initialize_box sets `pxy' to \hpos's contents bounding box. what if
you want pxy to be not strictly a rectangle, but the path that
encloses text, etc., which is just part of flowing text in a paragraph
If I'm not misunderstanding some concepts, bounding boxes are sure to be
rectangles. But why you need `pxy` to not be rectangle. Since you can
get the center and all the four-corner cordinates (and so it's easy to
get the diameter if you want to use it as circles or something like that
latter) of the bounding box, you can construct all kinds of path shapes
if needed.
