* Extends and replaces default nodes renderer and implements square shaped nodes.
* <p>
* By specifically extending a preview default renderer, this replaces it and the old one is no longer available.
* A default renderer can be extended in order to add more features to it, or simply replace it completely.
* Default renderers are contained in <code>org.gephi.preview.plugin.renderers</code> package.
* <p>
* Note that we need to set the position parameter even this replaces other renderer.
* In this case and normally, the position has been set the same that the replaced renderer has (300).
