Defining them in the UI definition file was buggy in Unity
and MATE (Mutiny layout). Somehow creating them manually
via the API works around that bug.
The only problem is that Unity fails to update the
marker for the active menu item on the *first* click.
It then lags one item update behind, i.e.
1) CGB is active
2) Click on AGB, CGB is still rendered as active
3) Click on any (including AGB) of the options, now AGB is rendered as active
Also: The Gnome 3 style hamburger menu has been removed.
Also we now fall back to SDL_GameControllerRumble if a controller
doesn’t support the haptic feedback API.
This still poses problems with the WUP-028 but for now cou can disable
rumble completely if you want to use this controller adapter.
