Reason for revert: Need to somehow get access to encoders in chrome -- link error on the roll since SkImageEncoder is not built as part of chrome. Original issue's description: > change pixel-serializer to support reencoding existing data > > Trying to evolve this interface so it can > - support rich set of backend-encoders (including ones like ETC1 that can cheaply convert to KXT > - allow for encoding images as well as bitmaps (e.g. for picture serialization) > - perhaps replace SkImageEncoder as an API (assuming we create a factory that returns a serializer given a format) > > BUG=skia: > > Committed: https://skia.googlesource.com/skia/+/13f48dc85aa68a60da66aaf39c93d527d11d1278 TBR=scroggo@google.com,msarett@google.com NOPRESUBMIT=true NOTREECHECKS=true NOTRY=true BUG=skia: Review URL: https://codereview.chromium.org/1371983003
