Submitted By: Ken Moffat <ken at linuxfromscratch dot org>
Date: 2012-08-22
Initial Package Version: 0.1.8
Upstream Status: Varies
Origin: Found at fedora.
Description: Three fixes found at fedora.  For the first (only glib.h
can be included directly, with recent glib), we used to use a sed - but
the other two fixes need patches so I've put them all together.

 Second part is from upstream and fixes trashed colours
Upstream: http://trac.emma-soft.com/epdfview/changeset/367/trunk
Fixes bug: https://bugzilla.redhat.com/show_bug.cgi?id=745483

 Third part is the most critical - from Jiri Popelka, found at
https://bugzilla.redhat.com/show_bug.cgi?id=841880 - looks as if fedora
haven't applied it yet.  It solves building with cups-1.6.
