Paint.CurveTo (gb.qt4)
Static Sub CurveTo ( X1 As Float, Y1 As Float, X2 As Float, Y2 As Float, X3 As Float, Y3 As Float )
Adds a cubic Bézier spline to the path from the current point to position (X3, Y3) in userspace coordinates, using (X1, Y1) and (X2, Y2) as the control points. After this call the current point will be (X3, Y3).

X1 : the X coordinate of the first control point.

Y1 : the Y coordinate of the first control point.

X2 : the X coordinate of the second control point.

Y2 : the Y coordinate of the second control point.

X3 : the X coordinate of the end of the curve.

Y3 : the Y coordinate of the end of the curve.
If there is no current point before the call to Paint.CurveTo this function will behave as if preceded by a call to Paint.MoveTo(X1, Y1).
