- Fixed: DragScroll locked on some rare occasions.
(this does not fix the problem where the SDL misses the release event, but fixes all other case)
- Fixed: Unable to scroll when out of map bounds
- Fixed: Release of the Left mouse-button was handled as a click on the map when Scroll mode is Trigger (Manual) Scroll.
- Fixed: Scroll did not start when clicking on the scroll-border on Trigger (Manual) Scroll mode
