 * This class displays a modal dialog-like snippet.
 *
 * To use PopupWebChromeItem:
 *
 * 1. Add data-GinebraItemType="popup" to the DIV element defining your
 *    snippet in chrome.html
 *
 * 2. Add data-GinebraPopupModal="false" to the DIV to prevent the system
 *    from dimming the other items on the screen while your popup is displayed.
 *
 * 3. Connect to the externalMouseEvent signal AFTER chromeLoadComplete
 *    has been emitted:
 *
 *      window.chrome.chromeComplete.connect(chromeLoadComplete);
 *
 *      function chromeLoadComplete() {
 *        window.snippets.ContextMenuId.externalMouseEvent.connect(
 *          function(type, name, description) {
 *            if (name == "QGraphicsSceneMouseReleaseEvent") {
 *              window.snippets.ContextMenuId.hide();
