What you are forgetting about GEM is that the window stuff is provided
for your convenience: you don't HAVE to call or enable them; you
can just write your own.

For example, create a window with no title bar, no close box, no full
box, no size box, no sliders and no arrows.  Wow! A rectangle! But this
is a rectangle which gets redraw messages and other window handling. 
Now, you put your OWN stuff into the window: your own scroll bars (with
page numbers if you like), your own title bar (with extra gadgets if you
like), etc.  All these things can be objects, and AES will help you
manage them and tell when the mouse is clicked on them. 

AES provides the primitives for doing these things, IN ADDITION TO the
high-level management routines, which you can use if you're satisfied
with them.  If you aren't, go out and make some of your own.
