- Ensure that the subshapes from the original shape will not be changed after nurbsconvert operation. For that create the new vertexes (NewPoint(..)) as well as new curves (NewCurve(..)) and new surfaces (NewSurface(..)) before calling of Rebuild() method. Make copies of all vertexes impacted by curve or surface modifications. This eliminates necessity of creation of new vertices during recursive rebuilding of the entire shape. - Compatibility with the old behavior of BRepTools_Modifier has been retained as an option. For that the new flag MutableInput has been added in the interface of the class. - This patch also impacts other operations based on BRepTools_Modifier, in the sense that they also become safe regarding input shapes. - Create new test cases. Some test cases with nurbsconvert command are changed to lock input shapes from modifications. fix regressions
