* alot of casting. I also only wanted to implement an interface in the
* object it was "released" with IUnknown interface being implemented in the 1 version.
* Of course, with these new interfaces comes the data required to keep the state required
* by these interfaces. So, basically, the pointers contain the data associated with
* a release. If you use the data associated with release 3 in a release 2 object, you'll
* get a run time trap, as that won't have any data.

*
* * The set of interfaces accessible on an object through

* if a call to QueryInterface for a pointer to a specified interface
* succeeds the first time, it must succeed again, and if it fails the
* first time, it must fail on all subsequent queries.
* * It must be symmetric ~W if a client holds a pointer to an interface on
* an object, and queries for that interface, the call must succeed.
* * It must be reflexive ~W if a client holding a pointer to one interface
* queries successfully for another, a query through the obtained pointer
* for the first interface must succeed.
* * It must be transitive ~W if a client holding a pointer to one interface
* queries successfully for a second, and through that pointer queries
* successfully for a third interface, a query for the first interface
* through the pointer for the third interface must succeed.
