Description
When a rigid particle is frozen by contact with an unready volume, this is the number of frames which it will remain frozen after losing contact. Theoretically it could be zero, but chaos can take 1-2 frames to fully initialize the collision of new particles, and so we default it to 2 to be safe. Please avoid the temptation to use this as an indefinitely extendable \"freeze timer\" to cover up more serious timing issues in systems which use readiness.
