We should resolve the issue raised by dbaron [1] (Bug 14805 [2])

If we have:

	@keyframes timings {
		25% { animation-timing-function: linear; }
		40% { animation-timing-function: ease-out; }	
	}

..then when the animation moves forward we expect linear to apply between 25% and 40%. But if the animation is moving backward e.g. due to an animation-direction: alternate then we also want linear to apply between 40% and 25%. 

Objections?
