I agree, but that's what it has been known to do on me in the past, so I 
felt I had to toss that option on the table.  SWAG of course is a 
Scientific Wild Assed Guess. :-)

Besides, isn't the %%DocumentMedia comment a pdf spec rather than a ps 
spec?  I don't recall seeing that in the gs code the last time I walked 
around in it, but %%BoundingBox was all over the place, which was back 
about version 5.10 or so, building it on an amiga. (Now that gives away a 
hint as to my age I guess as I was about 60ish then) That had pdf in it, 
but the spec was then just barely at version 1.2 IIRC.  And it actually 
worked quite well if you had all the t's crossed and the i's properly 
dotted on the command line.  There have been megatons of changes since 
then, making it a whole lot more robust.
