NAME
          DtPointGetNormalIndex - Gets the list of point normal
          indices for all the points in the given shape and group IDs.


     SYNOPSIS
          #include <Dt.h>


          int DtPointGetNormalIndex( int shapeID, int groupID, int *count, long **indices);


     DESCRIPTION
          DtPointGetNormalIndex() returns a list of point normal
          vertex indices via the pointer to the variable indices given
          the shape number, shapeID, and group number, groupID. The
          total number of indices (the length of the indices array) is
          returned via the pointer to the count parameter.  Each point
          list is terminated by DtEND_OF_FACE (-1). For example, if
          the first group (groupID = 0) of the first shape (shapeID =
          0) has 10 points, the format of the normal index array will
          be:

               1 2 3 4 -1

          were indices 1, 2, 3 and 4 are the point normal indices and
          -1 is the list terminator.  The parameter count will be set
          to 5.

          If no points or normals exist the indices array will be set
          to NULL.  The indices array is an internal buffer.  Do not
          free or modify the index array.


     IMPLEMENTATION
          The AliasAPI implementation of Dt does not support points.
          No point geometry will be returned by this function.


     DIAGNOSTICS
          DtPointGetNormalIndex() returns one on success and zero on
          failure.
