John Emmas 169e15483a Implement a derived function for 'GainMeter::redraw_metrics()'
I'm not sure why exactly but at this line in 'GainMeter::set_controls ()' :-

    model_connections, invalidator (*this), boost::bind (&GainMeter::redraw_metrics, this), gui_context()

MSVC will not allow us to pass a base class function to boost::bind(). I tried explicitly specifying the base class and I also tried making the function public / making it virtual etc but the only thing which works is to implement a derived function.

It's somehow related to changing the signal from 'TypeChanged' to 'MeterTypeChanged' but I don't entirely understand why... :-(
