 I don't know how to get the size of the menubar under Mac but I can
confirm that wxDisplay::GetClientArea() should definitely account for it
and it doesn't do it now which is certainly a bug. Stefan, if you have time
to look at this, please add GetClientArea() implementation to
wxDisplayImplMacOSX class. Otherwise any pointers to Mac API which allows
to get the size of the client area (i.e. excluding the menubar) would be
welcome.

 Thanks,
