title: How to get markers with no fill, from seaborn 0.11+
body: <p><code>matplotlib.pyplot.scatter()</code> has a <code>facecolors=None</code> argument that will give datapoints the appearance of being hollow on the inside. How to get the same look for <code>seaborn.jointplot()</code>?</p>
  <p>The same argument was found in previous versions of seaborn but was removed for some reason in the latest version (0.11).</p>
