This permits to make evidence that we have some bad object passing on various code parts. I fixed majority of them to reduce the scope of passed objects
Unfortunately, for some edge cases i should have to expose ISceneManager from client, this should be fixed in the future when our POO will be cleaner client side (we have a mix of rendering and processing in majority of the client objects, it works but it's not clean)
The inventory image size of the inventory image of nodes with drawtype allfaces (and related) is scaled as well if visual_scale is set (previously, the inventory image size was always the same)
