Adds a cubic Bézier curve from the current point to x3, y3 with x1, y1 and x2, y2 as the control points.
All coordinates are given relative to the current point.
This is the relative version of gsk.path_builder.PathBuilder.cubicTo.
x offset of first control point
y offset of first control point
x offset of second control point
y offset of second control point
x offset of the end of the curve
