   But we reinvent it in library. According to your approach, every app
   should reimplement it separately.

Having a Caanvas that applications -- even just GNOME applications --
can draw to that then generates Postscript is very much a worthy
goal.  Likewise a layer that interprets PPD files to provide an
abstract interface for applications.  The problem that Mike and I have
is with your insistence on doing the final rendering yourselves.  Mike
and I have been trying to explain just why doing the rendering
yourselves is a bad idea.

Postscript is a perfectly good IL.  IMHO, you should concentrate on
the abstractions needed to help applications generate the IL.  GNOME
is a front end system.

   Consumer-level holographic printers would be out before 2005
   As Y2K showed, software usually lasts longer.

That's entirely missing the point.  Maybe they will (my guess would be
3-5 years later, but that's irrelevant); Mike's point is just as
valid.  The point is that for the driver to be in the APPLICATION
layer it's all wrong.

All that you need to do to support such a printer is extend the
Caanvas to support three-dimensional drawing.  It's a safe bet that
folks like Raph or Jean-Marc Verbavatz or Thomas Tonino or myself
would write the appropriate CUPS driver, and then you're all set.
