\section{Reverse the Orientation of a Curve.}
\funclabel{s1706}
\begin{minipg1}
  Turn the direction of a curve by reversing the ordering of the
  coefficients.
  The start parameter value of the new curve is the same as the start
  parameter value of the old curve.
  This routine turns the direction of the orginal curve.
  If you want a copy with a turned direction, just make a copy and turn
  the direction of the copy.
