Adds a Bezier cubic curve to the receiver’s path from the current point to a new location, which is specified as a relative distance from the current point.
Original signature is '- (void)relativeCurveToPoint:(NSPoint)aPoint controlPoint1:(NSPoint)controlPoint1 controlPoint2:(NSPoint)controlPoint2'
Available in Mac OS X v10.0 and later.

- aPoint (NSPoint)
- The destination point of the curve segment, interpreted as a relative offset from the current point.
- controlPoint1 (NSPoint)
- The point that determines the shape of the curve near the current point, interpreted as a relative offset from the current point.
- controlPoint2 (NSPoint)
- The point that determines the shape of the curve near the destination point, interpreted as a relative offset from the current point.
