Some programs that are extremely graphics-intensive don't immediately
update the screen. This is so that the change being made by the user can
be finished before the screen is updated.

The alternative in some cases would be almost constantly waiting for the
screen to update, a serious hindrance for the user.

Now that graphics systems are so much more efficient than several years
ago, most programs instantly update, and require far greater graphics
resources (1-4MB video cards are standard in PCs now).
