class AsyncImage
extends java.util.concurrent.atomic.AtomicReference<org.eclipse.swt.graphics.ImageData>
implements java.lang.Runnable

An async image that loads itself in the background on an image-fetcher thread. Once its loaded it will trigger a redraw. Sometimes redraws that are not really necessary can be triggered, but that is not relevant in terms of performance for this swt-component.
