title: Rotating axes label text in 3D matplotlib
body: <p>How do I rotate the z-label so the text reads (bottom => top) rather than (top => bottom)?</p>
  
  <pre><code>import matplotlib.pyplot as plt
  from mpl_toolkits.mplot3d import Axes3D
  
  fig = plt.figure()
  ax = fig.add_subplot(111, projection='3d')
  ax.set_zlabel('label text flipped', rotation=90) 
  ax.azim = 225
  plt.show()
  </code></pre>

  <p>I want this to hold no matter what my <code>ax.azim</code> setting is. This seems to be an <a href="https://github.com/matplotlib/matplotlib/issues/1037" rel="noreferrer">old feature request on github</a> but there isn't a work on it. Is there a workaround?</p>
