I would just prefer to skip addForce() when the shape is not a sphere. But
it needs to be tested before to be sure we will have a benefit from this.

Or, another option, I can add SubscribedBodiesID into the gravityEngine,
like an option, to apply the gravity only to subscribed bodies to escape
loop over facets.

What do you think?
