  "message": "Remove the pdfium_diff --fuzzy option and its tolerance parameters\n\nWith pngdiffer deciding every image comparison from the measurements\nprinted by --metrics, the tolerance machinery inside pdfium_diff has\nno remaining caller. Delete the --fuzzy flag, the parsing of its\noptional delta, mse and win_mse fields, and the four tolerance\nparameters threaded through PixelsDifferent() and CompareImages().\nA pixel now counts as different if it differs at all.\n\nDrop the shadow validation in pngdiffer along with the c_result field\nit compared against. The check has served its purpose, and without\ntolerances in C++ a fuzzy-matched test would report a Python pass\nagainst a C++ failure on every run.\n\nThe fuzzy limits themselves are unchanged. pngdiffer still parses the\nfuzzy\u003d suppression token, and the C++ embedder tests still take the\nlimits from kFuzzyDiffOptions in testing/utils/pixel_diff_util.h.\n\nAlso report win_mse in the fuzzy failure reason, since it can be the\nsole cause of a failure and the Python verdict is now the only one.\n\nTAG\u003dagy\nCONV\u003dcb006656-4ac4-4ff7-9705-478ba4c6a291\n\nChange-Id: I8effaad520fc88d0537219c831bc4d335874a178\nReviewed-on: https://pdfium-review.googlesource.com/c/pdfium/+/158191\nReviewed-by: Lei Zhang \u003cthestig@chromium.org\u003e\nCommit-Queue: Tom Sepez \u003ctsepez@chromium.org\u003e\n",
