Bitmasks are used in InteractionGeometryDispatcher; if (mask1 &
mask2)==0 and the masks are not zero (IIRC), then the bodies will not
enter interaction. (I will document it properly in the doc I am writing,
but that will take some time).

The same could be done here, one bitmask for the functor, another for
the body.
