Path definition

* A parameterized path is defined like this: * 
   * 'GATEWAY_PARALLEL': {
   *   d: 'm {mx},{my} {e.x0},0 0,{e.x1} {e.x1},0 0,{e.y0} -{e.x1},0 0,{e.y1} ' +
          '-{e.x0},0 0,-{e.y1} -{e.x1},0 0,-{e.y0} {e.x1},0 z',
   *   height: 17.5,
   *   width:  17.5,
   *   heightElements: [2.5, 7.5],
   *   widthElements: [2.5, 7.5]
   * }
   *
*

It's important to specify a correct height and width 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).

*

The 'heightElements' and 'widthElements' 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 heightElement'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. *

* The numbers x0, x1 respectively y0, y1, ... map to the corresponding array index. *

Use case

*

Use case is to scale the content of elements (event, gateways) based * on the element bounding box's size. *

*

Why not transform

*

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.

* * @param {String} pathId The ID of the path. * @param {Object} param

* Example param object scales the path to 60% size of the container (data.width, data.height). *
