Zoom keyframe

!cue.zoomKeyframe

A keyframe for a graph’s `x-domain` / `y-domain` that announces itself: a box is drawn around the smaller of the two windows, held, and only then does the view move — into the box when zooming in, out of it when zooming out. The box never moves in data coordinates. Everything else works exactly like `!cue.to`, and the two can share a chain.
