Set the stage much faster
The previous two programs took a while to set the stage.
Viewers don't want to watch the stage being set, so we need to do something about that.
We will deal with that problem in two steps.
In the next program, we will reduce the time that it takes to set the stage.
In a subsequent program, we will make all of the objects invisible during the time that the stage is being set to eliminate any undesirable flashing on the screen.
