/**
* Displays the danger map on the "DangerMap" TileMap. Sums the probable (get to that in a moment) damage the player would
* take from being on the given square on their next turn.
*
* "Danger" is kind of tricky, because the possible danger can be influenced by enemy movement. For example, a railgun shot
* can be intercepted by a scout, rendering all tiles in its path 'safe', but we have no idea if the scout will or won't move
* onto that square. Our current rule is "You can never get hit on a safe square, but can sometimes avoid getting hit on a
* dangerous square." So, we stop a projectile path if it would hit a satellite, but don't stop if it would hit a cruiser,
* even if the cruiser wouldn't have time to move, because it might be destroyed by another projectile and then let the
* projectile pass.
*
* While you could theoretically simulate to the maximum possible fidelity, such that you don't paint it if the cruiser has
* HP than it could possibly take in a round and do if it doesn't, that doesn't seem worth it.
