comparison widgets/AudioDial.cpp @ 187:e7cf6044c2a0

* better icon
* support range mappers in thumbwheel
* supply range mapper for vertical zoom from spectrogram
* fix bug in fftmodel for scaled ffts
* make the various widgets all respond to double-click for edit, middle-click
  for reset, ctrl-left-click for reset
