D1uIsNull : ||D1U|| <= Resolution.
D1vIsNull : ||D1V|| <= Resolution
D1IsNull : the first derivatives in the U and V parametric directions have null length : ||D1U|| <= Resolution and ||D1V|| <= Resolution
D1uD1vRatioIsNull : the first derivative in the U direction has null length by comparison with the derivative in the V direction ||D1U|| / ||D1V|| <= RealEpsilon
