Right. IIRC, Gerd did not like the caching of glyph matrix elements.
I think he felt that producing the information stored in the glyph is
expensive, and so doing that unnecessarily would hamper performance.
The information my code caches is only relevant to the bidi properties
of the characters, which need to be computed anyway to decide what is
the next character in the visual order.
