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