Further, the backing store idea is ``obvious.'' When I was a 13 year old BASIC programmer I thought of it, and I'd be surprised if fewer than half of the world's 13 year old BASIC programmers thought of it. -- Michael Pereckas * InterNet: m-pereckas@uiuc.edu * just another student...

When I was twelve I wrote a text windowing package in Turbo Pascal 2.0; it was kind of handy, actually. It did the backing store, both in the sense that it would save what was underneath a window if you requested it, and it would change the saved area according to what you wrote into a window. Later on I added an assembly-language routine which would draw shadows onto windows beneath a window in the hierarchy - real shadows, cast further across according to how high one window was above another, not just the standard fixed-size shadow border. Of course, I spent so much time on that (twelve-year old programmers are rarely masters of source code control) I never actually thought of anything which needed such an interface. Big :-) here, I don't mean to brag (too much). -- Kevin Martin sigma@rpi.edu
