Functions
void	R_DrawSurfaces (const mBspSurfaces_t surfs, glElementIndex_t indexPtr)
	General surface drawing function, that draw the surface chains.
void	R_DrawMaterialSurfaces (const mBspSurfaces_t surfs, glElementIndex_t indexPtr)
	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.
void	R_SetSurfaceBumpMappingParameters (const mBspSurface_t surf, const image_t normalMap, const image_t *specularMap)
bool	R_CullMeshModel (const entity_t *e)
	Checks whether a model is visible in the current scene.
void	R_DrawModelParticle (modelInfo_t *mi)
	Renders a particle model for the battlescape.
void	R_DrawBspNormals (int tile)
	Developer tool for viewing BSP vertex normals. Only Phong interpolated surfaces show their normals when r_shownormals > 1.
bool	R_CullBspModel (const entity_t *e)
	Returns true if the specified entity is completely culled by the view frustum, false otherwise.
bool	R_CullSphere (const vec3_t centre, const float radius, const unsigned int clipflags)
	Performs a spherical frustum check.
void	R_GetLevelSurfaceLists (void)
	Fills the surface chains for the current worldlevel and hide other levels.
void	R_GetEntityLists (void)
	Primary entry point for drawing all entities.
void	R_DrawInitLocal (void)
	Loads some textures and init the 3d globe.

void	R_ClearBspRRefs (void)
void	R_AddBspRRef (const mBspModel_t *model, const vec3_t origin, const vec3_t angles, const bool forceVisibility)
	Adds bsp render references.
void	R_RenderOpaqueBspRRefs (void)
	Draw all simple opaque bsp surfaces with multitexture enabled and light enabled.
void	R_RenderOpaqueWarpBspRRefs (void)
	Draw all warped opaque bsp surfaces via warp shader.
