please add "font previews" (live?)

Its something I have thought of but havent really thought of a good way to do it - it would have to be an image for each font beacuse actually trying to load 500 fonts would be insane, its possible I know, but the problem I have is not so much in building such a thing, its maintaining it - I'll need to think about it, certainly right now I am pretty busy, patches and ideas welcome.

fontyourface is interesting proposition, except that it requires "yet another module", and one thing I have learned over the years is stay away from relying on other-peoples-modules, they have a habit of changing them, despite the attractiveness of leveraging that module I would prefer to stay away from requiring modules. I already did that twice before, and ended up being maintainer of Noggin, and Superfish is too good to replicate in the theme, even though I would actually prefer to load Superfish in the theme (I would get much more control over it).

Sounds more interesting from my perspective to dynamically load a preview, say if you choose a font a bit of text changes to match your chosen font.

Fonts are totally revamped in 7.x-3.x, there is full font-your-face integration (not dependent though, you can use if you want), and Google fonts are done way different. Font-your-face will give you nice previews, but for performance etc and ease of code maintainability this will never happen in the core theme.
