DESCRIPTION
     This node represents a 3D shape formed by constructing polylines from
     vertices located at the coordinates specified in the vertexProperty field
     (from SoVertexShape), or the current inherited coordinates. For optimal
     performance, the vertexProperty field is recommended.

     SoIndexedLineSet uses the indices in the coordIndex field (from
     SoIndexedShape) to specify the polylines. An index of SO_END_LINE_INDEX
     (-1) indicates that the current polyline has ended and the next one
     begins.

     The coordinates of the line set are transformed by the current cumulative
     transformation. The lines are drawn with the current light model and
     drawing style (drawing style FILLED is treated as LINES).

     Treatment of the current material and normal binding is as follows: The
     PER_PART binding specifies a material or normal for each segment of the
     line. The PER_FACE binding specifies a material or normal for each
     polyline. PER_VERTEX specifies a material or normal for each vertex. The
     corresponding _INDEXED bindings are the same, but use the materialIndex
     or normalIndex indices (see SoIndexedShape). The default material binding
     is OVERALL. The default normal binding is PER_VERTEX_INDEXED

     The current complexity value has no effect on the rendering of indexed
     line sets.

FUNCTIONS
     SoIndexedLineSet *  SoIndLSetCreate()
          Creates an indexed line set node with default settings.

     SoType              SoIndLSetGetClassTypeId()
          Returns type identifier for this class.


ACTION BEHAVIOR
     SoGLRenderAction
          Draws lines based on the current coordinates, normals, materials,
          drawing style, and so on.

     SoRayPickAction
          Picks lines based on the current coordinates and transformation.
          Details about the intersection are returned in an SoLineDetail.

     SoGetBoundingBoxAction
          Computes the bounding box that encloses all vertices of the line set
          with the current transformation applied to them. Sets the center to
          the average of the coordinates of all vertices.

     SoCallbackAction
          If any line segment callbacks are registered with the action, they
          will be invoked for each successive segment in the line set.
