-/*
- * ShrinkVertically -- optional click-and-drag horizontal scrolling of the board.
- *
- * Like the Trello board canvas: press the empty board background and drag left/right
- * to scroll #board-container horizontally. The pan only starts on empty background --
- * pressing a task card, a drag handle, or any interactive control is ignored, so this
- * never interferes with Kanboard's own card and column drag-and-drop.
- *
- * Loaded only when the "Drag the board background to scroll" setting is enabled.
