Subject: [PATCH] replace exit() by throw sg_exception(). Of course, we have to
 be aware that interdependencies between sg libs are generally unwelcome, but
 sg_exception is a rather basic part, and it's already used by xml, props,
 scene, sound and, of course, structure. Since props and xml are core libs, we
 can assume that sg_exceptions are available.  (OK'ed by Curt)
