RE: frozen value for discrete animation

I thought we had something in there somewhere to make the fill value take
the exclusive endpoint value (as all authors would want, if not expect, and
even if they understand the interval timing model as we do).

I forget where this was, but I remember discussing it. Will hunt around when
I get back online (writing from the train).
