* Usage notes:
This component has an |activeWindow| property. Clients may expect
this property to be always current, so to properly integrate this component
the application will need to keep it current by setting the property
as the active window changes.
This component does automatically keep an accurate list of extant
windows; windows need not be added or removed by hand (and there's no
interface for doing so).
Windows referenced will not be refcounted; the implementation will
claim no ownership. Since it's the nature of this service to always
hold a ("weak") reference to an open window, this requirement removes
a potential reference loop. It should be safe because it's a
design requirement that clients explicitly maintain |activeWindow|,
and that windows remove themselves from the service when they are closed.

* This component should not keep a (XPCOM) reference to any windows;
* the implementation will claim no ownership. Windows must notify
* this component when they are created or destroyed, so only a weak
* reference is kept. Note that there is no interface for such notifications
* (not a public one, anyway). This is taken care of both in Mozilla and
* by common embedding code. Embedding clients need do nothing special
* about that requirement.
* This component must be initialized at application startup by calling
* setWindowCreator.
