  "message": "calculate k with one fewer divide\n\nUpdated the tests to print out how close we are to roundtripping 1.0f.\n\nWith this change, the computed inverses actually become closer to the\ngoal than the current hardcoded inverse:\n\n    ~/skcms (master↑1|✔) $ out/clang/tests\n    0x1.fff50ap-1 0.999916, -1403 ulps from 1.0f   (hardcoded)\n    0x1.0001p+0 1.00002, 128 ulps from 1.0f        (sRGB2)\n    0x1.fffc0ap-1 0.99997, -507 ulps from 1.0f     (inv2)\n\nThis a^-g version also beats 1/(a^g).\n\nSince this quality is now better than the hardcoded version, I\u0027m\nthinking of removing the hardcoded sRGB inverse and replacing it with a\nonce\u0027d runtime call to invert.  That\u0027d at least make the two obvious\nways of getting at the inverse sRGB curve agree exactly.\n\nGuarded by SKCMS_LEGACY_TF_INVERT.\n\nChange-Id: Ic6b301b30747b2483e5354a5cbf18065e6ef0e07\nReviewed-on: https://skia-review.googlesource.com/c/181737\nReviewed-by: Brian Osman \u003cbrianosman@google.com\u003e\nCommit-Queue: Mike Klein \u003cmtklein@google.com\u003e\n",
