  35  * Shows other elements inside a popup window.
  36  *
  37  * To apply, add the attribute data-role="popupwindow" to a <div> element inside
  38  * a page. Alternatively, call popupwindow()
  39  * on an element, eg :
  40  *
  41  *     $("#mypopupwindowContent").popupwindow();
  42  * where the html might be :
  43  *     <div id="mypopupwindowContent"></div>
  44  *
  45  * To trigger the popupwindow to appear, it is necessary to make a call to its
  46  * 'open()' method. This is typically done by binding a function to an event
  47  * emitted by an input element, such as a the clicked event emitted by a button
  48  * element. The open() method takes two arguments, specifying the x and y
  49  * screen coordinates of the center of the popup window.
  50
  51  * You can associate a button with a popup window like this:
  52  *      <div id="mypopupContent" style="display: table;" data-role="popupwindow">
  53  *          <table>
  54  *              <tr> <td>Eenie</td>   <td>Meenie</td>  <td>Mynie</td>   <td>Mo</td>  </tr>
  55  *              <tr> <td>Catch-a</td> <td>Tiger</td>   <td>By-the</td>  <td>Toe</td> </tr>
  56  *              <tr> <td>If-he</td>   <td>Hollers</td> <td>Let-him</td> <td>Go</td>  </tr>
  57  *              <tr> <td>Eenie</td>   <td>Meenie</td>  <td>Mynie</td>   <td>Mo</td>  </tr>
  58  *          </table>
  59  *      </div>
  60  * <a href="#myPopupContent" data-rel="popupwindow" data-role="button">Show popup</a>
  61  *
  62  * Options:
  63  *
  64  *     theme: String; the theme for the popupwindow contents
  65  *                   Default: null
  66  *
  67  *     overlayTheme: String; the theme for the popupwindow
  68  *                   Default: null
  69  *
  70  *     shadow: Boolean; display a shadow around the popupwindow
  71  *             Default: true
  72  *
  73  *     corners: Boolean; display a shadow around the popupwindow
  74  *             Default: true
  75  *
  76  *     fade: Boolean; fades the opening and closing of the popupwindow
  77  *
  78  *     transition: String; the transition to use when opening or closing
  79  *                 a popupwindow
  80  *                 Default: $.mobile.defaultDialogTransition
  81  *
  82  * Events:
  83  *      popupbeforeposition: triggered after a popup has completed preparations for opening, but has not yet opened
  84  *      popupafteropen: triggered after a popup has completely opened
  85  *      popupafterclose triggered when a popup has completely closed
