Hmm, I found the solution. Change the value of epsilon1 from 0.001 to
1.0. I don't know why, but it fixes the distortion and makes the
distribution completely even. :)

As I assumed, it was something with how the w value was calculated.
Apparently, if 1-2*u*v is smaller than 1.0, then no division should
happen at all (or a division by 1). I found out by coincidence more or
less, so don't ask me why...
