// nsGlobalWindow inherits PRCList for maintaining a list of all inner
// windows still in memory for any given outer window. This list is
// needed to ensure that mOuterWindow doesn't end up dangling. The
// nature of PRCList means that the window itself is always in the
// list, and an outer window's list will also contain all inner window
// objects that are still in memory (and in reality all inner window
// object's lists also contain its outer and all other inner windows
// belonging to the same outer window, but that's an unimportant
// side effect of inheriting PRCList).
// NB: Currently nsPIDOMWindowInner and nsPIDOMWindowOuter are identical classes
// with identical member variables and identical vtables, that only differ in
// type name. nsGlobalWindow doesn't want to doubly inherit (and have two
// copies of everything), and it also doesn't want to privilege one over
// the other by making it possible to convert types through the C++ type system
// instead of our accessor methods (AsInner and AsOuter) that do dynamic
// checking. So we inherit from nsPIDOMWindow<nsISupports>, which is also
// identical to both nsPIDOMWindowInner and nsPIDOMWindowOuter, but not
// convertible to either.

* aOptions, but without affecting any other window
* features.
*
