	Returns the proxy for the currently active viewer (might be NULL!)
static void	setCursor (SoState *state, int shapeID)
	Convenience method which calls the corresponding method of SoViewerProxy (or does nothing if the proxy is NULL)
static double	getDevicePixelRatio (SoState *state)
	Convenience method which calls the corresponding method of SoViewerProxy.
static void	setViewerProxyCB (void *userData, SoAction *action)
	this callback can be used with SoCallback nodes and simply sets the SoViewerProxy given as userData
