org.pentaho.reporting.libraries.base.util.WaitingImageObserver
This image observer blocks until the image is completely loaded. AWT defers the loading of images until they are painted on a graphic.
While printing reports it is not very nice, not to know whether a image was completely loaded, so this observer forces the loading of the image until a final state (either ALLBITS, ABORT or ERROR) is reached. @author Thomas Morgner
