so, if i just do this to asign a new texture to an object
stateset.get()->setTextureAttributeAndModes(1, new_texture.get()
,osg::StateAttribute::ON);
in case that there is already a number one texture will the OSG free the
previous texture and it´s image before replacing it with the new one???
every textures are ref_ptr of course
thanks
