 539 Mac Implementation note :
 540
 541 The Mac has only one global menubar, so we attempt to install the currently
 542 active menubar from a frame, we currently don't take into account mdi-frames
 543 which would ask for menu-merging
 544
 545 Secondly there is no mac api for changing a menubar that is not the current
 546 menubar, so we have to wait for preparing the actual menubar until the
 547 wxMenubar is to be used
 548
 549 We can in subsequent versions use MacInstallMenuBar to provide some sort of
 550 auto-merge for MDI in case this will be necessary
