1.43 class curve_point

A curve_point is a point of a path that is reached by a Bezier curve from the previous point. With one control point (curve_point<-control2 is @nil) the curve is quadratic, with two it is cubic. The control points are in the same coordinate system as the points of the path and are moved and scaled with them.
