title: Picasso center image without resizing into ImageView
body: <p>I've come across this simple problem with the <code>Picasso library</code>. I haven't find any way to put an image into <code>ImageView</code> center it like <code>android:ScaleType="center"</code> does without cropping. Do you have any ideas about how to solve this ? My problem is that I don't know at the runtime the height and width of the <code>BitMap</code> I download so I can't use <code>resize()</code> properly.</p>
