Detailed Description

This is only used if use_scaling is true. After the scaling is done, we
also scale the objective by a constant factor. This is important because
scaling the cost has a direct influence on the meaning of the
dual_feasibility_tolerance. Because we usually use a fixed tolerance, the
objective must be well scaled to make sense.
