* Fix master-skia buildGravatar msarett2016-07-19

* Improve naive SkColorXform to half floatsGravatar msarett2016-07-19
| | | | | | | | | | | | | | | | | | | | | | | | This should give us a good baseline to explore using SkRasterPipeline. A particular colorxform to half float drops from 425us to 282us on my desktop.

* Implement fast, correct gamma conversion for color xformsGravatar msarett2016-06-16
| | | | | | | | | | | | | | | | | | | | | | 201295.jpg on HP z620 (300x280, most common form of sRGB profile) QCMS Xform 0.495 ms Skia Old Xform 0.235 ms Skia NEW Xform 0.423 ms Vs Old Code 0.56x Vs QCMS 1.17x So to summarize, we are now much slower than before, but still a bit faster than QCMS. And now we are also far more accurate than QCMS :).

* Optimize color xforms with 2.2 gammas for SSE2Gravatar msarett2016-06-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Because we recognize commonly used gamma tables and parameters as 2.2f, about 98% of jpegs with color profiles will pass through this xform (assuming the dst is also 2.2f). Sample size is 10,322 jpegs. I won't go crazy with performance numbers because this is a work in progress, particularly in terms of correctness. 201295.jpg on HP z620 (300x280, most common form of sRGB profile) Decode Time + QCMS Xform 1.28 ms QCMS Xform Only 0.495 ms Decode Time + Skia Opt Xform 1.01 ms Skia Opt Xform Only 0.235 ms Decode Time + Xform Speed-up 1.27x Xform Only Speed-up 2.11x FWIW, Skia xform time before these optimizations was 41.1 ms. But we expected that code to be slow.

* Use SK_TEST_QCMS to mark qcms test codeGravatar msarett2016-06-06

* Add color correction benchmark - with comparison to qcmsGravatar msarett2016-06-03
--colorImages is empty by default so this won't affect the runtime of the bots. To run locally, use --colorImages <path> and --benchType skcolorcodec. Two takeaways so far: Color correction is (currently) slower than jpeg decodes. Our reference solution is slower than qcms.
