/**
 * Standard images provided by the JavaScript UI plug-in. This class offers access to the 
 * standard images in two forms:
 * <ul>
 *   <li>Use <code>ISharedImages.getImage(IMG_OBJS_<i>FOO</i>)</code> 
 *    to access the shared standard <code>Image</code> object (caller must not
 *    dispose of image).</li>
 *   <li>Use <code>ISharedImages.getImageDescriptor(IMG_OBJS_<i>FOO</i>)</code> 
 *    to access the standard <code>ImageDescriptor</code> object (caller is 
 *    responsible for disposing of any <code>Image</code> objects it creates using
 *    this descriptor).</li>
 * </ul>
 * <p>
 * This interface is not intended to be implemented by clients.
 * </p> 

 *
 * Provisional API: This class/interface is part of an interim API that is still under development and expected to
 * change significantly before reaching stability. It is being made available at this early stage to solicit feedback
 * from pioneering adopters on the understanding that any code that uses this API will almost certainly be broken
 * (repeatedly) as the API evolves.
