Two things made the eyes jump. The body bobbed two units per step and the head
rode along with it, and each eye ran its own random blink timer, so the cat
winked one eye at a time at intervals of its own choosing.
The bob is now a property on the cat rather than an animation owning torso.y,
the amplitude is softer, and the head translates against it by 75 percent, the
way a walking cat keeps its head level. Measured on a 240 px cat, the eye's
vertical travel per step went from 4.0 px to 0.8 px.
Both eyes now share one eyelid, driven by a single timer and a single
animation. That also removes the Behavior that was fighting the blink animation
for the same property, and the mid-blink flicker to the drawn closed-eye arch,
which now only appears when the eyes are really shut.
