Tweak knife/unwrap tesselation code a bit, it uses a random offset, now also
seed the random number generator to at least make these operator repeatable.
I don't know why it is using random numbers at all, we should really not be
doing this in my opinion, but I don't understand why it's being done so won't
remove it.
