| | | | | | | | | | | | This kills off some sRGB tables, and lots of call sites can now use SkColor4f::FromColor(). It doesn't seem important to keep this test.

* Move sRGB <-> linear conversion components to their own files.Gravatar mtklein2016-07-08
| | | | | | | | | | | | | | | 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.

(Different rsqrt() and invert() precision?) Will investigate a bit tomorrow... might reland with the test TODO.

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.
