    public DrawableTypeRequest<URL> fromUrl() {
        return loadGeneric(URL.class);
    }
Returns a request builder that uses the {@link com.bumptech.glide.load.model.ModelLoaderFactory} currently
registered for {@link URL} to load the image represented by the given {@link URL}. Defaults to
{@link com.bumptech.glide.load.model.stream.HttpUrlGlideUrlLoader} and
{@link com.bumptech.glide.load.data.HttpUrlFetcher} to load {@link URL} models.

@deprecated The {@link URL} class has
<a href="http://goo.gl/c4hHNu">a number of performance problems</a> and should generally be avoided when
possible. Prefer {@link #load(Uri)} or {@link #load(String)}.
