Nico Weber	4bb29e6ac4	pdf: Add a --debugging-stats flag ... 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: 113 times: Rendering of feature not supported: Type0 font not imp... 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.)	2023-07-24 11:00:01 -04:00
