/**
 * <p>
 * Gallery expects contents to have exactly 2 levels of hierarchy, with
 * groups as the root elements and image thumbnails as direct children of
 * the groups. This method accepts ITreeContentProvider and
 * ITreePathContentProvider as-is, and relies on the providers to return
 * contents with the correct structure.
 * </p>
 * <p>
 * This method also accepts IStructuredContentProvider and wraps it in a
 * FlatTreeContentProvider with an empty string as the root node. If you
 * need a different root node, construct your own FlatTreeContentProvider
 * and pass it here. If you want the Gallery to suppress the collapsable
 * group header, call
 * </p>
 * <code>getGallery().setGroupRenderer(new NoGroupRenderer());</code>
