SkScaledCodec class This class does scaling by using a scanlineDecoder. getScanlines and skipScanlines are used for y sampling, the swizzler is used for x sampling this class is currently only working for png and jpeg images I will update other Codec types to work soon For SkJpegCodec to implement width wise swizzling it now uses a swizzler. I ran performance tests on this change. Here are the performance test results: https://docs.google.com/a/google.com/spreadsheets/d/1D7-Q_GXD_dI68LZO005NNvb8Wq2Ee0wEBEPG72671yw/edit?usp=sharing BUG=skia: Committed: https://skia.googlesource.com/skia/+/0944100ac89f797714eeae0cf2875e2335ff52ee Committed: https://skia.googlesource.com/skia/+/d518ea7927f9f4e0ed5b4134d1b4f48243855a47 Committed: https://skia.googlesource.com/skia/+/b157917507d4f7d2651f0aeb566d31603cc02240 Review URL: https://codereview.chromium.org/1260673002
