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. Requires a gclient sync to pull down libpng. BUG=skia:3257 Committed: https://skia.googlesource.com/skia/+/ca358852b4fed656d11107b2aaf28318a4518b49 (and then reverted) Review URL: https://codereview.chromium.org/930283002
