Well, I see a 'rawBox' slot in the pluggableOutliner which seems 
interesting, but the "raw" indicates that I shouldn't be using it 
directly.

Asking for "senders in family" gets me 'baseBounds', 'position' and 
'position:'. So you might try

     pOutliner position

and

     pOutliner baseBounds height

where pOutliner is the object you are interested in.

This is very complicated since there might be any number of windows 
showing the same world. The object might be "outside the screen" for 
one window and yet right in the middle of another window.

If you don't care about this, then

   | wc |
   wc: topmostOwner anyWindowCanvas.
   (wc offset ## wc size) intersects: baseBounds

seems to get the job done.

Scrollbars in general aren't very popular in Self. What would these do?
