This reverts commit2e018f548d. Reason for revert: doesn't appear to have been the roll problem. Original change's description: > Revert "clamp to premul when reading premul sRGB" > > This reverts commit04e10da836. > > Reason for revert: roll? > > Change-Id: Id0a8dcd62763bd6eddde120c513ca97e098a4268 > Reviewed-on: https://skia-review.googlesource.com/6022 > Commit-Queue: Mike Klein <mtklein@chromium.org> > Reviewed-by: Mike Klein <mtklein@chromium.org> > TBR=mtklein@chromium.org,reviews@skia.org,brianosman@google.com NOPRESUBMIT=true NOTREECHECKS=true NOTRY=true Change-Id: I399ca5e728ce6766c6707682c4c6b685681ffdeb Reviewed-on: https://skia-review.googlesource.com/6025 Commit-Queue: Mike Klein <mtklein@chromium.org> Reviewed-by: Mike Klein <mtklein@chromium.org>
