We have code that compensates for the scroll offset on screen when
printing, but this didn't work correctly in vertical writing modes.

When printing, we set a rectangle for each page in logical coordinates,
and then transpose it to physical coordinates if writing mode is
vertical. The scroll offset, however, is already in physical
coordinates, so we have to apply this after transposing.

Pagination in vertical writing modes is very broken (crbug.com/881727),
but before we can even get to that problem, we need to make sure that
scrolling doesn't cause problems.
