For Brian Sperlongano's `americana` renderer to have Canadian highway
shields is 'just' a matter of getting the artwork done.  (There are some
particular requirements for legibility in the vector renderring. It's not
just a matter of copying shield templates over from Wikipedia.)

Of course, if you've been panning through that proof of concept, you'll
notice the places where the renderer falls back on rounded rectangles. That
happens when either the way has a 'ref' but there is no associated route
relation, or else the route relation lacks a network or has a network whose
artwork hasn't been done.  In some areas (e.g. the Niagara-Hamilton-Toronto
corridor or the Richelieu valley) the coverage is nearly complete; in
others, it's nearly nonexistent. The difference in coverage is particularly
striking at the Massachusetts-New Hampshire boundary. (It may have
improved; I haven't re-rendered the tiles in quite a while.)

Obviously, I haven't been intending that rendering to serve as a
general-use map; it's a personal project that's gotten a bit out of hand.
It's unapologetically US-centric, since it draws on a number of Federal and
State data sources apart from OSM.
