 505 Mac Implementation note :
 506
 507 The Mac has only one global menubar, so we attempt to install the currently
 508 active menubar from a frame, we currently don't take into account mdi-frames
 509 which would ask for menu-merging
 510
 511 Secondly there is no mac api for changing a menubar that is not the current
 512 menubar, so we have to wait for preparing the actual menubar until the
 513 wxMenubar is to be used
 514
 515 We can in subsequent versions use MacInstallMenuBar to provide some sort of
 516 auto-merge for MDI in case this will be necessary
