[XeTeX] Synching PDF paper size with typesetting size

[Martin Schröder]

> Typesets fine... But the output PDF is still letter size--slightly annoying in terms of visual impressions. Is there a way to get tell the system to adjust the PDF output size to match? Either within the TeX source or as an option at typeset time (in this case, done through TeXShop with XeLaTeX)?
