* Add auto-normalize option to waveform layer
* Various fixes to display of dB/metered levels in waveform layer.  Still need
  to fix to ensure they don't waste half the display
* Add mix channels option to waveform layer
* Use multiple transforms menus, one per transform type -- not sure about this
* Give centroid plugin two outputs, for log and linear frequency weightings
* Show scale units from plugin in time-value display
