Limit for Normalise() call was 0.000000001 or so. This is still far too
big, since a float can go to 10^-37. And, this value is still squared, so
a square root will not frustrate it.
Limit now is 10^-35, fixing disappearing faces in extreme small object
thats extreme close to a camera. (thanks OOPz!)
