-/**
- * @fileoverview provides a reusable picasa album UI component given a public
- * picasa album URL.
- *
- * TODO(user): implement the javascript viewer, for users without flash. Get it
- * from the Gmail Picasa gadget.
- *
- * goog.ui.media.PicasaAlbum is actually a {@link goog.ui.ControlRenderer}, a
- * stateless class - that could/should be used as a Singleton with the static
- * method {@code goog.ui.media.PicasaAlbum.getInstance} -, that knows how to
- * render picasa albums. It is designed to be used with a
- * {@link goog.ui.Control}, which will actually control the media renderer and
- * provide the {@link goog.ui.Component} base. This design guarantees that all
- * different types of medias will behave alike but will look different.
- *
- * goog.ui.media.PicasaAlbum expects {@code goog.ui.media.PicasaAlbumModel}s on
- * {@code goog.ui.Control.getModel} as data models, and render a flash object
- * that will show a slideshow with the contents of that album URL.
- *
- * Example of usage:
- *
- * <pre>
- *   var album = goog.ui.media.PicasaAlbumModel.newInstance(
- *       'http://picasaweb.google.com/username/SanFranciscoCalifornia');
- *   goog.ui.media.PicasaAlbum.newControl(album).render();
- * </pre>
- *
- * picasa medias currently support the following states:
- *
- * <ul>
- *   <li> {@link goog.ui.Component.State.DISABLED}: shows 'flash not available'
- *   <li> {@link goog.ui.Component.State.HOVER}: mouse cursor is over the album
- *   <li> {@link goog.ui.Component.State.SELECTED}: flash album is shown
- * </ul>
- *
- * Which can be accessed by
- *
- * <pre>
- *   picasa.setEnabled(true);
- *   picasa.setHighlighted(true);
- *   picasa.setSelected(true);
- * </pre>
- *
- *
- * @supported IE6, FF2+, Safari. Requires flash to actually work.
- *
- * TODO(user): test on other browsers
