In the functions quakelib::ModelWorld::min_bound and quakelib::ModelWorld::max_bound (QuakeLibIO.cpp) bounds are checked using only the 3 vertices specified for an element. However, quad elements have an implicit 4th vertex that can be derived from the other 3. This vertex should be included in the bounds checking.
