rol,..., anchor. The total number of points should be equal to 3n+1, where n is equal to the number of spline segments. Since <CODE>
GrDrawSplineTo()</CODE>
 uses the current position as the first anchor point, for this function the array should start with the first control point, and there should be 3n points passed.
