Displaying Pictures with AWT

/***********************************
Demonstrates how pictures can be displayed in a standard AWT Frame.
These commands are NOT suitable for animation, as they
images are not redrawn automatically and smoothly enough.
The basic idea is to CHANGE the pictures or positions,
and then use REPAINT to redisplay the page.
