I figure the usefulness of such a library mostly has to do with optimizing (and clipping) refresh in a graphical view port, which is often something the operating system takes care of.

writing operating systems?
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

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.
I just realized I have a user interface project which has been on the back burner for a long time which could really use a library like this. So yes -- I'm interested! Jonathan
