[tex-live] PDF files cut off using a0poster with current texlive 2009 pretest

[Robin Fairbairns]

i've a vague recollection of needing to tweak ghostscript not to use a
distiller algorithm which determines what page orientation you _really_
meant.

i can't find the original reference, but prodding around in gs docs
suggests that the recipe might have been

  ps2pdf -dAutoRotatePages=/None <file>

worth a try, if nothing else.  i don't seem to have any landscape docs
lying around, to try it with, myself.

page rotation is a tedious topic in pdftex, too.
