Replace the incorrect implementation of Axis Aligned Bounding Boxes transformation to Jim Arvo's efficient AABB transformation algorithm described in his chapter in the Graphics Gems (1990) book.
The algorithm simplifies the number of operations necessary to transform the AABB. Instead of transforming the eight vertices of the original AABB, and then computing the bounding box of the transformed vertices, Arvo's algorithm works by forming both products for each component of the min and max point, and summing the smallest/largest terms, we arrive at the minimal/maximal value.
