Arguments: box &optional position-to-return
Returns the position which is the center of the left edge of
box, rounding down if necessary. If
position-to-return is supplied and non-nil
, it must be a position object (see make-position). In that
case, position-to-return is returned, after being
modified to be the right center of box. If
position-to-return is nil
, a new position object is returned.
See the description of the box
class for general information on boxes.
