Smooth intuitive interaction to easily edit spans on timeline. The biggest effort here was to fix undo/redo stack to keep UX convenient and predictable. Only one item in history is created with final state for these actions: - new region is drawn - existing region was edited by drag-n-drop - existing region was edited in info panel: - in input and the focus was moved away - in input by clicking on up/down arrows

Allows smooth intuitive interaction to easily edit spans on timeline.
The biggest effort here was to fix undo/redo stack to keep UX convenient and predictable. Only one item in history is created with final state for these actions:
Video#startDrawing(),Video#finishDrawing()andTimelineRegion#setRange()(former less correctsetRanges()) were edited to acceptmodeto distinguish actions needed andregionto find current region to edit it instead of creating a new one.The main entry point is still
Timeline/Views/Frames#onFrameScrub()— now extended to handle drawing new region, editing existing region and updating current position in a Video tag.
