/**

* nsIWindowWatcher is the keeper of Gecko/DOM Windows. It maintains
|
|
* a list of open top-level windows, and allows some operations on them.
|
|
|
|
* 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 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.
