Functions
static void	R_UpdateMaterial (material_t *m)
	Materials "think" every few milliseconds to advance animations.
static void	R_StageGlow (const materialStage_t *stage)
static void	R_StageLighting (const mBspSurface_t surf, const materialStage_t stage)
	Manages state for stages supporting static, dynamic, and per-pixel lighting.
static void	R_StageVertex (const mBspSurface_t surf, const materialStage_t stage, const vec3_t in, vec3_t out)
	Vertex deformation.
static void	R_StageTextureMatrix (const mBspSurface_t surf, const materialStage_t stage)
	Manages texture matrix manipulations for stages supporting rotations, scrolls, and stretches (rotate, translate, scale).
static void	R_StageTexCoord (const materialStage_t *stage, const vec3_t v, const vec2_t in, vec2_t out)
	Generates a single texture coordinate for the specified stage and vertex.
static void	R_StageColor (const materialStage_t *stage, const vec3_t v, vec4_t color)
	Generates a single color for the specified stage and vertex.
static void	R_SetSurfaceStageState (const mBspSurface_t surf, const materialStage_t stage)
	Manages all state for the specified surface and stage.
static void	R_DrawSurfaceStage (mBspSurface_t surf, materialStage_t stage)
	Render the specified stage for the surface. Resolve vertex attributes via helper functions, outputting to the default vertex arrays.
void	R_DrawMaterialSurfaces (mBspSurfaces_t *surfs)
	Iterates the specified surfaces list, updating materials as they are encountered, and rendering all visible stages. State is lazily managed throughout the iteration, so there is a concerted effort to restore the state after all surface stages have been rendered.

static void	R_CreateMaterialData (void)
