How many WindowInsets are there?
<p>I do not understand about WindowInsets rects, because docs says that:</p>

<blockquote>
  <p>The system window inset represents the area of a full-screen window that is partially or fully obscured by the status bar, navigation bar, IME or other system windows.</p>
</blockquote>

<p>So, multiple WindowInsets can be there each with its own rect (one for status bar, another for Navigation Bar ...), and how can I retrieve them?</p>

<p>Or is there only one WindowInsets and its left-top-right-bottom coordinates are the rect of the available window for the app?</p>
