@brief A transition which peels back the bottom right hand corner of a scene
to transition to the scene beneath it simulating a page turn.

This uses a 3DAction so it's strongly recommended that depth buffering
is turned on in Director using:

 Director::sharedDirector()->setDepthBufferFormat(kDepthBuffer16);
