Thanks, I was wondering if it was issue worthy or not. I didn't know if
it was something that could be fixed.

I may go ahead and try to patch qvm-convert-pdf then (if I have a free
day or two) seems like it should be relatively easy (with the
information you gave me).

I feel I would just add the option to specify the resolution via a -r
flag (or as part of the arguments), and still allow just the pdf for
backwards compatability.
