pkv 571d2d532b 0026619: Tolerances of operands are modified using bop
The fix forces creation of new sub-shapes (vertex, edge) when the tolerance of some sub-shape of an argument is to be increased.

This new behavior is turned off by default. It can be turned on using two ways:
1) Setting 'locking' flag of the arguments.
2) Calling the method SetNonDestructive(Standard_True) of the class BOPAlgo_PaveFiller.
