+.SH DESCRIPTION
+The
+.BR rtgrpblib_draw_quadratic_bezier ()
+function draws onto
+.I raster
+a quadratic Bézier curve, as part of a contour, from
+.RI ( x1 ,
+.IR y1 )
+to
+.RI ( x3 ,
+.IR y3 )
+with
+.RI ( x2 ,
+.IR y2 )
+as the additional control point.
+.PP
+The function draws the linear interpolant of corresponding points in
+the line segments
+.RI ( x1 ,
+.IR y1 )-( x2 ,
+.IR y2 )
+and
+.RI ( x2 ,
+.IR y2 )-( x3 ,
+.IR y3 ).
+
+.SH RETURN VALUES
+None.
