Among all the lines moved around, the general idea is quite simple. Actually, there are two ideas implemented there. First one, is when object itself is tagged for update, we tag its point cache component for evaluation, which makes it so point cache is properly reset. We do it implicitly because otherwise we'll need to go everywhere and add explicit tag in almost all the properties. Second thing is, we link all collider and force fields to a point cache component using special type of link. This type of link only allows flush if change is caused by a user update. This way reset does not happen when change is caused due to animation, but will properly happen when user causes indirect change to the objects which are part of physics simulation.
