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.
