Reason for revert: Breaking windows bots all over the place :( Original issue's description: > Add SkCodec, including PNG implementation. > > DM: > Add a flag to use SkCodec instead of SkImageDecoder. > > SkCodec: > Base class for codecs, allowing creation from an SkStream or an SkData. > An SkCodec, on creation, knows properties of the data like its width and height. Further calls can be used to generate the image. > TODO: Add scanline iterator > > SkPngCodec: > New decoder for png. Wraps libpng. The code has been repurposed from SkImageDecoder_libpng. > TODO: Handle other destination colortypes > TODO: Substitute the transpose color > TODO: Allow silencing warnings > TODO: Use RGB instead of filler? > TODO: sRGB > > SkSwizzler: > Simplified version of SkScaledSampler. Unlike the sampler, this object does no sampling. > TODO: Implement other swizzles. > > BUG=skia:3257 > > Committed: https://skia.googlesource.com/skia/+/ca358852b4fed656d11107b2aaf28318a4518b49 TBR=reed@google.com,djsollen@google.com,msarett@google.com,mtklein@google.com NOPRESUBMIT=true NOTREECHECKS=true NOTRY=true BUG=skia:3257 Review URL: https://codereview.chromium.org/972743003
