  + cairo-pdf-add-missing-flush.patch: Fixes PDF generation
    see https://gitlab.freedesktop.org/cairo/cairo/issues/342

I have a PDF document here that prints as total bogus when processed
with cups filters (using libcairo, e.g. from evince) without this patch.
Unfortunately I can't share the file for privacy reasons. 
See also https://github.com/OpenPrinting/cups-filters/issues/93.
