/** Encapsulates the current applied OpenGL modes, attributes and vertex arrays settings,
* implements lazy state updating and provides accessors for querying the current state.
* The venerable Red Book says that "OpenGL is a state machine", and this class
* represents the OpenGL state in OSG. Furthermore, \c State also has other
* important features:
* - It works as a stack of states (see \c pushStateSet() and
* \c popStateSet()). Manipulating this stack of OpenGL states manually is
* seldom needed, since OSG does this in the most common situations.
* - It implements lazy state updating. This means that, if one requests a
* state change and that particular state is already in the requested state,
* no OpenGL call will be made. This ensures that the OpenGL pipeline is not
* stalled by unnecessary state changes.
* - It allows to query the current OpenGL state without calls to \c glGet*(),
* which typically stall the graphics pipeline (see, for instance,
* \c captureCurrentState() and \c getModelViewMatrix()).
