#### not a real regression
I think I've hunted a regression, which was none. When closing the application
with `System.exit` the screen gets red, but this isn't caused by my change.
I've even got a fix for it, but it requires changing the lifecycle slightly, by
closing all windows on shutdown. (And some other minor changes to fix some
exceptions)
Runtime.getRuntime().addShutdownHook(new Thread(() -> {
System.out.println("tkExit shutdown hook!");
PlatformImpl.tkExit();
}));
But because this isn't caused by my changes, we can therefore ignore it. But I
had to mention it because I invested too much time into it.
#### toggle
I've readded the toggle code. It's worth mentioning that the code is different
than before.
The original version caused a "beep sound" when closing the window
`[self->nativeFullScreenModeWindow performSelector:@selector(toggleFullScreen:)
withObject:nil];`
The new version doesn't have this problem - but it's also fixing the problem
from the previous version. `[[self->nsView window] toggleFullScreen:self];`
#### exception
With the current version, I also cannot reproduce the problem, with the
exception.
