Detailed Description
CC3OpenGLES11StateTrackerViewport tracks the viewport GL state.
The originalValueHandling property is set to kCC3GLESStateOriginalValueReadOnceAndRestore, which will cause the state to be automatically read once, on the first invocation of the open method, and to be automatically restored on each invocation of the close method.
