  Log:
  Bugfix #3493
  
  Replaced sqrt() with the safe version sasqrt() in anisotropic.
  the formula (1 - n*n) should not give negative values for n = dotproduct
  of normals, but float inaccuracy can make negative zeros, as we know!
  
  This solves, hopefully, last annoying "blotches" in hair!
