title: Android: make ImageButton's image larger
body: <p>I have an ImageButton:</p>
  
  <p><img src="https://i.imgur.com/XeS5c.jpg" alt="button"></p>
  
  <p>I want to make the image (circular play image) bigger. I am aware of <strong>android:scaleType</strong>, but I don't want to stretch the image all the way to the borders of the button. I just want to make it a little bigger, say 120% of the current size.</p>
  
  <p>Is that possible?</p>
