 // 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.
