Terminology: Stencil Light Volume (sometimes called Light Volumes)
Similar to a Stencil Shadow Volume, but inverted; rather than containing the
-areas in shadow it contanis the areas in light, this can only be built
+areas in shadow it contains the areas in light, this can only be built
quickly for certain limited cases (such as portal visibility from a point),
but is quite useful for some effects (sunlight coming from sky polygons is
one possible example, translucent occluders is another example).
