- *	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

- *	\param		origin		[in] ray origin
