SB collision targets may be picked up from modifier stack
works fine with static targets having subsurf and/or array mofifiers

however when calulating the SB object dynamics the vertices of the
'deform only' m-stack result are used
so SB <-> SB may look strange
subsuf modifier is applied to SB object after doing SB dynamics
(that is: colliding mesh is subsurfed, SB is not )
subsurfed SB cubes colliding

or may give unwanted results

last, modifiers that change vertex locations in time (like waves)
suffer from not beeing seen at needed time resolution
(SBs see colliders static in a frame)
well but that's beyond the limits of the current dep-graph use
and needs to be resolved on design level
anyhoo have fun
