A bug in lcms2 2.13 causes the white background of PS and PDF files to be inadvertently changed to gray.

This (at least) affects viewing PS files on evince (example file attached) and printing PDF files with cups and epson-inkjet-printer-escpr. When printing, this makes the output unusable, as well as significantly increases ink consumption; because of it, I suggest a medium severity.

Fortunately, the bug has already been fixed upstream: <https://github.com/mm2/Little-CMS/commit/fdbfb7694f9d7048d53674b79ddfc38068bfdaf7>.

Since it isn't clear in my original bug report: I have personally tested and been using the upstream patch, and it does indeed fixes both issues I was having.

Additionally, the expected behavior with the attached ps file is for it to have/show/print with a normal white background.
