* <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>

| eve.on("mouse", eatIt)(2);
| eve.on("mouse", scream);
| eve.on("mouse", catchIt)(1);

Implementation Summary
1. Enforce API surface and semantic compatibility with 1.9.x branch
2. Improve the module's maintainability by reducing the storage
paths to a single mechanism.
3. Use the same single mechanism to support "private" and "user" data.
4. _Never_ expose "private" data to user code (TODO: Drop _data, _removeData)
5. Avoid exposing implementation details on user objects (eg. expando properties)
6. Provide a clear path for implementation upgrade to WeakMap in 2014
