[poppler] poppler-0.3.1

[Kristian Høgsberg]

Hi,

I've just done a quick bug fix release - poppler-0.3.1.  There's a
couple of fixes for some crashers in there as well as the fix for
missing qt/poppler-private.h in the SOURCES list.  Plus Jeff's patch to
use zlib is in this release.

I'll be porting the cairo backend to CVS head now, which means that we
should be able to do the font caching properly.  However, this also
means that the cairo backend will only compile against CVS cairo, but
hopefully cairo-0.5 shouldn't be too far off.

cheers,
Kristian
