Indicates which entities this one should and should not see.
By default only the entities indicated as true by this function
will be shown through the <a href="#Entity.show">show</a> function
and added to the watchlist.
For example, an arrow can see a painting, so Arrow.shouldSee(painting)
will be true, but a painting shouldn't see an arrow, so Painting.shouldSee(arrow)
will be false.
This increases the performances as there are less controls, casts and operation
on arrays in big worlds or chunks of worlds with an high concetration of entities.
