Should we make threadSafeProxy thread safe itself?

[bsalomon, 2016/03/08 19:49:32]

GrContext is not thread-safe so I don't think this method should be expected to
be thread-safe and I think it'll get complicated to document which methods are
thread safe.

+GrContextThreadSafeProxy* GrContext::threadSafeProxy() {
+    if (!fThreadSafeProxy) {
+        fThreadSafeProxy.reset(new GrContextThreadSafeProxy(fCaps, this->uniqueID()));
+    }
+    return SkRef(fThreadSafeProxy.get());
