title: Why Picasso debug mode doesn't work?
body: <p>Could anybody tell me, please, why Picasso doesn't indicate debugging? 
  I have following code:          </p>
  
  <pre><code>Picasso.with(MyActivity.this.getApplicationContext()).setDebugging(true);
  Picasso.with(MyActivity.this.getApplicationContext()).load(message).into(imageView);
  </code></pre>
  
  <p>And no indication at left-top corner of picture. In the same time, debugging mode works fine in same application with same context (but for different images). Small ones 150x150 are indicated, but large ones (1400x1400) are not. Does the size of images has matter? 
  Thank you!</p>
