1. 1) Player events are dispatched – This includes events dispatched by the Timer, Mouse, ENTER_FRAMEs, URLLoader, etc…

2. 2) User code is executed – Any code listening to events dispatched by step 1 are executed at this stage.

3. 3) RENDER event is dispatched – This special event is dispatched when the user calls stage.invalidate() during normal user code operation.

4. 4) Final user code is executed – User code listening specifically for step 3 is executed at this point.

5. 5) Player renders changes to the display list.
