[#22884] slow import wavefont/.obj file
- dont run mesh update functions on zero user meshes (a bit of a cheap trick but works well), made in last commit by mistake.
- dont do a scenegraph update on linking an object, run scene.update() after linking objects.
- remove split material option since we have enough slots.
