pdf: workaround to disable swapping of PDF graphic files
This is needed so that swapping doesn't create excesive amount
of swap files, where each includes the original PDF file, which
would take a lot of temp disk space. This happens because each
graphic object swaps out the original PDF and we create one
graphic object per page.
In a problematic PDF this means it took 20MB (PDF file) * 700
(pages) ~ 14 GB ob disk space.
