Graphics vs. window managers

[bill One]

> I'm glad to find another term.

I used to be a graphics programmer, but I've been away from
it for a few years.    Since the last message I've been
doing some literature catchup.

"Computer Graphics, Principles and Practice" by
Foley, van Dam, Feiner, and Hughes has some comments
I feel relevant to this piece of the discussion.

"The window management system is first and foremost a
resource manager...  It allocates the resource of
screen area to various programs ... and then assists
in managing these screen areas so that the programs
do not interfere with one another."

"A window-management system has two important parts.
The first is the "Window Manager", with which the user
interacts... The second is the underlying functional
component, the "Window System", which actually causes 
windows to be created, opened, closed, ..."


Although I personally love the term
"screen real-estate manager".
