And I hope I did answer that well enough.

I'm not offended, I'm just skeptical that refactoring the xpdf code base
to avoid code duplication is the best use of our time.  If you browse
through the xpdf code base you'll see a lot of duplicated code (for
example, getting values out of a dict, verifying it's the right type and
freeing the Object) that could be reduced to make the code more
manageable.  However, I'd rather spend my time optimizing the rendering
performance or implementing new features.

Introducing new duplicated code is unfortunate, of course, and there may
be some of that in the cairo backend font construction code.  I don't
really see enough shared code between CairoOutputDev.cc and
SplashOutputDev.cc to justify a new layer of abstraction, though.

cheers,
