Yes, but the whole point of asking <ichael to re-order the markup
was to try to /confirm/ the hypothesis that what he was experiencing
was no more than a rasterisation error.  If


all produce artifacts at the same screen position, we can be
almost certain that it is not the markup that is causing this,
as Michael originally believed, but rasterisation.
