code: def rectangle(self, x, y, width, height):

docs: Adds a closed sub-path rectangle
          of the given size to the current path
          at position ``(x, y)`` in user-space coordinates.
  
          This method is logically equivalent to::
  
              context.move_to(x, y)
              context.rel_line_to(width, 0)
              context.rel_line_to(0, height)
              context.rel_line_to(-width, 0)
              context.close_path()
  
          :param x: The X coordinate of the top left corner of the rectangle.
          :param y: The Y coordinate of the top left corner of the rectangle.
          :param width: Width of the rectangle.
          :param height: Height of the rectangle.
