	//						the team in question is the same as the player, then it should be 
	//						drawn friendly.  If the team is different than the player's, then draw the
	//						appropriate IFF.

	// but that doesn't matter because we return in the statement above here. Below here, color_map needs to be defined
	// which will happen if seen_from_team is valid.
