/*
!!mdf-tbd: couple of ideas:

#1 

Allow optionally instanced DamageFilter to support NPCs etc. modifying
their damage filter dynamically -- e.g. shoot NPC, damage it initially
but it "adapts" and after a while no longer hurt by that type of damage (alternatively, 
could just support multiple static filters which are swapped-in but this
wouldn't be as flexible. Could be very cool for boss creatures. Just
add support for instances of DamageFilter (MyDamageFilter) and support
for adding/removing/modifying entries.

#2

Allow damage filter to modify DamageType also (make this an "out" parameter).
e.g. say, shian might react to leeches as though they are burning rather than
causing biological damage.

/*NEW 2002.07.15 PWC
	Added optional out parameter DamageFloat because precision was being lost by using int
	I didn't want to break anyone else's code so I just added an extra parameter which can 
	be used if necessary
