title: Rotate ImageView and keep original size
body: <p>Ok I have tried with many different ways rotating the <code>ImageView</code> using <code>Matrix</code> but I can't find how to rotate it without changing its size. I'm trying to rotate a circle, literally a purple circle. This is what happens:</p>
  
  <p>When its on 0, 90, 180, 260 it have the correct size, but when the value is any one between those the image change it size.</p>
  
  <p>Like 0-45 it gets smaller 45-90 it gets bigger until it reaches original size. I know that its doing it because even that the image is a circle its really a square bitmap.</p>
  
  <p>Anyone can help me out?</p>
