i suppose we must agree to differ here.  acrocr at p reader knows where
the document is going to print -- in the case of typical
(la)tex/context documents, nowhere near the physical edge of the paper
-- but _still_ shrinks the document to fit the white margins onto the
printable area of the page.

of course, as far as adobe is concerned, the reference implementation
of an acrobat handler is their stupid reader.  so if you produce a
reader that fails to behave stupidly, it's not "standard conformant".

at least they now allow us to set no shrink via the command line (in
5.0.8 on linux, possibly also in the appalling 6.* on widnoze and
macs).
