title: Fixed window size in a chrome extension
body: <p>I'm building a Google Chrome Extension. I want to create a popup window using the 
  <a href="https://developer.chrome.com/extensions/windows" rel="nofollow">chrome.windows.create API</a>. Everything works but I don't know how to create the window with fixed size( user can't resize the window, also the maximize button should be disabled).
  Is it possible to do this?</p>
