Revert of Move sRGB <-> linear conversion components to their own files. (patchset #5 id:80001 of https://codereview.chromium.org/2128893002/ )
Reason for revert: Monotonicity assert is failing on ARM. (Different rsqrt() and invert() precision?) Will investigate a bit tomorrow... might reland with the test TODO. Original issue's description: > Move sRGB <-> linear conversion components to their own files. > > This makes them a little easier to use outside SkColorXform code. > > I've added some notes about how best to use them and their eccentricities, and added a test. > > Ultimately any software sRGB <-> linear conversion should funnel somehow through here. > > BUG=skia: > GOLD_TRYBOT_URL= https://gold.skia.org/search?issue=2128893002 > CQ_EXTRA_TRYBOTS=client.skia:Test-Ubuntu-GCC-GCE-CPU-AVX2-x86_64-Release-SKNX_NO_SIMD-Trybot > > Committed: https://skia.googlesource.com/skia/+/45e58c8807179638980aae8503573b950b844e4c TBR=reed@google.com,msarett@google.com,mtklein@chromium.org # Skipping CQ checks because original CL landed less than 1 days ago.
