Doing this from Views seems a bit gross to me.  Opinions about this?

Why? This seems like the right place to me. The other option is to have a type
in window (or in a property on window), which doesn't feel right either.

One more comment here. Are we really going to only have the shadow on menus?
Seems like we would want it normal windows too. That said, I'm sure going that
route would have serious performance implications. Maybe add the ability to turn
it on via a flag?

Yes, they're getting enabled in browser_frame_aura.cc.
