Could parts of ../lisp/textmodes/artist.el be used?

The rectangling feature is usable for setting reasonable rhombus'
At the very least the heuristics of its rubber-banding are already available.

BTW: This would be a _killer-feature_  if the bounding box could be rotated.
Moreso, with key commands e.g. rotate-box-left/right..  :=]

Few image editors do this well if at all (including imagemagick).

elisp certainly has fast enough routines available with `asin' `atan' et al.
If you should happen to find a way to make the box happen please
consider leaving room for rotations - design constraints permitting of

FWIW the ability to rotate/skew boxes in OCR apps is one of the
aspects of that task that is lacking in nearly all commercial products
(the free counterparts all seem to be based on the same legacy HP code
as the commercial derivatives) and it seriously hinders the viability
of the output.

If a bounding box could be implemented as a working part of Emacs
there are some really amazing applications for applying
annotations/text-properties/alist lookups on 'regions' of processed
