Hair depenetration is too fast and brutal on SDF

[methusalah]

When the hair is penetrating a SDF mesh, the depenetration causes a high velocity and a big bounce of the strands. It does not happen with sphere boundaries in my tests, with which depenetration is rather slow and linear.

This can happen when the hair is spawn or reset on a character that is not in their original pose (long hair spawned inside the back or shoulders for example).

Is there a way to lower the depenetration speed for SDF collisions?
