      @param aOpeningTab The TabParent that is trying to open this new chrome

      @param aOpener The window which is trying to open this new chrome window.

      @param cancel Return |true| to reject window creation. If true the

                    be created at all. The caller should not default
                    to any possible backup scheme for creating the window.
      @return the new window. Will be null if canceled or an error occurred.
