Reason for revert: underlying problem with portable refs deleted more than once fixed Original issue's description: > Revert of make gm background colors 565 compatible (patchset #2 id:20001 of https://codereview.chromium.org/1176243006/) > > Reason for revert: > breaks many bots with refcnt error > > Original issue's description: > > make gm background colors 565 compatible > > > > Change a batch of GM tests to convert their background color > > so that it is representable in 8888 and 565. > > > > Enable portable text in those same tests to minimize platform > > differences. > > > > In a couple of bitmap tests, use portable typefaces instead of > > choosing 'Times' which may or may not be available on the platform. > > > > R=borenet@google.com > > > > Committed: https://skia.googlesource.com/skia/+/be7f768a357aefb39c42d24b81b24d647bb6ab70 > > TBR=borenet@google.com > NOPRESUBMIT=true > NOTREECHECKS=true > NOTRY=true > > Committed: https://skia.googlesource.com/skia/+/0bdb08b1ba8fbd18c4838f86a23f1ef4b3a3bfdf TBR=borenet@google.com NOPRESUBMIT=true NOTREECHECKS=true NOTRY=true Review URL: https://codereview.chromium.org/1182403003
