Find the minimum distance between a primitive and a point.

GU_API bool GUminimumDistPrimPrim	(	const GEO_Primitive &	prim1,
		const GEO_Primitive &	prim2,
		float	distmax = 1E17F,
		float *	distance = 0,
		float *	u1 = 0,
		float *	v1 = 0,
		float *	u2 = 0,
		float *	v2 = 0,
		bool	accurate = true
	)

Find the minimum distance between two primitives. (u1,v1) is place on prim1, (u2,v2) is place on prim2. NOTE: This treats polygon primitives as just their edges, not filled polygons.
