//! specifies a spot light node of VRML nodes specifying
//! properties of lights.
//! This node defines a spotlight light source.
//! A spotlight is placed at a fixed location in 3D-space
//! and illuminates in a cone along a particular direction.
//! The intensity of the illumination drops off exponentially
//! as a ray of light diverges from this direction toward
//! the edges of cone.
//! The rate of drop-off and agle of the cone are controlled
//! by the dropOfRate and cutOffAngle
//! Color is written as an RGB triple.
//! Light intensity must be in the range 0.0 to 1.0, inclusive.
