Computed font stack

[devin....@gmail.com]

If I inspect an area of text and look at the computed font-family,
it'll show something like "Arial, Helvetica, sans-serif". Is it
possible to show only the font that's actually getting rendered,
rather than just the value of the font-family attribute? Maybe it's
not even possible to find out which font the browser ends up using,
but it would be helpful.

Yes, this is the key question, otherwise the implementation would be
simple.
If you found a suitable moz API, please let us know in the bug.
