title: Picasso's Target and centerCrop() and fit()
body: <p>I have an image on my server and I want to display it using Picasso on my Android client.
  I want to add a default image when the image is loading on Picasso so I am using <code>Target</code> as follows:</p>
  
  <pre><code>Picasso.with(UserActivity.this).load(imageUri.toString()).transform(new RoundedTransformation(500, 1)).into(
  new Target() {
      @Override
      public void onBitmapLoaded(Bitmap bitmap, Picasso.LoadedFrom from) {
          userPic.setImageBitmap(bitmap);
      }
  
      @Override
      public void onBitmapFailed(Drawable drawable) {
          userPic.setImageBitmap(defaultDrawable);
      }
  
      @Override
      public void onPrepareLoad(Drawable drawable) {
          userPic.setImageBitmap(defaultDrawable);
      }
  });
  </code></pre>
  
  <p>I want to <code>centerCrop()</code> and <code>fit()</code> this image but it gives me an error and it tells me that I cant use them with Target. Is there anyway to use these features on Picasso? Why don't they allow these two functions with <code>Target</code>?</p>
