* make SkPath::fConvexity atomicGravatar Mike Klein2017-09-28
| | | | | | | | | | | | | | | | | The TSAN bots fail regularly with races on fConvexity. Very annoying. We used to have this very same problem with SkPath::fFirstDirection until we made it atomic. This does the same to fConvexity. This makes the field as lightly atomic as possible, with all operations using a relaxed memory order. The value of fConvexity isn't guarding any other non-atomic memory or implying any other writes have happened so I don't think we need anything beyond relaxed here.
