Tries to render all pages of a PDF and then produces a report on which
unimplemented things were encountered.

Example, for pdf_reference_1-7.pdf:

        on pages: 170 (3x) 217 (2x) 250 (9x) 252 (2x) 329 (6x)...
    21 times: Rendering of feature not supported: unknown color space
        on pages: 489 (4x) 490 (5x) 491 (3x) 492 (5x) 493 (4x)
    4 times: Rendering of feature not supported: CCITTFaxDecode Filte...
        on pages: 494 (4x)

(Actually, rendering crashes for some page in that file at the moment.
This was with a local change to only render the first 800 pages to work
around that. So this is also good for finding crashes.)
