 // Implementer's note: Moving the window controls is tricky. When altering the
 // code, ensure that:
 // - accessibility hit testing works
 // - the accessibility hierarchy is correct
 // - close/min in the background don't bring the window forward
 // - rollover effects work correctly
 
 // The NSLayoutConstraint class hierarchy only exists in the 10.11 SDK. When
