ArrangementBasicTraits_2::Compare_y_at_x_2

Comparison_result fo ( ArrTraits::X_monotone_curve_2 xc1 , ArrTraits::X_monotone_curve_2 xc2 , Curve_end ce )
returns SMALLER, EQUAL or LARGER according to the y-ordering of the two curves xc1 and xc2 at x = - (if ce is MIN_END) or at x = (if ce is MAX_END), with the precondition that both curves have unbounded minimal (or maximal) ends that lie at x = ± .
