While waiting for somebody to go forward with the user interface
design (see 
http://lists.nongnu.org/archive/html/adonthell-artwork/2011-03/msg00000.html),
I'll have a look into this. Aside from the glyph caching, there are
some more things to fix up too:

* The font class is the one remaining piece of GUI code that isn't
properly documented, yet.
* Text rendering isn't part of the normal widget rendering but happens
separately. That means, any highlight or darken effect does not apply
to the actual text, only to the border and background of the text
widget. Same goes for focus overlays, which will actually be rendered
below the text.
