The old method: The "old" method used the node dimensions to get a number of lines and checked if they intersect with the node link. Issue with this is that only a small part of the actual node surface is checked, making the method a bit unpredictable or unresponsive. The new method: The new method checks for intersections within the entire node surface. If multiple links are intersected, the node with the smallest distance from the *upper left corner* to the link is chosen. Reviewed by @campbellbarton (tm)
