Adds a conic curve from the current point to x2, y2 with the given weight and x1, y1 as the control point.
All coordinates are given relative to the current point.
This is the relative version of gsk.path_builder.PathBuilder.conicTo.
x offset of control point
y offset of control point
x offset of the end of the curve
y offset of the end of the curve
weight of the curve, must be greater than zero
