Perhaps there is a misunderstanding.  AFAIU, you can determine the
left-top pixel position at point, but you wanted the left-bottom
position instead, is that right?  If so, my suggestion was to call
vertical-motion to move down one line, then take the left-top position
at that place.  Doesn't that give you what you want?
