comparison layer/SpectrumLayer.cpp @ 290:3101c68a00c1

* Restore Scale setting which had mistakenly disappeared from spectrum
* Some tweaks to spectrum peaks
* Make spectrum default to 4096/75%... or is that overdoing it?
* Show harmonic cursor even during playback if in measure mode and mouse in
  relevant pane
* Avoid crash when trying to measure a non-layer
* Various adjustments to some icons to make them look better in white-on-black
  schemes
