// This is a WORKAROUND for a quirk in Bullet: due to floating point error slow spinning kinematic objects will
// have a measured angular velocity of zero. This probably isn't a bug that the Bullet team is interested in
// fixing since there is one very simple workaround: use double-precision math for the physics simulation.
// We're not ready migrate to double-precision yet so we explicitly work around it by slamming the RigidBody's
// angular velocity with the value in the entity.
