/* This code is called when you finish resizing a view by dragging the
corner tab, but I think this implementation is lousy and will surprise
the user more often than it will do what they are trying to do. What
I really need to be doing here is do a rewrite such that *no* sashes
move except the ones immediately to the bottom and right of this window,
and handle the case where you resize a window larger than it's neighbors
by destroying the neighbors.
But this will do for now. */
