W.draw bezier arrow(const list& C, int n, color c = window :: fgcol)
draws the bezier curve with control polygon C by a polyline
with n points, the last segment is drawn as an arrow.
W.draw spline arrow(const list& L, int n, color c = window :: fgcol)
draws a spline curve through the points of L. Each segment
is approximated by a polyline with n points. The
last segment is drawn as an arrow.
