title: MUI: Overriding easing/timing function in Slide Transition component
body: <p>How do I add easings to the Material-UI <code>Slide</code> component? I'm not seeing the props that would allow this. But I read something somewhere about spreading props?</p>
  <pre><code>&lt;Slide
    in={variable}
    timeout={500}
    direction=&quot;right&quot;
    mountOnEnter={true}
    unmountOnExit={true}
  &gt;
      &lt;Child /&gt;
  &lt;/Slide&gt;
  </code></pre>
