Just upside down in quartz(type= "pdf").

Yes, I can read the help (I even wrote some of that)!  If by 'previous' 
you mean in 2.6.2, it was a different quartz device and quartz.save() did 
not use dev.copy (it was part of the R.app GUI's quartz() device).

So I don't see your point.  Mine was that I added "quartz" options to e.g 
png() because quartz(type = "png") worked at that point, but not to 
dev.copy2pdf() because quartz(type = "pdf") produced useless output at 
that time.
