title: Different figsize definition in Matplotlib 2.0
body: <p>I have recently updated matplotlib from 1.5 to 2.0
  I have noticed a difference in the definition of <code>figsize</code> parameter in <code>plt.subplots</code>:</p>
  
  <ul>
  <li>In matplotlib 1.5, figsize would set the dimension of the <strong>window</strong> generated</li>
  <li>In matplotlib 2.0, figsize would set the dimension of the <strong>plot only</strong></li>
  </ul>
  
  <p>So to make an example, I used to set figsize = (23, 8) that would generate a window that almost perfectly fitted the width of my screen.
  Now the same parameters generate a window that exceeds the width of the screen, but if I center the window I see that the actual plot fits the window of the screen. </p>
  
  <p>Is there a way to revert to previous convention, where I specify the size of the window? </p>
