/*

Mac Implementation note :

The Mac has only one global menubar, so we attempt to install the currently
active menubar from a frame, we currently don't take into account mdi-frames
which would ask for menu-merging

Secondly there is no mac api for changing a menubar that is not the current
menubar, so we have to wait for preparing the actual menubar until the
wxMenubar is to be used

We can in subsequent versions use MacInstallMenuBar to provide some sort of
auto-merge for MDI in case this will be necessary
