def measure(available_width)
  @x2 = Style.dimension(style(:x2), available_width).to_i
  @y2 = Style.dimension(style(:y2), available_width).to_i
  @width = (@x2 - left).abs
  @height = (@y2 - top).abs
end

#paint(painter, ox, oy) ⇒ Object

A line's endpoints are both slot coordinates, so it cannot use the usual "draw at my top-left" convention.
