I do think the `font-lock-face' interface is quite a bit easier to use. 
The other alternative is Miles' suggestion of having font-lock toggle
display of `face' properties.

Right; I'll change that to `turn-on-font-lock'.  Thanks.

Because the user can specify their own rules for fontifying buffers
using `ibuffer-fontification-alist'.  The number of rules (and therefore
faces) is unbounded, so I need a separate category for each rule. 
Unless there's something I'm missing...

Ahhh...yes, I see a way to do it by just referencing back into
`font-lock-category-alist'.  Still just a little bit more complex than
I'd like, but it works.  Thanks.
