 * Rendition is a read only representation of a particular rendition of an {@link Asset}.

 * Rendition is an extension of a Sling Resource, therefore its adaptable.

 * Rendition is created by {@link Asset#setRendition(String, java.io.InputStream, java.util.Map)} and can be
 * retrieved either via {@link Asset#getRendition(String)} or by adapting a rendition {@link Resource}
 * to a Rendition type.

 *     Asset asset = assetManager.getAsset("/path/to/asset/document.pdf");
 *     asset.setRendition("thumbnail.jpg", java.io.InputStream, java.util.Map);
 *
 *     // to get rendition
 *     Rendition rendition = asset.getRendition("thumbnail.jpg");
 *
 *     // to get rendition by adapting
 *     Rendition rendition = resource.adaptTo(Rendition.class);
