/*Ok, I'm new here but I hope you guys could help me out... I'm trying to take
*an image(dragon.jpg, it's in the same directory as ImageTest.java) and put in
*on a buffer while scaling it down on the x-axis. Eventually I hope to scale
*it down to 0, mirror it, and scale it back up at the same rate so it looks
*as if it is rotating. As of now, all it does is show up at the same size.
*I tried doinga for loop and all but it just doesn't seem to work for me.
*Any help would be appreciated, thanks.
