The SoGLViewingMatrixElement class is used to store the current viewing matrix.
The viewing matrix contains the inverse camera coordinate system matrix. The camera coordinate system is built from the field values in the current SoCamera (currently either SoPerspectiveCamera or SoOrthographicCamera) and any transformations prior to the camera in the scene graph.

This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.

This method is called every time a new element is required in one of the stacks. This happens when a writable element is requested, using SoState::getElement() or indirectly SoElement::getElement(), and the depth of the current element is less than the state depth.
Override this method if your element needs to copy data from the previous top of stack. The push() method is called on the new element, and the previous element can be found using SoElement::getNextInStack().
Reimplemented from SoElement.
This method is callled when the state is popped, and the depth of the element is bigger than the current state depth. pop() is called on the new top of stack, and a pointer to the previous top of stack is passed in prevTopElement.
Override this method if you need to copy some state information from the previous top of stack.
Reimplemented from SoElement.

Returns the node id of the current camera node. This is used by SoGLModelMatrixElement to detect a change in the viewing matrix inside an SoTransformSeparator node.
Returns the matrix that should be used by SoGLModelMatrixElement when the transformation should be reset during traversal (typically when encountering an SoResetTransform node). It is not sufficient to simply load the viewing matrix, since the transformations that were applied before the camera needs to be accounted for.
This function is an extension for Coin, and it is not available in the original SGI Open Inventor v2.1 API.

Sets the current viewing matrix.
