Browse Source 
- Default MPV native log level to "warn" instead of "v" (Linux/Windows),
  add setLogLevel method channel to raise it when debug logging is enabled
- Coalesce MPV render requests via atomic compare_exchange on needs_redraw_
- Clear redraw flag before render so new redraws queue during current frame
