Eliminate special case for closed paths. Just draw caps at both ends and
    accept that the resulting path isn't minimal in all cases. This
    eliminates the weird results from said attempted minimal path with
    large pens and small curves. It also eliminated a lot of extra code
    from this function.
Fix font baseline value (should be 9). Take pen size into account when
    computing positions so that glyphs rest on the baseline instead of
    painting on top of it.
Show baseline in huge text sample
