Yes -- although I personally do need it even when I do not write
operating systems ;) and thus my question really was if there is any
general interest in such a library, since I did exhaustive searching
and was only able to find such region stuff implemented publicly in the
GDK/GTK library, which is ANSI-C AFAICT, and that led me to the
conclusion that either there is no real use for this stuff outside GUI
kits, windowing systems, and 2D games or efficient region "logic" is
often skipped for ad hoc workarounds like using bounding boxes or
refreshing more than necessary -- in which case there really ought to
be a library.
