Is there a recommended way to float Cocoa controls on top of an

In Carbon, we were able to do this by creating one window which
contained an AGL surface, and then a separate Carbon window. We
"combined" the two windows with window groups and the visual effect
worked.
I believe window groups can be simulated/implemented via child
windows. See addChildWindow:ordered:
I'd be OK with this but I don't know if there is a Cocoa equivalent
to window groups, and if there is a simpler way, I'd like to know
more. I do know that, in general, Cocoa does not support Z-ordering
for controls, so that seems like a potential stumbling block.
When you speak of z-ordered, it's true that if you have a set of
sibling controls (views), z-order amongst them is undefined (as well
as the fact you cannot overlap them without side-effects).
To achieve a well-defined order, you would need to use subviews.
Do you have the need for overlapping controls?
