* A method to compute a ray-AABB intersection.
* Original code by Andrew Woo, from "Graphics Gems", Academic Press, 1990
* Optimized code by Pierre Terdiman, 2000 (~20-30% faster on my Celeron 500)
* Epsilon value added by Klaus Hartmann. (discarding it saves a few cycles only)
*
* Hence this version is faster as well as more robust than the original one.
*
* Should work provided:
* 1) the integer representation of 0.0f is 0x00000000
* 2) the sign bit of the float is the most significant one
*
* Report bugs: p.terdiman@codercorner.com
