 544 Mac Implementation note :
 545
 546 The Mac has only one global menubar, so we attempt to install the currently
 547 active menubar from a frame, we currently don't take into account mdi-frames
 548 which would ask for menu-merging
 549
 550 Secondly there is no mac api for changing a menubar that is not the current
 551 menubar, so we have to wait for preparing the actual menubar until the
 552 wxMenubar is to be used
 553
 554 We can in subsequent versions use MacInstallMenuBar to provide some sort of
 555 auto-merge for MDI in case this will be necessary
