iOS objects that implement the
EAGLDrawable protocol can be used as a rendering surface and displayed to the screen by an
EAGLContext object. In iOS 2.0, this protocol is implemented only by the
CAEAGLLayer class, but in the future other classes may choose to implement the protocol. The
EAGLDrawable protocol is not intended to be implemented by objects outside of the iOS.
