/* introducing them here, because i know: steps in properties ( at frame timing )

will cause unwanted responses of the softbody system (which does inter frame calculations )
|

so first 'cure' would be: interpolate linear in time ..
|
||||
Q: why do i write this?
|
||||
A: because it happend once, that some eger coder 'streamlined' code to fail.
|
||||
We DO linear interpolation for goals .. and i think we should do on animated properties as well
