Implementations can't always cause a synchronous paint. On some platforms 
you can only paint when you are idling. So it seems better not to provide 
this API. Also, since some implementations run JavaScript on the main 
thread, it's bad practice to run a script for an extended period of time 
(which would be the use case for forceRedraw). So I don't think 
forceRedraw() is a good idea.
