Try to detect player traces going through a change in fluid medium
such as water/air or water/glass, and block facial recognition
through it.
Specifically allow air-into-glass transitions, or into any other
medium otherwise clear enough to allow sunlight to propagate.
Attempt to place stack node directly when player is pointing at
a node space, instead of tossing out an item ent.
This makes item organization less tedious in the early game, as
players are manipulating node positions instead of calculating
ent ballistics in their heads when trying to lay out inventories
on the ground, or using naive shelving.
(Note that wooden shelves still have an advantage in how quickly
items can be taken from them).
Items are still tossed as ents if a player is not looking at a
valid place in nodespace, so inventories can still be e.g. thrown
over a cliff or jettisoned in the ocean...
Use interception where possible to modify destintion for items
directly instead of relying on post-hoc inventory rearrangement.
This should resolve the glitches where items appear in the wrong
place in inventory for a flash before being moved.
