DESCRIPTION
     The SoBlinker class is derived from SoSwitch, so it selects one of its
     children to traverse. Using engines connected to the realTime global
     field, the whichChild field is animated over time. If the node has only
     one child, whichChild toggles between SO_SWITCH_NONE and 0, causing the
     child to be switched on and off repeatedly. If the node has more than one
     child, they are cycled through continuously.

FIELDS
     SoSFFloat           speed
          Defines the speed of the blinker, in cycles per second.

     SoSFBool            on
          Allows applications to enable or disable the blinking easily.


METHODS
                         SoBlinker()
          Creates a blinker node with default settings.

     static SoType       getClassTypeId()
          Returns type identifier for this class.


ACTION BEHAVIOR
     SoGLRenderAction, SoCallbackAction, SoGetBoundingBoxAction,
     SoGetMatrixAction, SoHandleEventAction, SoRayPickAction, SoSearchAction
          Same as for SoSwitch.
