This restores an old visual scale from the extremely early days
of NodeCore. That style was removed to syncrhonize the scale of
stack nodes with item ents. The syncrhonization can work the
other way, too, though.
This was triggered by wanting to make loose item ents more
visually distinct at a glance from settled stack nodes, by making
loose item ent rotation faster. Since we were going to change the
properties either way, given that, then we might as well use the
better visual.
Since making stack nodes have a full-size collision hull, it was
distracting having the items inside be so mismatched in scale.
Also, the "pointing around stacks" thing becomes less important
in long-run gameplay with shelves in play, which do not allow
pointing around/through anyway.
