This interface defines a generic interface for requesting interfaces to which a given object might provide access. It is very similar to QueryInterface found in
nsISupports. The main difference is that interfaces returned from
GetInterfaceare not required to provide a way back to the object implementing this interface. The semantics of QI dictate that given an interface A that you QI on to get to interface B, you must be able to QI on B to get back to A. This interface, however, allows you to obtain an interface C from A that may or most likely will not have the ability to get back to A. This interface is scriptable.
