+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.
