[css3-animations][bug-14795] Resolution of keyframe selectors outside [0%-100%]

Looking into this open issue [1], I find that both Firefox (Aurora) and IE10
ignore keyframe selectors that are <0% or >100% and simply run the animation
as if they weren't present.

WebKit (Chrome 21) seems to ignore the entire animation of any keyframe selector
is out of bounds.

(I have no build of Opera that supports css3-animations at the moment).

I propose we specify the behavior implemented by Firefox and IE; it seems more
consistent with author expectations of what would happen to an invalid selector.
