    Hi Martin,

    (and thanks for making points that are relevant to the subject; I really
    wish people would change the subject line when they change the
    topic)

    Acutally, the tab stops, AFAIR, are only handled using layout units,
    and fp_Line::layout() too works in layout units, and so does the
    fb_LineBreaker class.

    But you are quite right, we have to fix the way that we obtain our font
    metrics first; I will examine the code later today to see what exactly
    would be involved if we only used high-resolution units.
