No, I do this call once, when I create the renderer (which is after the user
chooses a couple of files for processing).
This is straight from the QCRenderer reference doc overview. Nothing tells me I
have to subclass the view and do this in the drawRect method, and I don't think
that is necessarily the right way to do this (is it?).
