	 * Are we moving focus based on the leave?  There are 2 steps to
	 * this:
	 * - Scr->FocusRoot is our "are we automatically changing focus
	 *   based on the leave" flag.  This gets unset when ClickToFocus
	 *   is config'd or a window is f.focus'd.
	 * - Then we check the detail for the focus leaving.  We're only
	 *   getting here for normal entry/exits.  Most cases outside of
	 *   the icon manager peek ahead in the event queue for any
	 *   Enter's, and don't do anything if there are; if there were,
	 *   we'd be moving the focus when we get them, so no point doing
	 *   it twice.  So the remainder here assumes there aren't any
	 *   Enters waiting.
	 *
	 *   See
	 *   <https://www.x.org/releases/X11R7.7/doc/libX11/libX11/libX11.html#Normal_EntryExit_Events>
	 *   for details of the cases.  So, when do we want to un-set the
	 *   focus?  Let's look at each doc'd value...
	 *   - NotifyAncestor means we're leaving a subwindow for its
	 *     parent.  That means the root, so, yep, we want to yield
	 *     focus up to it.
	 *   - NotifyNonLinear means we're leaving a window for something
	 *     that isn't a parent or child.  So we should probably yield
	 *     focus in this case too.
	 *   - NotifyInferior means we're leaving a window for a
	 *     subwindow of it.  From the WM perspective, that means
	 *     we're leaving focus where it was.
	 *   - NotifyVirtual means we're in the middle of an ascending
	 *     sequence.  Nothing to do; the Ancestor handling already
	 *     did the job.
	 *   - NotifyNonLinearVirtual is another "in the middle" case, so
	 *     we skip handling there too; the endpoints will do
	 *     whatever's necessary.
