NB: This is not a header file, dispite the file name suffix. This file is
included directly into the source code of qcocoawindow_mac.mm and
qcocoapanel_mac.mm to avoid manually doing copy and paste of the exact
same code needed at both places. This solution makes it more difficult
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).
