Discussion

Runs have status that can be used to expedite certain operations. Knowing the direction and ordering of a run’s glyphs can aid in string index analysis, whereas knowing whether the positions reference the identity text matrix can avoid expensive comparisons. This status is provided as a convenience, because this information is not strictly necessary but can be helpful in some circumstances.
