From Andrei:

I attached the first big chunk of changes.
The methods changed are mostly the implementations of  TGeoShape::DistFromInside/DistFromOutside for some specific shapes. The new algorithms are boundary error tolerant, giving the correct distance even if the point is on the wrong side of the boundary. The calling sequence remains un-changed. The affected shapes for now are: box, trd1, trd2, tube, tube seg, cone, cone seg, pcon, pgon. I will complete few remaining for the full description of ALICE next week (para + arb8 family: trap,gtra).
