Supporting the Mac OS menubar in JavaFX

I guess I was just referring to the various menus that an application 
may want to describe to the system on the various platforms, not 
everything to do with platform integration.  Aren't there just a small 
number of those?

Window-specific menubar (wherever it appears)
Application-general menubar (only appears on platforms that have 
separate system menubar that survives last window closing)
App dock icon (system tray?) context menu
(A couple more possible context menus?)

Where do we want the data to live where (as in, which object and what 
method) the app can specify other context menu items to install for its 
dock icon?  Does that decision affect where (object/method) we might 
want the various other (window-specific and app-general) main menus to 
be installed?

I don't think those are huge questions, but let's get a reasonably full 
list of all of the various menus (and possibly keyboard shortcut hooks?) 
that may need to be available on the various platforms and we will 
probably have a pretty decent confidence that we've come up with a good 
plan on where to locate the Mac-focused menubar APIs...
