comparison layer/NoteLayer.cpp @ 42:1bdf285c4eac

* Add "Export Audio File" option
* Make note layer align in frequency with any spectrogram layer on the same
  view (if it's set to frequency mode)
* Start to implement mouse editing for ranges of points by dragging the
  selection
* First scrappy attempt at a vertical scale for time value layer
