title: TextInputLayout: Set box stroke color programmatically (highlighted and unhighlighted)
body: <p>I'm trying to use these material text fields with the box outline style. I see that there's a property called <code>boxStrokeColor</code> which lets me set the stroke  <strong>only when the text field is highlighted</strong> when it's not highlighted it seems to pull that color from the global theme's <code>colorPrimary</code> value.</p>
  
  <p>In our app the user can set their own background color for certain views and I'd like to change the stroke color of the text field to a suitable contrasting color.</p>
  
  <p>Is there any clean way to set the unhighlighted box stroke color programmatically?</p>
