Linear Spring?

[fweth]

Is there something like a linear "spring", i.e. a motion value x on which I can do x.set(1) and then it linearly changes to 1 from whatever value they had before? I could use a loop like useAnimationFrame, but my guess is that useSpring stops the internal loop when the spring reaches its rest state, so it should be more performant than letting a loop run forever?
