NSOpen object using the
init method and attach the resulting object to an OpenGL context with the
set method of
NSOpen object wraps a low-level, platform-specific Core OpenGL (CGL) pixel buffer object. Your application can retrieve the CGL pixel buffer by calling the
CGLPBuffer method. For more information on the underling CGL pixel buffer, see CGL.
