There is now a texture littering problem upon node tree imports: Since property "additional_properties" is imported before "texture_name", an extra texture is generated.
Also, when user changes texture name, the old texture remains (with fake user save mode enabled).
Now additional_properties are imported last, so no extra textures are generated. As for user changing texture names, it is not possible to say if it is intentional or not, so I consider this good as it is now.
