title: is there maximum figsize in matplotlib?
body: <p>I am trying to save a large picture (which is actually larger than resolution of my display), however I get the same size png pictures when increasing figsize. So for two example below I get exactly the same files: </p>
  
  <pre><code>import matplotlib.pylab as plt
  fig, ax = plt.subplots(nrows=2, ncols=1, figsize=(10, 100))
  ax[0].plot([0, 1], [0, 1])
  ax[1].plot([0, 1], [0, 1])
  fig.savefig('test1.png')
  plt.close()
  </code></pre>
  
  <p>and second:</p>
  
  <pre><code>fig, ax = plt.subplots(nrows=2, ncols=1, figsize=(10, 150))
  ax[0].plot([0, 1], [0, 1])
  ax[1].plot([0, 1], [0, 1])
  fig.savefig('test2.png')
  plt.close()
  </code></pre>
  
  <p>Is there a way to create a larger picture please? </p>
