Subject: [PATCH] Apply debian upstream patch 0135-fix_pdf_floats
Original patch commentary:
Description: Fix floats in PDF and PostScript
Set LC_NUMERIC to POSIX before printing floats when building
PostScript or PDF output.
Author: Julien BLACHE <jblache@debian.org>
Forwarded: yes
------------
Looks like float printing format is affected by the current locale.
Ensures that we always get POSIX formatting of floats.
