* Avoid crash in BRepBuilderAPI_GTransform algorithm. The crash in BRepBuilder_Transform has been solved by 0032716. * Move copying modifier to BRepTools package. * Implement copying of triangulation in BRepTools_NurbsConvertModification. * Implement transformation of a triangulation in BRepTools_GTrsfModification. * Update test case bugs/mesh/bug22778 to clean the triangulation after conversion to NURBS (reproduce the same behavior as before).
