Ton Roosendaal 04387f403f 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!
