Hi (Janek),

do you think it would be possible for the 2d metaengines to not accept
both combinations of types, but only one? To put it straight: facet
(/box etc) and sphere can create two interactions, with

 1. id1=Facet, id2=Sphere
 2. id1=Sphere, id2=Facet

For the case 1., IFacet2IS4SCG::go is called, which is just fine.
However, for the second case, we call goReverse, which in turn calls
::go and then swaps a some variables. The swapping happens at _every
iteration_.

My point, therefore, would be to mandate type order for 2d metaengines
-- the collider could, when creating new the interaction, swap ids
easily, so that they would be always in the order expected by the
metaengine. Or - perhaps better, since collider knows nothing about
types, swap them in the MetaEngine

I am currently experimenting with swapping the order in the
EngineUnit::goReverse, I will see what the results are.
