	// One drawback of the new shooting mechanism is that it depends on the the JSD files being accurate.  These
	// files determine how an obstruction (like an enemy soldier) takes up space in a 3D tile.  This is done by
	// splitting a tile into 125 "cubes", stacked 5 x 5 x 5.  Each "cube" is 2 units wide, 2 units deep and about
	// 6 units tall.  A standing merc in the JSD files is represented by a "plus sign" shaped construct that is
	// 3 "cubes" tall, 3 "cubes" wide and 1 "cube" deep.  A crouching soldier is 2 x 3 x 2 and a prone soldier is
	// 1 x 3 x 5.  This means if we're shooting at a standing target from the side, we effectively have 1/3 the
	// chance to hit as we would a target that was facing us.  Unfortunately, the graphical cursor can't display
	// this information so it will appear as though you have the same chance of hitting regardless of the targets
	// facing.
	//
	// As a result of the above, this function determines the targets facing compared to the shooters, and will
	// reduce the Shot Offsets if the target isn't facing directly towards or away from the shooter.  This isn't
	// the most accurate solution but it's the best solution I can come up with at this time.  The alternative is
	// to let shots that appear to have no chance of missing (shooting aperture within the targets displayed body)
	// actually miss an average of 2 in every 3 shots.
	//
	// I'm going to assume for the moment that the 1/3rd chance only occurs when a target is facing directly perpendicular
	// to your facing.  I don't know for sure if this is true or not, but it's the assumption I'm going to make.
