[PATCH] CUPS PostScript multipage support

[Jürg Billeter <j bitron ch>]

Hi

After not being able to print multiple pages per sheet with gpdf (and
now evince) for a long time, I've written a little patch for
libgnomeprint to implement this - at least when using the CUPS backend.
Don't know whether that's good enough for upstream but anyway, patch is
attached.

Regards,

Jürg
