Make tempo lines physical_screen_height high, add xml null check, Use clicked_regionview directly to calculate region movement. Using drag_info.data may result in the wrong regionbiew being used, don't use canvas coords for region_drag_finished_callback x calculation (eliminates speed adjustment), prevent incorrect updates on dropped regions by updating canvas before placing region copies.
