/**
* Contains a map of path elements
*
* <h1>Path definition</h1>
* A parameterized path is defined like this:
* <pre>
* 'EVENT_TIMER_WH': {
* d: 'M {mx},{my} l {e.x0},-{e.y0} m -{e.x0},{e.y0} l {e.x1},{e.y1} ',
* height: 17.5,
* width: 17.5,
* heightElements: [2.5, 7.5],
* widthElements: [2.5, 7.5]
* }
* </pre>
* <p>It's important to specify a correct <b>height and width</b> for the path as the scaling
* is based on the ratio between the specified height and width in this object and the
* height and width that is set as scale target (Note x,y coordinates will be scaled with
* individual ratios).</p>
* <p>The '<b>heightElements</b>' and '<b>widthElements</b>' array must contain the values that will be scaled.
* The scaling is based on the computed ratios.
* Coordinates on the y axis should be in the <b>heightElement</b>'s array, they will be scaled using
* the computed ratio coefficient.
* In the parameterized path the scaled values can be accessed through the 'e' object in {} brackets.
* <ul>
* <li>The values for the y axis can be accessed in the path string using {e.y0}, {e.y1}, ....</li>
* <li>The values for the x axis can be accessed in the path string using {e.x0}, {e.x1}, ....</li>
* </ul>
* The numbers x0, x1 respectively y0, y1, ... map to the corresponding array index.
* </p>

* </p>
* <h1>Why not transform</h1>
* <p>Scaling a path with transform() will also scale the stroke and IE does not support
* the option 'non-scaling-stroke' to prevent this.
* Also there are use cases where only some parts of a path should be
* scaled.</p>
*
* @param {String} pathId The ID of the path.
* @param {Object} param <p>
* Example param object scales the path to 60% size of the container (data.width, data.height).
