter which will have two well-documented functions: setResonance() and setResonanceQuick() (or something). StateVariable could become deprecated with a note on the available choice.
As for a more generic LowPassFilter, FrequencyFilter or ResonantFilter might be suitable names for a template?

Well, this is not resolved, but I guess it won't be as this would change the behavior of all existing sketches using the stateVariable. Additionnally, the ResonantFilter class offers filters with stable Q. So I would say yes.
