Does this mean that, theoretically at least, the bytecodes control the final
output of cleartype fonts down to the pixel level, and that fonts with
complete bytecodes should come out PIXEL PERFECT on linux as they do on
windows (give that dpi is altered to windows' 96dpi)?

Because right now they sure don't, they are extremely different. Will they
one day be pixel verbatim with the windows renderings? Is there some kind of
wiki or documentation for what has been reverse engineered so far, and what
needs to be done (besides the source itself)?
