 521 Mac Implementation note :
 522
 523 The Mac has only one global menubar, so we attempt to install the currently
 524 active menubar from a frame, we currently don't take into account mdi-frames
 525 which would ask for menu-merging
 526
 527 Secondly there is no mac api for changing a menubar that is not the current
 528 menubar, so we have to wait for preparing the actual menubar until the
 529 wxMenubar is to be used
 530
 531 We can in subsequent versions use MacInstallMenuBar to provide some sort of
 532 auto-merge for MDI in case this will be necessary
