Calling Graphics.drawImage( image, x, y, observer ) results in an endless
repaint loop when observer is non null and the image was retrieved via
Component.createImage(width,height).
Note: this does not happen for Image's created via Toolkit.getImage()...

Testcase follows

Changing the call to drawImage( image, x, y, null ) makes the program work.
However, an Image create by createImage(width,height) should be completely
initialized at once: there is no image data to read asynchronously...

This prints:

Got the image: gnu.java.awt.peer.gtk.GtkImage@ef01d050
paint 1
1 repaints, probably ok.

Fixed by Sven's image work.  Closing.
