title: When I should use windowDrawsSystemBarBackgrounds attribute?
body: <p>I read some articles about android fitsSystemWindows attribute and customized behavior in some widgets for that (i.e. navigation drawer) and there is no questions. But from documentation I can't really understand the difference between windowTranslucentStatus and windowDrawsSystemBarBackgrounds. Can someone please explain when each of this attribute should/shouldn't be used?</p>
  
  <p>I suppose that I need to use windowTranslucentStatus + fitsSystemWindows and windowTranslucentNavigation + clipToPadding, but what is windowDrawsSystemBarBackgrounds for?</p>
