Well, except that it _doesn't_ use postscript for display ... That was NeXT
long ago ;-)
There's a lot of Apple Marketing FUD that makesone think that they use some 
sort of "display PDF" but even that is pretty much not true. AFAIK Quartz (their
display engine) uses the same graphic primitives as PDF (which is pretty much
the same as Postscript but also very similar to X primitives) -- so one can
render to "print" with the same code as rendering to "screen".

No, it's a bitmap as well. The code that _draws_ the window uses things like
'moveto', 'lineto', 'fill' et al. One could do similar things than OSX by writing
a X server that renders into memory and uses that to print ....
