title: Cocos2d how to scale a sprite without scaling layer? Or, How to scale and crop sprite/layer?
body: <p>iPad App setup: SceneA contains layerA - 1024x768. Push a button in layerA, layerB drops down over top using a CCMoveTo action. LayerB is only 800x600 so you can see layerA behind it (think of an overlayed pause screen type effect). LayerB contains an 800x600 sprite that the user can zoom in on by pressing a button. The zoom effect is simply a combination of CCScaleTo and CCMoveTo to keep it centered on the part it's zooming in on. However, when the sprite scales, so does layerB overtop of layerA. Is there a way to scale the sprite within a contained window?  </p>
