title: Glide 4.13.0 : thumbnail(float) is deprecated
body: <p>Just updated Glide to Version <strong>4.13.0</strong> and getting this deprecation warning.</p>
  <p>On checking the release page, I found this:<a href="https://i.stack.imgur.com/8J3Pm.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/8J3Pm.png" alt="enter image description here" /></a></p>
  <p>So, what should be the appropriate equivalent to this part of code?</p>
  <pre><code>GlideApp.with(holder.itemView.getContext())
              .load(sr)
              .thumbnail(0.2f)
              .placeholder(R.drawable.background_splash)
              .into(holder.album);
  </code></pre>
  <p><strong>What I tried:</strong>

  <p>I think the syntax should be something like this but confused on what to pass to the constructor.</p>
