osc.lua: avoid infinite ticks loop on idle

Before this commit, animation-end was handled at render(), however,
it's not called on idle, which resulted in state.anitype ~= nil, with
nothing to reset it during idle, which caused in an infinite tick()
loop (starts on first mouse move).

Now tick resets the animation on idle, and also, as a safety measure,
if we're past 1s after the animation deadline.

The safety measure is because the osc states are complex, and it's
easier to detect a "we really shouldn't be animating now" at tick()
itself rather than detecting the exact states where animation should
be reset. Generally, the safety mmeasure is not needed.
