The movement code, when deciding on an item or link that matches the desired direction, will check five points on the object/links area.. center, left edge, right edge, top edge, and bottom edge. For each of these, it makes sure that at that point, clicking will actually get passed to it. Otherwise, it moves onto one of the other edges. This helps avoid issues where links weren't working because standard scene objects were partially obscuring them.
