---Purpose: Set the tolerances used by the algorithms:
-- --- Implicit - Parametric
-- --- Parametric - Parametric
-- --- Implicit - Implicit
--
-- TolArc is used to compute the intersections
-- between the restrictions of a surface and a
-- walking line.
--
-- TolTang is used to compute the points on a walking
-- line, and in geometric algorithms.
--
-- Fleche is a parameter used in the walking
-- algorithms to provide small curvatures on a line.
--
-- UVMaxStep is a parameter used in the walking
-- algorithms to compute the distance between to
-- points in their respective parametrtic spaces.
