[Math formula] find closest point to ellipsiod

["Mathieu Leclaire" <mleclair(at)hybride.com>]

I'm looking for the fastest formula to find the closest point on the surface
of an ellipsiod. Well actually I only need the distance of the closest point
so if a point has more then one point on the surface that has the same
distance, it doesn't really matter which one, I only need the distance. I'm
browsing through my old Math books but I'm having a hard time finding a
solution so I'm just checking to see if anyone remembers his Math well
enough to guide me towards a formula.
