The existence of -[NSView sortSubviewsUsingFunction:context:] seems
to imply there is a very specific order in the way subviews are
drawn and that that order can be changed. Both of which would be
required for reliably overlapping views.

If your views never draw in the overlapping portions, you may be
OK, but you are outside normal framework usage patterns.
