Exit callback

@d-healey not sure about macOS, but the code I posted will let you remove the window frame. I did it for the installer I was creating before Chris came out with Multipage Creator. Another app where it exists, off the top of my head, is the Windows version of Genelec GLM software.

It's just setUsingNativeTitleBar (false)

@aaronventure Oh I see what you mean. I was referring to the functionality of the stock buttons, but if they can be completely removed then no problem.

@d-healey You can disable the native bar then choose which of the buttons should be shown. This lets them get styled with LAF.

I'm not sure if the ones that remain shown get auto-positioned, if so, it would probably be a good idea to introduce a minimize method which just calls the system function for minimizing, and then for close we can define our own behavior and call quit, and for maximize we can use the new UI rescale method and do all the math for scaling the components manually.
