typedef PointType< T, N >::point_t	point_t
	The type of a point with the same dimension as this ray; a `Vec<T,N>` if `N` is greater than 1; or a `T` if `N` is 1.

Public Member Functions
	Ray ()
	Construct a ray through the origin directed along the +x axis.

	Ray (point_t o, point_t v)
	Construct a ray through the point `o` with direction `v`.

Ray< T, N >	operator- () const
	Return a ray pointing in the opposite direction.

template<index_t M>
Ray< T, M >	resized () const
	Change the dimensionality of this Ray.

point_t	at_distance (T d) const
	Return the point along this ray's direction, at distance `d` from the ray origin.

point_t	at_multiple (T s) const
	Return the point `origin + s * direction`.

point_t	neg () const
	Return ray pointing in the opposite direction.

point_t	project (point_t p) const
	Find the point on the ray nearest to `p` by orhtogonally projecting `p` onto it.

T	sdf (point_t p) const
	Signed distance from `p` to the nearest point on the ray.

T	dist2 (point_t p) const
	Compute the square of the distance from `p` to the nearest point on the ray.
