NAME
     crv - draws a curve

C SPECIFICATION
     void crv(points)
     Coord points[4][3];

PARAMETERS
     points    expects an array containing the four points that define the
	       curve. The routine expects 3-D points (x, y, and z coordinates
	       for each point).

DESCRIPTION
     crv draws a cubic spline curve segment (defined by the four submitted
     points) according to the current curve basis and precision.

     The curve segment is approximated by a sequence of straight lines.	 All
     lines use the current linestyle, which is reset prior to the first line
     and continues through subsequent lines.  Other line modes, including
     depthcueing, line width, and line antialiasing, also apply to the lines
     generated by crv.

     After crv executes, the graphics position is undefined.
