Yeah, of what use is a sequence of Unicode characters in visual order? 
The whole point of a shaping engine is to convert characters to glyphs 
and in the proper order, right?

And for documentation, I feel you should read the Graphite 
documentation. Even though it is not OpenType, it should be quite 
instructive as to rendering in general as it throws the entire 
responsibility of rendering on the font programmer.
