/* The COM interface for upversioning an interface
* We've been given a GUID (riid) and we need to replace the present
* interface with that of the requested interface.
*
* Snip from some Microsoft document:
* There are four requirements for implementations of QueryInterface (In these
* cases, "must succeed" means "must succeed barring catastrophic failure."):
*
* * The set of interfaces accessible on an object through
* IUnknown::QueryInterface must be static, not dynamic. This means that
* 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.
*
* As you can see, this interface doesn't qualify but will most likely
* be good enough for the time being.
