        /* @todo
        Add drag/drop support to specific data props for different series types.

        The dragDrop.draggableX/Y user options on series enable/disable all of these per
        irection unless they are specifically set in options using
        dragDrop.{optionName}. If the prop does not specify an optionName here, it can
        only be enabled/disabled by the user with draggableX/Y.

        Supported options for each prop:
            optionName: User option in series.dragDrop that enables/disables
                dragging this prop.
            axis: Can be 'x' or 'y'. Whether this prop is linked to x or y axis.
            move: Whether or not this prop should be updated when moving points.
            resize: Whether or not to draw a drag handle and allow user to drag and
                update this prop by itself.
            beforeResize: Hook to perform tasks before a resize is made. Gets
                the guide box, the new points values, and the point as args.
            resizeSide: Which side of the guide box to resize when dragging the
                handle. Can be "left", "right", "top", "bottom". Chart.inverted is
                handled automatically. Can also be a function, taking the new point
                values as parameter, as well as the point, and returning a string
                with the side.
            propValidate: Function that takes the prop value and the point as
                arguments, and returns true if the prop value is valid, false if
                not. It is used to prevent e.g. resizing "low" above "high".
            handlePositioner: For resizeable props, return 0,0 in SVG plot coords of
                where to place the dragHandle. Gets point as argument. Should return
                object with x and y properties.
            handleFormatter: For resizeable props, return the path of the drag
                handle as an SVG path array. Gets the point as argument. The handle
                is translated according to handlePositioner.
            handleOptions: Options to merge with the default handle options.

            TODO:
            - It makes sense to have support for resizing the size of bubbles and
                e.g variwide columns. This requires us to support dragging along a
                z-axis, somehow computing a relative value from old to new pixel
                size.
            - Moving maps could be useful, although we would have to compute new
                point.path values in order to do it properly (using SVG translate
                is easier, but won't update the data).
