Nothing drawn after replacing clutter_actor_set_anchor_point with clutter_actor_set_pivot_point. The main reason is position of graphicsLayer. As I mentioned in bug109037, clutter has a different coordinate system from mac port's, so I think we don't need to recalulate the position after changing anchor position. https://developer.apple.com/library/ios/#documentation/Cocoa/Conceptual/CoreAnimation_guide/CoreAnimationBasics/CoreAnimationBasics.html#//apple_ref/doc/uid/TP40004514-CH2-SW15
