    Of course, and it was useful because there was new media and a fully
    different technology.

    With "kerning", there already is an existing concept of kerning for
    digital fonts, and it does not include anchor-based positioning.
    Philippe is proposing an extension of the term but this has the
    potential of confusion because the same term can mean two different
    things in the _same_ medium.

    When your father hand-set type 72 points was 0.9958 inches in the U.S.
    and 1,0657 inches in Europe, and this is why the points were called
    "Pica points" in the U.S. and "Didot points" in Europe for clarification.

    If Philippe wants to add some clarifying adjective to his use of the
    term "kerning" (e.g. Philippean kerning), no objection to that. But I'd
    rather he did not hijack the general term for his own definition.
