What can we do to get this PR moving again?

It looks like the call to `updateSceneState` is necessary. The scene state is tracking the iconified state of the window and needs to be update when the window leaves the iconified state (so `updateSceneState` should also be called when the window is maximized). Personally I think the EventHandler should also call `entireSceneNeedsRepaint`; it's the core code that stopped drawing to the window when it became iconified and so it should be the core that ask for a repaint when the window is de-iconified. But I would also be happy to update the Mac glass code to call `notifyRepaint` to match Windows and Linux.
