>>> let trigger2 = HumanCmd.TriggerItem{tiverb="verb2", tiobject="object2", tisymbols=[toContentSymbol 'c']}
>>> triggerSymbols [trigger1, trigger2]
"abc"

Check whether one is permitted to aim (for projecting) at a target. The check is stricter for actor targets, assuming the player simply wants to hit a single actor. In order to fine tune trick-shots, e.g., piercing many actors, other aiming modes should be used. Returns a different seps if needed to reach the target.

Note: Simple Perception check is not enough for the check, e.g., because the target actor can be obscured by a glass wall.
