NAME
     rcrv - draws a rational curve

C SPECIFICATION
     void rcrv(geom)
     Coord geom[4][4];

PARAMETERS
     geom   expects the array containing the four control points of the curve
	    segment.

DESCRIPTION
     rcrv draws a rational cubic spline curve segment using the current curve
     basis and curve precision. geom specifies the four control points of the
     curve segment.

     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 rcrv.

     After rcrv executes, the graphics position is undefined.
