These functions are arguably unnecessary; they're only used in views_examples.
It's plausible that some textfield control (omnibox?) may want to set the font
weight, but it's tough to defend adding functionality with no imminent need. I'm
not really opposed to adding these, but you'll need to add unit tests.
