The trouble with that approach is when two expanding events (explosions)
meet then you now have one event that is expanding in only one direction.
But you want both events to pass through each other and continue on
in their direction.
Maybe an approach where you cache the results of the most recent check
so if there is nothing that is vulnerable to effect on the square and
nothing on square has changed then use previous result of check. So
you'd know you don't have to check square for anything of interest.
This might has a noticeable effect since some effects such as fireball
have a large number of fireball effects that pass over the same squares
in a short time period.
