Views don't become (in)active, windows do. Since there are plenty of
things that might be interested in that (Window menu, controllers,
views…), it's done as a notification so all interested parties can
listen for it.

This surprises you? It's called -viewDidMoveToWindow after all. You
would start listening for all window change notifications there, and
then your view's notification handler would check to see if its window
is the one being notified about and update its drawing accordingly.
