Correct, ipdf is the "front end", sort of a "PDF Panel" that renders from the popper libraries.
Most of the ipdf code will be retained, I'll just slide in a djvu rendering library.
Once its working it might be interesting to make a PDF/DJVU multi-capable app.
Next would be to produce one that was tabbed so one could have several documents open at the same time. Or maybe I have the order backwards (tabs then multi-format).
