	DtInstancedLightPointUpdate (osgSim::LightPoint lp, osg::ref_ptr< osgSim::LightPointNode > lpn)
	Constructor: stores the lightpoint and lightpointnode associated with this object there is one of these updates for each light point on instanced geometry.
bool	isShadowCamera (osg::RenderInfo renderInfo) const
	checks to see if this render info is for a shadow camera. This is used to not draw instanced light points when it is a shadow camera
virtual bool	isSmallFeature (osg::Matrixf drawableMatrix, osg::ref_ptr< osg::Camera > camera)
	Check to see if this instance of the drawable is smaller than the small feature culling pixel size.
virtual bool	processSector (osg::Matrixd drawableMatrix)
	Check to see if the camera location is such that this light point should be drawn based on the light point's sector.
virtual void	update (osg::NodeVisitor *nv, osg::Drawable *drw)
	Update callback for the geometry. Handles blinking lights and sets up the arrays for the geometry.
