+ to e.g fix a bug in qcocoawindow_mac.mm, but forget to do the same in
+ qcocoapanel_mac.mm.
+ The reason we need to do copy and paste in the first place, rather than
+ resolve to method overriding, is that QCocoaPanel needs to inherit from
+ NSPanel, while QCocoaWindow needs to inherit NSWindow rather than NSPanel).
