1. Add method TransformPCurves to ShapeUpgrade_UnifySameDomain - to rotate and translate existing pcurves instead of projecting.
2. Modify method ShapeUpgrade_UnifySameDomain::IntUnifyFaces - now it does not apply ShapeFix to new wires and new faces.
3. In the method UnifyEdges: add merging degenerated edges.
- The option SafeInputMode has been added in the class ShapeUpgrade_UnifySameDomain. If it is set then the input shape is protected against modifications of any aspects of its sub-shapes. Default value is true.
- The option "-nosafe" has been added in draw command "unifysamedom". If it is not set the algorithm is run with SafeInputMode switched off.
