+/*
+Terminology: Stencil Shadow Volume (sometimes called Stencil Shadows)
+An extrusion of the lit faces, beginning at the original geometry and ending
+further from the light source than the original geometry (presumably at least
+as far as the light's radius, if the light has a radius at all), capped at
+both front and back to avoid any problems (extrusion from dark faces also
+works but has a different set of problems)
+
+This is rendered using Carmack's Reverse technique, in which backfaces behind
+zbuffer (zfail) increment the stencil, and frontfaces behind zbuffer (zfail)
+decrement the stencil, the result is a stencil value of zero where shadows
+did not intersect the visible geometry, suitable as a stencil mask for
+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), 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.
+
+
+
+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
+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).
+
+
+
+Terminology: Optimized Stencil Shadow Volume
+A Stencil Shadow Volume that has been processed sufficiently to ensure it has
+no duplicate coverage of areas (no need to shadow an area twice), often this
+greatly improves performance but is an operation too costly to use on moving
+lights (however completely optimal Stencil Light Volumes can be constructed
+in some ideal cases).
+
+
+
+Terminology: Per Pixel Lighting (sometimes abbreviated PPL)
+Per pixel evaluation of lighting equations, at a bare minimum this involves
+DOT3 shading of diffuse lighting (per pixel dotproduct of negated incidence
+vector and surface normal, using a texture of the surface bumps, called a
+NormalMap) if supported by hardware; in our case there is support for cards
+which are incapable of DOT3, the quality is quite poor however. Additionally
+it is desirable to have specular evaluation per pixel, per vertex
+normalization of specular halfangle vectors causes noticable distortion but
+is unavoidable on hardware without GL_ARB_fragment_program.
+
+
+
+Terminology: Normalization CubeMap
+A cubemap containing normalized dot3-encoded (vectors of length 1 or less
+encoded as RGB colors) for any possible direction, this technique allows per
+pixel calculation of incidence vector for per pixel lighting purposes, which
+would not otherwise be possible per pixel without GL_ARB_fragment_program.
+
+
+
+Terminology: 2D Attenuation Texturing
+A very crude approximation of light attenuation with distance which results
+in cylindrical light shapes which fade vertically as a streak (some games
+such as Doom3 allow this to be rotated to be less noticable in specific
+cases), the technique is simply modulating lighting by two 2D textures (which
+can be the same) on different axes of projection (XY and Z, typically), this
+is the best technique available without 3D Attenuation Texturing or
+GL_ARB_fragment_program technology.
+
+
+
+Terminology: 3D Attenuation Texturing
+A slightly crude approximation of light attenuation with distance, its flaws
+are limited radius and resolution (performance tradeoffs).
+
+
+
+Terminology: 3D Attenuation-Normalization Texturing
+A 3D Attenuation Texture merged with a Normalization CubeMap, by making the
+vectors shorter the lighting becomes darker, a very effective optimization of
+diffuse lighting if 3D Attenuation Textures are already used.
+
+
+
+Terminology: Light Cubemap Filtering
+A technique for modeling non-uniform light distribution according to
+direction, for example projecting a stained glass window image onto a wall,
+this is done by texturing the lighting with a cubemap.
+
+
+
+Terminology: Light Projection Filtering
+A technique for modeling shadowing of light passing through translucent
+surfaces, allowing stained glass windows and other effects to be done more
+elegantly than possible with Light Cubemap Filtering by applying an occluder
+texture to the lighting combined with a stencil light volume to limit the lit
+area (this allows evaluating multiple translucent occluders in a scene).
+
+
+
+Terminology: Doom3 Lighting
+A combination of Stencil Shadow Volume, Per Pixel Lighting, Normalization
+CubeMap, 2D Attenuation Texturing, and Light Filtering, as demonstrated by
+the (currently upcoming) game Doom3.
