NAME
	  glNormal3b, glNormal3d, glNormal3f, glNormal3i, glNormal3s,
	  glNormal3bv, glNormal3dv, glNormal3fv, glNormal3iv,
	  glNormal3sv -	set the	current	normal vector


     C SPECIFICATION
	  void glNormal3b( GLbyte nx,
			   GLbyte ny,
			   GLbyte nz )
	  void glNormal3d( GLdouble nx,
			   GLdouble ny,
			   GLdouble nz )
	  void glNormal3f( GLfloat nx,
			   GLfloat ny,
			   GLfloat nz )
	  void glNormal3i( GLint nx,
			   GLint ny,
			   GLint nz )
	  void glNormal3s( GLshort nx,
			   GLshort ny,
			   GLshort nz )


     PARAMETERS
	  nx, ny, nz
		    Specify the	x, y, and z coordinates	of the new
		    current normal.  The initial value of the current
		    normal is the unit vector, (0, 0, 1).

     C SPECIFICATION
	  void glNormal3bv( const GLbyte *v )
	  void glNormal3dv( const GLdouble *v )
	  void glNormal3fv( const GLfloat *v )
	  void glNormal3iv( const GLint	*v )
	  void glNormal3sv( const GLshort *v )


     PARAMETERS
	  v    Specifies a pointer to an array of three	elements:  the
	       x, y, and z coordinates of the new current normal.

     DESCRIPTION
	  The current normal is	set to the given coordinates whenever
	  glNormal is issued.  Byte, short, or integer arguments are
	  converted to floating-point format with a linear mapping
	  that maps the	most positive representable integer value to
	  1.0, and the most negative representable integer value to
	  -1.0.

	  Normals specified with glNormal need not have	unit length.
	  If normalization is enabled, then normals specified with
	  glNormal are normalized after	transformation.	 To enable and
	  disable normalization, call glEnable and glDisable with the
	  argument GL_NORMALIZE.  Normalization	is initially disabled.

     NOTES
	  The current normal can be updated at any time.  In
	  particular, glNormal can be called between a call to glBegin
	  and the corresponding	call to	glEnd.

     ASSOCIATED	GETS
	  glGet	with argument GL_CURRENT_NORMAL
	  glIsEnabled with argument GL_NORMALIZE
