You'll find a pretty general version written in C which is ALMOST as
good as QuickDraw's regions in the X11 release.  You can find anyone
who claims to be an "X Windows Weenie" and get the sources to

server/include/region.h, server/include/regionstr.h, server/ddx/mi/miregion.c.

That (I think) contains pretty much all you'll need.  There are a few
other .h files that'll contain definitions for things like boxes and
points, but you can mostly figure them out from context.

Hope this helps.
