- (Wrapper generators): Add comment about the 30-90% figure. - Reword `Pointers' to be shorter/clearer. - Promote `Optimizing Type Translators' to a full section, a few other things here, most conspicuously expanding on the note about expand-* method definition time. - (Tutorial-Conclusion): Not a first draft anymore. - Document convert-to-foreign, convert-from-foreign, and free-converted-object.
