Since this document handles the \shipout itself,
viz.
\shipout\box\mybox

all you need to do is adjust the \ht \wd and \dp of
the \box\mybox , and perhaps adjust the \voffset and \hoffset
to position the contents appropriately.

In pdftex the \pdfpagewidth  and  \pdfpageheight  set
the /MediaBox (I think), whereas the /ArtBox or /CropBox have
a greater effect on what you see on-screen in a PDF browser.
That is, changes to \pdfpagewidth  and  \pdfpageheight  may
affect *where* the contents occur on the paper, when you print
the PDF, but need not affect what you see on-screen.

Hope this helps,

Ross
