Class derived from osg::Drawable to handle all DtLightPointNode light points it gathers all the light points and renders them all in a single draw call. Draws all the light points in a single draw call. The light points are added by the DtLightPointNodes to the DtLightPointDrawable and each light point ends up with an entry in the vertex arrays for the light points. In addition to the light points themselves, there are debug light point sprites that are used to draw debug labels above the light points. Because they are using the same state and vertex attributes, the drawing of the labels is extremely fast (so fast I have not been able to see a measurable{ in the F2 stats } difference between having them on or off) The labels are turned on using an imGui checkbox. which is setup by the light point manager.

		const osg::CopyOp &	copyop = `osg::CopyOp::SHALLOW_COPY`
	)

Copy constructor using CopyOp to manage deep vs shallow copy.

virtual makVrv::DtLightPointDrawable::~DtLightPointDrawable ( )

protectedvirtual

Destructor.
