Not relevant to this CL, but why 'set..' not 'Set..'?

Who knows? setFftSize didn't get changed by the Great Blink Renaming, so I'm not
going to do that.  Maybe because this is the method that is exposed to JS to
setting the fftSize attribute?

   // minDecibels and maxDecibels have default values.  Set both of the values
   // at once.
