AsynchronousLoading (common 5.0.0 API)

All Known Implementing Classes:

ImageBackedFilterableRadianceIcon, RadianceAsyncLoadingIconUIResource
```
public interface AsynchronousLoading
```
This interface is used for asynchronously-loaded contents. For example, the SVG-based implementation of RadianceIcon in SVG Transcoder uses the ExecutorService to load the SVG image in the background. When the image is loaded, the component that contains this image (command button from Flamingo, for example) is notified so that it can repaint itself.
