libopenshot/tests/Timeline.cpp
Jonathan Thomas 4387f8b394 - Timeline composition no longer mutates cached clip frames (fixes trails/ghosting). 
- Clip updates via ApplyJsonDiff now also clear clip cache (not just timeline/reader ranges).
- Added regressions for cache invalidation + no cached-frame mutation; kept paused preroll/cache-bar behavior intact.
