 The difference between alternate edges and normal edges require a bit of explaining. Imagine we have a view at position (0, 0) of size (100, 100) named *myView*. If we do `myView.right = 200`, then its position is now (200, 0) and its size remains unchaged. However, back when our view was located at (0, 0), if we had done `myView.right2 = 200`, then *myView* would have still been at (0, 0) but would have had a size of (200, 0).
 
-So basically, *setting a normal edge's position drags the whole view along with that edge but setting an alternative edge's position drags just that edge*. And don't worry if you, for example, try to drag a left edge past that view's right edge. Edge swapping is done automatically so you don't have to worry about.
