Rolling friction limit

[TrianglesPCT]

In the sequential impulse solver(btSequentialImpulseConstraintSolver.cpp) I noticed the rolling limit is set like this:

btScalar rollingFrictionMagnitude = rollingFrictionConstraint.m_friction * totalImpulse;
if (rollingFrictionMagnitude > rollingFrictionConstraint.m_friction)
	rollingFrictionMagnitude = rollingFrictionConstraint.m_friction;

This seems odd to me, it is basically clamping totalImpulse to never be greater than 1..

Does anyone know if this is correct or what the reason for this is?

I tried removing it and it doesn't appear to break anything, although rolling frictions effect on the simulation seems pretty small overall so maybe I'm just not noticing.

Thanks

I inspected btMultiBodyContraintSolvers.cpp version of rolling friction and indeed it does not do this clamping, so I guess I'll just go ahead and remove it from my copy
