I am not sure what you are asking. I have had this particular division
throw an exception for some font I have installed, but I have no idea
which one at the moment. So if you are implying that font->aveWidth==0
is always true if font->potm->otmTextMetrics.tmHeight==0, that seems not
to be the case.
