 639 active menubar from a frame, we currently don't take into account mdi-frames
 640 which would ask for menu-merging
 641
 642 Secondly there is no mac api for changing a menubar that is not the current
 643 menubar, so we have to wait for preparing the actual menubar until the
 644 wxMenubar is to be used
 645
 646 We can in subsequent versions use MacInstallMenuBar to provide some sort of
 647 auto-merge for MDI in case this will be necessary
