Does anything rely on LocationBarDecoration::GetFont()? (i.e. is there a risk
adding SetFont, but not overriding GetFont()). But then I did some `git grep`ing
and it looks like nothing (yet) actually overrides
LocationBarDecoration::GetFont(). (I guess it should probably be non-virtual,
and be called GetDefaultFont() or something)

I like the simplicity of GetFont() in LocationBarDecoration vs. a
GetDefaultFont. Things are only getting messy because I'm adding a SetFont() to
BubbleDecoration but as a result if you call GetFont() on a BubbleDecoration you
may not get the correct answer. I think the best way to fix it is to just
override GetFont() in BubbleDecoration and have it return the correct result.
