title: Glide RoundedCornersTransformation not making any changes if scaleType is centerCrop
body: <p>I am using Glide <code>4.3.0</code> and <a href="https://github.com/wasabeef/glide-transformations" rel="nofollow noreferrer">wasabeef/glide-transformations</a> to add a corner radius the bottom left and right corners of my image view. The image  is loaded but the transformation is not applied and I don't see any changes in the corners.</p>
  
  <p>Here's my Glide transformation:</p>
  
  <pre><code>Glide.with(context)
      .load(message.imageUrl)
      .apply(bitmapTransform(new RoundedCornersTransformation(25, 0, RoundedCornersTransformation.CornerType.BOTTOM)))
      .into(aq.id(R.id.ivSingleImage).getImageView());
  </code></pre>
  
  <p>My imports are as follows:</p>
  
  <pre><code>import com.bumptech.glide.Glide;
  import jp.wasabeef.glide.transformations.RoundedCornersTransformation;
  import static com.bumptech.glide.request.RequestOptions.bitmapTransform;
  </code></pre>
  
  <p>The image is loaded but no transformation is applied. Is this implementation correct?</p>
  
  <p>I also tried <code>CornerType.BOTTOM_LEFT</code> and <code>CornerType.BOTTOM_RIGHT</code></p>
  
  <p><strong>EDIT</strong></p>
  
  <p>I noticed that this only occurs when the scaleType is set to centerCrop. If I remove that from the XML, it works but with 2 big spaces on left and right side of the image:</p>
  
  <pre><code>&lt;ImageView
       android:id="@+id/ivSingleImage"
       android:layout_width="match_parent"
       android:layout_height="100dp"
       android:layout_marginRight="5dp"
       android:layout_weight="1"
       android:background="@color/white"
       android:scaleType="centerCrop" &lt;!--Removing this works. But leaves two spaces on left and right sides--&gt;
       android:layout_marginEnd="5dp" /&gt;
  </code></pre>
  
  <p>Referring to the update^, how can I have the image centerCrop and still have a rounded transformation?</p>
