bounding box, if I understood correctly is a box that frames the box in which we work. It allows to align the box on the left, on the right, in the center.
Its use can be found in LaTeX package like
tcolorbox and certainly in other LaTeX packages as well as in the
Adobe Post Script reference manual.
We do not find this notion, except error of my part in
LaTeX2e written by L. Lamport.
From the historical point of view who (or what computer language) introduced this notion?
Is the concept of bounding box equivalent in all LaTeX packages? in all languages?
