-// The CCSchedulerStateMachine decides how to coordinate main thread activites
-// like painting/running javascript with rendering and input activities on the
-// impl thread.
-//
-// The state machine tracks internal state but is also influenced by external state.
-// Internal state includes things like whether a frame has been requested, while
-// external state includes things like the current time being near to the vblank time.
-//
-// The scheduler seperates "what to do next" from the updating of its internal state to
-// make testing cleaner.
