pdfTeX only allows some control over the upper right corner of
the media box via `\pdfpagewidth` and `\pdfpageheight` (plus/minus
rounding issues). The lower left corner is always fixed at zero.

The workaround is to increase the output page, move the page
contents accordingly, and to recalculate the coordinates of
the other boxes. Then, the media box, written by pdfTeX,
is correct without the need to specify a second one.
