Nico Weber 2d12647e29 LibPDF: Add FIXME for "was linearized PDF incrementally updated" check ...

It's pretty tricky to do, and also tricky with respect to skipping
trailing bytes after %%EOF: The check requires knowning the full size of
the PDF (which means web servers not sending content lengths are out),
but that size has to be after stripping trailing bytes, which normal
static file servers won't do. So PDF viewers would have to download the
last couple bytes of the PDF unconditionally, then strip trailing bytes
and use the count to figure out the final actual PDF size.

Luckily, we don't incrementally download PDFs from the net but
instead require all data to be available in one chunk, so it's
not currently a problem.
