 535 Mac Implementation note :
 536
 537 The Mac has only one global menubar, so we attempt to install the currently
 538 active menubar from a frame, we currently don't take into account mdi-frames
 539 which would ask for menu-merging
 540
 541 Secondly there is no mac api for changing a menubar that is not the current
 542 menubar, so we have to wait for preparing the actual menubar until the
 543 wxMenubar is to be used
 544
 545 We can in subsequent versions use MacInstallMenuBar to provide some sort of
 546 auto-merge for MDI in case this will be necessary
