* The Polyline2D and Polyline3D Explode method will preserve the smooth type.
* Deleted the references to the ImageDefinitionReactor from the ImageDefinition they will be created when the DXF is saved.
* (fixed) Issues, introduced in the last two updates, when saving Polyline2D, Polyline3D, and PolyfaceMesh entities that were part of a Block.
