 431
 432 The Mac has only one global menubar, so we attempt to install the currently
 433 active menubar from a frame, we currently don't take into account mdi-frames
 434 which would ask for menu-merging
 435
 436 Secondly there is no mac api for changing a menubar that is not the current
 437 menubar, so we have to wait for preparing the actual menubar until the
 438 wxMenubar is to be used
 439
 440 We can in subsequent versions use MacInstallMenuBar to provide some sort of
 441 auto-merge for MDI in case this will be necessary
