+ * or the provider does not provide a window, the window watcher will proceed
+ * to actually open a new window.

+  /**
+   * A method to request that this provider provide a window.  The window
+   * returned need not to have the right name or parent set on it; setting
+   * those is the caller's responsibility.  The provider can always return null
+   * to have the caller create a brand-new window.
+   *
+   * @param aParent Must not be null.  This is the window that the caller wants
+   *        to use as the parent for the new window.  Generally,
+   *        nsIWindowProvider implementors can expect to be somehow related to
+   *        aParent; the relationship may depend on the nsIWindowProvider
+   *        implementation.
+   *
+   * @param aChromeFlags The chrome flags the caller will use to create a new
+   *        window if this provider returns null.  See nsIWebBrowserChrome for
+   *        the possible values of this field.
+   *
+   * @param aPositionSpecified Whether the attempt to create a window is trying
+   *        to specify a position for the new window.
+   *
+   * @param aSizeSpecified Whether the attempt to create a window is trying to
+   *        specify a size for the new window.
+   *
+   * @param aURI The URI to be loaded in the new window (may be NULL).  The
+   *        nsIWindowProvider implementation must not load this URI into the
+   *        window it returns.  This URI is provided solely to help the
+   *        nsIWindowProvider implementation make decisions; the caller will
+   *        handle loading the URI in the window returned if provideWindow
+   *        returns a window.
+   *
+   *        When making decisions based on aURI, note that even when it's not
+   *        null, aURI may not represent all relevant information about the
+   *        load.  For example, the load may have extra load flags, POST data,
+   *        etc.
+   *
+   * @param aName The name of the window being opened.  Setting the name on the
+   *        return value of provideWindow will be handled by the caller; aName
+   *        is provided solely to help the nsIWindowProvider implementation
+   *        make decisions.
+   *
+   * @param aFeatures The feature string for the window being opened.  This may
+   *        be empty.  The nsIWindowProvider implementation is allowed to apply
+   *        the feature string to the window it returns in any way it sees fit.
+   *        See the nsIWindowWatcher interface for details on feature strings.
+   *
+   * @param aWindowIsNew [out] Whether the window being returned was just
+   *        created by the window provider implementation.  This can be used by
+   *        callers to keep track of which windows were opened by the user as
+   *        opposed to being opened programmatically.  This should be set to
+   *        false if the window being returned existed before the
+   *        provideWindow() call.  The value of this out parameter is
+   *        meaningless if provideWindow() returns null.
+
+   * @return A window the caller should use or null if the caller should just
+   *         create a new window.  The returned window may be newly opened by
+   *         the nsIWindowProvider implementation or may be a window that
+   *         already existed.
+   *
+   * @throw NS_ERROR_ABORT if the caller should cease its attempt to open a new
+   *                       window.
+   *
+   * @see nsIWindowWatcher for more information on aFeatures.
+   * @see nsIWebBrowserChrome for more information on aChromeFlags.
