26  * Class representing a backend that essentially represents another backend, the

28  * differs from static objects in that it allows you to instantiate an instance
29  * of the object. (The frontend differs in that it scales the object to a specific
30  * size). The icon also does not allow the selectable property; they are always
31  * selectable.
