* 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?

  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
