  14 //  per-top-level-window logic and data, to handle such things as IME
  15 //  commit when the window gains/loses focus. We can't use a window
  16 //  delegate, because an embeddor probably already has one. Nor can we
  17 //  subclass NSWindow, again because we can't impose that burden on the
  18 //  embeddor.
  19 //

  21 //  up TopLevelWindowData as a notification observer etc.
