title: How to change marker fillstyle in seaborn lmplot?
body: <p>Is it possible to change the fillstyle of a scatterplot marker in a seaborn lmplot?</p>
  
  <p>I tried: `</p>
  
  <pre><code>sns.lmplot(x=x, 
             y=y, 
             hue=hue, 
             hue_order = hue_order,
             markers=markers,
             scatter_kws = {'fillstyle':'none'})
  </code></pre>
  
  <p>But I get the error:</p>
  
  <pre><code>AttributeError: Unknown property fillstyle
  </code></pre>
  
  <p>Is fillstyle really not supported for an lmplot <code>scatter_kws</code> argument, or am I just doing something wrong?</p>
