Prelight models

"_prelight_<lightname>", ie "_prelight_light1"

Static surfaces available to dmap will be processed to optimized
shadow and lit surface geometry

Entity models are never prelighted.

Light entity can have a "noPrelight 1" key set to avoid the preprocessing
and carving of the world.  A light that will move should usually have this
set.

Prelight models will usually have multiple surfaces

Shadow volume surfaces will have the material "_shadowVolume"

The exact same vertexes as the ambient surfaces will be used for the
non-shadow surfaces, so there is opportunity to share


Reference their parent surfaces?
Reference their parent area?


If we don't track parts that are in different areas, there will be huge
losses when an areaportal closed door has a light poking slightly
through it.

There is potential benefit to splitting even the shadow volumes
at area boundaries, but it would involve the possibility of an
extra plane of shadow drawing at the area boundary.


interaction	lightName	numIndexes

Shadow volume surface

Surfaces in the world cannot have "no self shadow" properties, because all
the surfaces are considered together for the optimized shadow volume.  If
you want no self shadow on a static surface, you must still make it into an
entity so it isn't considered in the prelight.


r_hidePrelights
r_hideNonPrelights



each surface could include prelight indexes

generation procedure in dmap:

carve original surfaces into areas

for each light
	build shadow volume and beam tree
	cut all potentially lit surfaces into the beam tree
		move lit fragments into a new optimize group

optimize groups

build light models
