comparison layer/TimeValueLayer.cpp @ 360:d58701996fae

* Update remaining editable layers to support proper realignment on copy/paste
* Permit pasting when no suitable layer is current: create a new layer on paste
* Add preference for showing the splash screen or not
* Rename spectrogram smoothing prefs (partly following Craig's suggestions)
