[PATCH] use "." as fraction separator independently of locale settings

[Vlad Harchev <hvv hippo ru>]

 Hi, 

 Here is a patch against 0.25 that forces pdf generator to use "." as fraction
seprarator, independant of the locale's settings (e.g., under russian locales
fraction separator is comma). Of course, .pdf that use anything but dot as
fraction seprator can't be opened by any .pdf reader out there.

 It would be nice if this patch went into gnome-print shipped with
gnome-1.4 - what do you think?
 
 Best regards,
  -Vlad
