FCPXML writes point markers as one frame at the sequence rate. Import
compared duration to 1 tick, so a 24fps one-frame marker became a
range. Treat duration ≤ one sequence frame as a FilmCraft point.
Exact rational time strings, formats/assets/media/effect resources, library/event/project,
spine with asset-clip/clip/ref-clip/gap/transition, connected clips and secondary storylines
by lane, srcEnable audio/video merge, timeMap constant speed/reverse/freeze, adjust-transform/
blend/volume with keyframes, markers and chapter markers. Golden document and round trips.
