Changing a Line's center y-value will cause the Line's frame to change.

[Ollstar]

Creates line:

    //create the end points for a line
    let endPoints = [Point(), Point(self.canvas.width, 0)]

    //create the line and center it
    line = Line(endPoints)
    line.center.y = self.canvas.center.y

This changes the Line's frame's width from 736 to 100 which is not expected.
