And what does any of this have to do with XQuartz?  That is the 
third-party X11 server/sub-system for OS X.  Perhaps the quartz() device 
was meant ....

For the sake of those reading the archives, can we have a much clearer 
statement of the actual problem?  There might be better solutions, 
including quartz(type = "pdf') (which is closer to what 'Save As' from 
the quartz() device does).
