[Gnome-print] wishitem: emit media size and orientation in generated PS

[Vlad Harchev <hvv hippo ru>]

 Hi,

 Just one more feature that would be useful in gnome-print - it should emit
media size and orientation in the PS prologue (at least orientation, please).
Without it, it's very hard to read .ps generated for landscape oriented
documents (from e.g. gnumeric) using GV. Emitting media size would help a lot
too (at least user will be able to see what are real margins, etc).

 It's trivial to add IMO - just see look at the prologue generated by dvips
for example (while varying media size and orientation).

 Thanks.

 Best regards,
  -Vlad
