comparison view/Overview.cpp @ 274:b9380f679f70

* Fix centre line position
* Fix failure to update overview when generating peaks from wav file
* Provide y-coordinate scale values and differences for spectrum measurement
  mode, and fix values for waveform (inc dB for both)
* Add Printer colour scheme (may be futile)
