NAME
	  DtShapeGetNormals - Get a list of normals for	the given
	  shape.


     SYNOPSIS
	  #include <Dt.h>


	  int  DtShapeGetNormals( int shapeID, int *count, DtVec3f **normals )


     DESCRIPTION
	  DtShapeGetNormals() returns a	normal list for	the shape
	  indicated by the given shapeID. The number of	normals	is
	  returned in count. A read-only pointer to a list of the
	  normals is placed in the variable pointed to by normals.
	  This array is	an internal buffer.  Do	not free or modify the
	  normal array.	 C programmers can access the components of
	  the normal array as though it	were a simple structure	as
	  follows:

		    typedef struct DtVec3f { float vec[3];};

		    DtVec3f *norms;
		    DtShapeGetNormals( shapeID,	DtVec3f	&norms );
		    /* The first normal	*/
		    x =	norms[0].vec[0];
		    y =	norms[0].vec[1];
		    z =	norms[0].vec[2];



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