rendering lighting everywhere but shadow.
In our case we use a biased stencil clear of 128 to avoid requiring the
-stencil wrap extension (but probably should support it).
+stencil wrap extension (but probably should support it), and to address
+Creative's patent on this sort of technology we also draw the frontfaces
+first, and backfaces second (decrement, increment).
+
+Patent warning:
+This algorithm may be covered by Creative's patent (US Patent #6384822)
+on Carmack's Reverse paper (which I have not read), however that patent
+seems to be about drawing a stencil shadow from a model in an otherwise
+unshadowed scene, where as realtime lighting technology draws light where
+shadows do not lie.
