// without any concurrency issues.  ThreadUnsafeCommitState is shared data that
// is *not* copied to the compositor. Main thread code must take care not to
// modify anything reachable from ThreadUnsafeCommitState while commit is
// running on the impl thread, typically by adding calls to
// LayerTreeHost::WaitForCommitCompletion() before attempting to mutate state.
