    0024429: Cylinder-torus intersection throws an exception and produces no result
    1. The reason of exception has been eliminated.
    2. Interfaces of the following methods have been changed in the classes Contap_TheIWalking and IntPatch_TheIWalking: Perform(...), TestArretPassage(...) and ComputeCloseLine(...).
    Main changes are:
    1. IntWalk_IWalking::TestArretPassage(...).
      a) Anisotropic normalization of 2D-coordinates has been eliminated.
      b) Algorithm of check of validity of WLine has been improved.
    2. IntWalk_IWalking::ComputeCloseLine(...). Check of indices of the sequence of points has been added (to avoid exceptions).

Dear All,

The exception in the intersection algorithm will be fixed in the branch CR29972*. However, the intersection result will be wrong (not closed), see the updated test case in the branch CR24429_1.

The branch CR24429_1 fixes the problem in intersection algorithm completely but leads to many regressions (including overload by CPU-limit). So, it is not ready to be integrated.
