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