  A simple (I hope) question:  Suppose I want to define a Postscript image
that always maps itself onto the full size of the paper, regardless of
the actual paper size ?  For example, if I printed the same Postscript
program on both A sized and C sized paper, both would exactly fill the
page.

  If I could somehow find the actual device size _at runtime_, in either
device space or 1/72nd units, then I could easily set up a transformation
which maps some arbitrarily fixed size world space (say [0..1, 0..1]) onto
the whole page.  Unfortunately I don't see any way to get the page size
at runtime.

  Put another way, I want to define my user space relative to the actual
paper size rather than in absolute inches.

  I realize that this isn't the original intent of Postscript, but surely
there must be some way to do it ??

Thanks,
Bob Armstrong
