[Bf-committers] point cache

Regarding 'resume' feature: That's working perfectly here since I do the 
same as he does for particles. Even if it is namen 'pointcache' I also 
use it to save all essential states/variables which could not be 
calculated otherwise and are a result of an accumulated calculation 
(like velocity, position and constrained position). So at least until I 
have a second order integration system, it should work.
I don't even think that it's a "bad usage" of pointcache since we 
discussed during the physics sprint that we can save whatever we want in 

I also think that the depsgraph is pretty nice working when used 
correctly, BUT there are too many situations where dynamics have no idea 
what's going on "out there". That's why particles/softbodies/cloth needs 
lots of flags out there to "see" when a relevant change has happened 
(painting on used weight map, changed geometry, rotate/scale/grab, ...).

But that's what the others have already said, so..... ;-)
