 439 active menubar from a frame, we currently don't take into account mdi-frames
 440 which would ask for menu-merging
 441
 442 Secondly there is no mac api for changing a menubar that is not the current
 443 menubar, so we have to wait for preparing the actual menubar until the
 444 wxMenubar is to be used

 446 We can in subsequent versions use MacInstallMenuBar to provide some sort of
 447 auto-merge for MDI in case this will be necessary
