QPixmaps are quite limited in size, though. Not sure what you have in mind... 
Having the audio editor display a large pixmap and edit on that ?

That's ok, it's really just a preview, so I suppose I can safely "display" 
only one of the channels.

Well, that would bypass the small caching scheme I have for previews (that's 
why I need the raw x,y info, really), and it wouldn't be very consistent with 
the NotationView design-wise. I'm not sure this kind of job belongs to the 
AudioFileManager.
