Correct problem with page(1) reported by Peter Cejchan, which turned out
to be incorrect handling of (rare) PDF files with a CropBox inset within
the MediaBox.  The accompanying demo file croptest.ps (which I don't
expect you to copy to sources) illustrates the effect: it prints text
in four orientations, translated to each quadrant of the page - 16 pages
in all.  When translated with ps2pdf and viewed with page, the result
should be cropped to the correct quadrant and displayed with text upright.

    Thanks for tracking this down.
