title: DialogFragment with clear background (not dimmed)
body: <p>I'm trying to get the background of a <code>DialogFragment</code> to be completely clear.</p>
  
  <p>With setting the style item <code>android:windowIsFloating</code> to true (the default),
  the <code>DialogFragment</code> displays exactly how I want it to, but has a very dimmed background.</p>
  
  <p>By setting <code>android:windowIsFloating</code> to false, I get the clear background I want, but the DialogFragment blows up to about 95% of the screen,
  leaving only a tiny gap around it where you can see through to the view it overlays.</p>
  
  <p>I've tried ton's of tweaks and cannot seem to override this behavior.</p>
  
  <p>Do I need to use a <code>PopupWindow</code> to achieve the desired effects, or are there some style
  items that I can override ?</p>
