The fling phase called List::tick_fling itself every 16ms, so on a 120Hz
phone every second frame redrew a position already drawn -- Iris saw the
benchmark scroll visibly less smoothly than her own finger, and it was
the rig rather than the renderer. A real fling is advanced once per frame
by UiData::tick_animations from the frame callback, so the phase now
starts one the way a gesture does (fling + animate) and polls
is_scrolling to know when it settled. ANIM_STEP_MS becomes POLL_MS,
which is what it always was here.
