Thomas mentioned that he may be able to convince Qt to add support for 
post-filtering (which is what booklets use), but pre-filtering appears a 
no-go (and no-one has pointed out a use-case yet).  

The problem isn't adding filtering to the print system, which Qt could do on 
any platform, its that almost all our filters depend on the internal file 
format being postscript, which is not true on Win.  I'm not clear on whether 
QPrinter even supports ps workflows internally on *nix.

However, that said, I don't see any reason why we should loose a great feature 
under *nix just because the win guys can't do it.  We have to give them an 
incentive to switch :-).

If QPrinter adds support for filtering, and can use ps internally on *nix, or 
someone comes up with a way of filtering cross-platform, then we can tailor 
the platform dialogs appropriately to show only what they support on that 
platform.  We may loose it short term, but hopefully regain it later.
