Sets the number of pages in the document.
This must be set to a positive number
before the rendering starts. It may be set in a
"begin-print" signal hander.
Note that the page numbers passed to the
"request-page-setup"
and "draw-page" signals are 0-based, i.e. if
the user chooses to print all pages, the last ::draw-page signal
will be for page n_pages - 1.
