comparison layer/TimeValueLayer.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

 
     // looks like save/restore doesn't deal with this:
     paint.setRenderHint(QPainter::Antialiasing, false);
