I just copied the PSD functions and changed "Psd" to "Spectrogram" and added
waterfall sinks to get it working. However I had to remove a call to
"enable_autoscale(bool)" since that function isn't a member of the
waterfall_sink_* classes. Does this sound like the right approach or do I have
to do something special to the data first?
