Reason for revert: plenty of data Original issue's description: > Sketch DM refactor. > > BUG=skia:3255 > > > I think this supports everything DM used to, but has completely refactored how > it works to fit the design in the bug. > > Configs like "tiles-gpu" are automatically wired up. > > I wouldn't suggest looking at this as a diff. There's just a bunch of deleted > files, a few new files, and one new file that shares a name with a deleted file > (DM.cpp). > > NOTREECHECKS=true > > Committed: https://skia.googlesource.com/skia/+/709d2c3e5062c5b57f91273bfc11a751f5b2bb88 TBR=bsalomon@google.com,mtklein@chromium.org NOTREECHECKS=true NOTRY=true BUG=skia:3255 Review URL: https://codereview.chromium.org/853883004
