The above is not complete because "renderAtTime:" doesn't know how
to handle a nil value for the time. I'm not sure what the best
solution is, so I decided to simply ignore the incoming time value
entirely. In renderAtTime:, here is what I changed:
I don't think you should be using 0 as if the composition is
currently rendering far in time, you're gonna have it jump backward
and this might affect performance.
Just store the time of the latest rendered frame and re-use it.
