Fix page size issue on xetex on Squeeze. The version of xetex on Squeeze does not pass the paper size through to the PDF rendered properly. Following a Googled suggestion, split the rendering into two part, and pass the page size explicitly to the PDF generation. This isn't necessary for the booklet because the output is A4 portrait, the default paper size.
