Functions
static int	R_CullBox (const vec3_t mins, const vec3_t maxs)
	Returns whether if the specified bounding box is completely culled by the view frustum (PSIDE_BACK), completely not culled (PSIDE_FRONT) or split by it (PSIDE_BOTH).
bool	R_CullSphere (const vec3_t centre, const float radius, const unsigned int clipflags)
	Performs a spherical frustum check.

	Returns true if the specified entity is completely culled by the view frustum, false otherwise.
void	R_DrawBspNormals (int tile)
	Developer tool for viewing BSP vertex normals. Only Phong interpolated surfaces show their normals when r_shownormals > 1.
static void	R_RecursiveVisibleWorldNode (const mBspNode_t *node, int tile)
	Recurse down the bsp tree and mark all surfaces as visible for being rendered.
static void	R_RecursiveWorldNode (const mBspNode_t *node, int tile)
	Recurse down the bsp tree and mark surfaces that are visible (not culled) for being rendered.
static void	R_RecurseWorld (const mBspNode_t *node, int tile)
	Wrapper that recurses the bsp nodes but skip the pathfinding nodes.
