Image flush test
This applet tests the behavior of the Image and MediaTracker
classes when the Image.flush() method is used to abort an
image download. Try hitting the Flush button while the
image is downloading and after the image is downloaded.
The Redraw button flushes the image and then induces it
to reload. The Checkboxes toggle between using a good
image and an image that doesn't exist (which will cause
an error condition). The error condition should be
flushable by hitting the flush button.
