The gnome_print_scale () call makes no difference.

I had another look at the PDF, and it seems that (a) the physical size
of the page is wrong (A4 * 96/72), and (b) the character advances are
wrong, everything else seems correct. I know what is causing the latter
problem; the advances in the pango structures are stored in device
units, which were calculated for the screen. I know how to fix it and
will do tonight.

As for (a), I have not had chance to investigate.
