OK, now I think I understand what you're saying. The unified cache would
still be static though, right? Instead of five 10kb (or 45kb or
whatever) buffers we'd have a single (probably larger, somewhere around
50kb?) buffer used for all fonts, with everything going through the font
cache & LRU code rather than simple static loading.

That does seem like a cleaner, probably faster way of doing things
(faster on the loading side, hopefully reasonably fast wrt individual
glyph access).
