This code example imports the Tween class and each of the classes in the easing package.
Next, it creates an object that acts as the listener object for a MovieClipLoader instance
that's created in a later section of the code. The listener object defines a single event
listener,
onLoadInit
After the code repositions the image, a new movie clip instance is created within the
movie clip (which contains the dynamically loaded JPEG image). The
target_mc
Drawing API code draws a rectangle with the same dimensions as the JPEG image within
this new movie clip. The new movie clip masks the JPEG image by calling the
MovieClip.setMask()
Tween class to animate, which causes the image to slowly reveal itself.
