Enhance VideoEditor and MotionTracker with improved logging and crop handling

Browse Source 
This commit adds detailed logging to the VideoEditor and MotionTracker classes, providing insights into the transformations and adjustments made during point processing and cropping. It refines the crop position adjustment logic to ensure offsets are only applied when necessary and enhances the visibility of tracking points based on their position relative to the crop area. Additionally, it improves the handling of motion tracking toggling, ensuring a default crop rect is created when needed, thus enhancing the overall user experience during video editing.
