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