DESCRIPTION
     SoLight is the abstract base class for all light nodes. A light node
     defines an illumination source that may affect subsequent shapes in the
     scene graph, depending on the current lighting style. Light sources are
     affected by the current transformation. A light node under a separator
     does not affect any objects outside that separator.

     You can also use a node kit to create a light; see the reference page for
     SoLightKit.

FIELDS
     SoSFBool		 on
	  Determines whether the source is active or inactive. When inactive,
	  the source does not illuminate at all.

     SoSFFloat		 intensity
	  Illumination intensity of light source. Valid values range from 0.0
	  (no illumination) to 1.0 (maximum illumination).

     SoSFColor		 color
	  Light source illumination color.

FUNCTIONS
     SoType		 SoLightGetClassTypeId()
	  Returns type identifier for this class.

ACTION BEHAVIOR
     SoGLRenderAction
	  Activates this light (if so specified) during traversal. All shape
	  nodes that come after this light in the scene graph are illuminated
	  by this light.

FILE FORMAT/DEFAULTS
     This is an abstract class. See the reference page of a derived class for
     the format and default values.
