While fighting jetlag last night, I realised you will also need to check the
Ash-on-Windows8 case - pretty sure it will come up. Profile switching does not
work there, so we shouldn't show the profile selector (see e.g.
http://crbug.com/229704 ). You'll need a runtime check for desktop type
according to the app list window. Maybe here via a delegate interface, or
possibly (maybe nicer) in c/b/ui/app_list/app_list_view_delegate.cc simply by
putting only the active user in the model, in PopulateUsers. But then (since
they *are* a multi-profile user), we might want to show which profile is active,
but first cut could be to just rely on the ash system tray indicating the active
profile (assuming that's still a thing on Windows8).
