That's right, Joe, this is a more logical way to do G00 windows.
Fortunately, that's how it's implemented.  The overhead is in the
part of layers that manages "dicing", a rectangular decomposition
of the screen area that can represent any layer at any depth
as a union of rectangles.

I don't know where in History Rob picked up the ">5< layers" 
thing, but I've never seen anything of like that in Intuition.
It would be much worse when moving the window.

)Much better idea -> Make layers be nestable. Then you could do
)something like this:
)
)rast=screen.RastPort;
)
)	nw.Raster=rast;
)	win1=OpenWindow(&nw);
)
)	nw2.Raster=win1->Raster;
)	win2=OpenWindow(&nw2);
)
)This would place win2 inside of win1, much like windows are
)now contained in screens.
)This would provide GIMMEZEROZERO type windows for free, so to speak.

Yes, something called "panes."

)I suppose the guys at CBM will think this is hard to do or something,
)right ? :-)

A simple matter of programming ...  Actually, I've found a nice
spot to hook that in, so maybe some day ...
