Reason for revert: Breaks canary builds. Will reland after the Chromium change lands. Original issue's description: > Remove SK_SUPPORT_LEGACY_DEEPFLATTENING. > > This was needed for pictures before v33, and we're now requiring v35+. > > Will follow up with the same for skia/ext/pixel_ref_utils_unittest.cc > > BUG=skia: > > Committed: https://skia.googlesource.com/skia/+/52c293547b973f7fb5de3c83f5062b07d759ab88 TBR=reed@google.com,mtklein@chromium.org NOTREECHECKS=true NOTRY=true BUG=skia: Review URL: https://codereview.chromium.org/768183002
