/* 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.
