Hair collision is unstable with little and big boxes

[methusalah]

Hair collision is stable and ok with a 1 meter side cube, but other dimensions does not work well.
On lower dimensions like 10 cm, the hair particles seem to bounce at a high velocity and a lot of particle pass through.
On higher dimensions like 5 m side, the particles does not bounce but slowly sink into the volume.

(I consider 1 world unit as 1 meter)
