Initializing the Tween Component

Your tween component must process kTweenerInitializeSelect requests from the Component Manager. Listing 21 shows a function, TweenerInitialize, for processing this request. In this example, the function simply returns. In a more complex example, the function might allocate storage to be used when generating a tween media value.
