title: Is there any possibility to change speed of a loaded GIF by Glide
body: <p>I'm trying to change the speed of a loaded GIF by Glide :</p>
  <pre><code>Glide.with(recordroo.this)
       .asGif().load(outputPath)
       .listener(new RequestListener&lt;GifDrawable&gt;() {
                 @Override
                 public boolean onLoadFailed(@Nullable GlideException e, Object model, Target&lt;GifDrawable&gt; target, boolean isFirstResource) {
                       return false;
                 }
  
                 @Override
                 public boolean onResourceReady(GifDrawable resource, Object model, Target&lt;GifDrawable&gt; target, DataSource dataSource, boolean isFirstResource) {
                        return false;
                 }
         }).into(userGifView);
  </code></pre>
  <p>I tried the following :</p>
  <pre><code>Drawable userDrawable = userGifView.getDrawable();
   if (userDrawable instanceof Animatable) {
        ((Animatable) userDrawable).; //no speed method exists.
   }
  
  Drawable userDrawable = userGifView.getDrawable();
   if (userDrawable instanceof GifDrawable) {
        ((GifDrawable) userDrawable).; //no speed method exists.
   }
  </code></pre>
  <p>But there's no speed method to use.</p>
