You could capture the whole screen using gWorlds, but they are very
memory intensive, especially if you have a lot of colors and a high
resolution. It is often far more efficient to redraw the screen
programatically than to constantly be saving the contents of the screen
I think.

Also, what if the thing that messed up your pixels (a dialog box, for
instance) had stuff done to it that changed the data displayed? You'd
have to re-draw it anyway.

I think certain apps do the kind of thing you are talking about (games
come to mind), but I have always had good luck redrawing the windows
when I needed to.
