 * Adaptive timecode ruler. Tick density follows zoom through

 * at a fifth of the major step when they'd sit at least 8px apart). Click or
 * drag scrubs: the pointer is captured, every move quantizes to a whole frame,
 * and the frame is committed through `onScrub` (the editor routes it to
 * `PlaybackClock.seek`).
