/**
 * Class: mxWindow
 * 
 * Basic window inside a document.
 * 
 * Examples:
 * 
 * Creating a simple window.
 *
 * (code)
 * var tb = document.createElement('div');
 * var wnd = new mxWindow('Title', tb, 100, 100, 200, 200, true, true);
 * wnd.setVisible(true); 
 * (end)
 *
 * Creating a window that contains an iframe. 
 * 
 * (code)
 * var frame = document.createElement('iframe');
 * frame.setAttribute('width', '192px');
 * frame.setAttribute('height', '172px');
 * frame.setAttribute('src', 'http://www.example.com/');
 * frame.style.backgroundColor = 'white';
 * 
 * var w = document.body.clientWidth;
 * var h = (document.body.clientHeight || document.documentElement.clientHeight);
 * var wnd = new mxWindow('Title', frame, (w-200)/2, (h-200)/3, 200, 200);
 * wnd.setVisible(true);
 * (end)
 * 
 * To limit the movement of a window, eg. to keep it from being moved beyond
 * the top, left corner the following method can be overridden (recommended):
 * 
 * (code)
 * wnd.setLocation = function(x, y)
 * {
 *   x = Math.max(0, x);
 *   y = Math.max(0, y);
 *   mxWindow.prototype.setLocation.apply(this, arguments);
 * };
 * (end)
 * 
 * Or the following event handler can be used:
 * 
 * (code)
 * wnd.addListener(mxEvent.MOVE, function(e)
 * {
 *   wnd.setLocation(Math.max(0, wnd.getX()), Math.max(0, wnd.getY()));
 * });
 * (end)
 * 
 * To keep a window inside the current window:
 * 
 * (code)
 * mxEvent.addListener(window, 'resize', mxUtils.bind(this, function()
 * {
 *   var iw = window.innerWidth || document.documentElement.clientWidth || document.body.clientWidth;
 *   var ih = window.innerHeight || document.documentElement.clientHeight || document.body.clientHeight;
 *   
 *   var x = this.window.getX();
 *   var y = this.window.getY();
 *   
 *   if (x + this.window.table.clientWidth > iw)
 *   {
 *     x = Math.max(0, iw - this.window.table.clientWidth);
 *   }
 *   
 *   if (y + this.window.table.clientHeight > ih)
 *   {
 *     y = Math.max(0, ih - this.window.table.clientHeight);
 *   }
 *   
 *   if (this.window.getX() != x || this.window.getY() != y)
 *   {
 *     this.window.setLocation(x, y);
 *   }
 * }));
 * (end)
 *
 * Event: mxEvent.MOVE_START
 *
 * Fires before the window is moved. The <code>event</code> property contains
 * the corresponding mouse event.
 *
 * Event: mxEvent.MOVE
 *
 * Fires while the window is being moved. The <code>event</code> property
 * contains the corresponding mouse event.
 *
 * Event: mxEvent.MOVE_END
 *
 * Fires after the window is moved. The <code>event</code> property contains
 * the corresponding mouse event.
 *
 * Event: mxEvent.RESIZE_START
 *
 * Fires before the window is resized. The <code>event</code> property contains
 * the corresponding mouse event.
 *
 * Event: mxEvent.RESIZE
 *
 * Fires while the window is being resized. The <code>event</code> property
 * contains the corresponding mouse event.
 *
 * Event: mxEvent.RESIZE_END
 *
 * Fires after the window is resized. The <code>event</code> property contains
 * the corresponding mouse event.
 *
 * Event: mxEvent.MAXIMIZE
 * 
 * Fires after the window is maximized. The <code>event</code> property
 * contains the corresponding mouse event.
 * 
 * Event: mxEvent.MINIMIZE
 * 
 * Fires after the window is minimized. The <code>event</code> property
 * contains the corresponding mouse event.
 * 
 * Event: mxEvent.NORMALIZE
 * 
 * Fires after the window is normalized, that is, it returned from
 * maximized or minimized state. The <code>event</code> property contains the
 * corresponding mouse event.
 *  
 * Event: mxEvent.ACTIVATE
 * 
 * Fires after a window is activated. The <code>previousWindow</code> property
 * contains the previous window. The event sender is the active window.
 * 
 * Event: mxEvent.SHOW
 * 
 * Fires after the window is shown. This event has no properties.
 * 
 * Event: mxEvent.HIDE
 * 
 * Fires after the window is hidden. This event has no properties.
 * 
 * Event: mxEvent.CLOSE
 * 
 * Fires before the window is closed. The <code>event</code> property contains
 * the corresponding mouse event.
 * 
 * Event: mxEvent.DESTROY
 * 
 * Fires before the window is destroyed. This event has no properties.
 * 
 * Constructor: mxWindow
 * 
 * Constructs a new window with the given dimension and title to display
 * the specified content. The window elements use the given style as a
 * prefix for the classnames of the respective window elements, namely,
 * the window title and window pane. The respective postfixes are appended
 * to the given stylename as follows:
 * 
 *   style - Base style for the window.
 *   style+Title - Style for the window title.
 *   style+Pane - Style for the window pane.
 * 
 * The default value for style is mxWindow, resulting in the following
 * classnames for the window elements: mxWindow, mxWindowTitle and
 * mxWindowPane.
 * 
 * If replaceNode is given then the window replaces the given DOM node in
 * the document.
 * 
 * Parameters:
 * 
 * title - String that represents the title of the new window.
 * content - DOM node that is used as the window content.
 * x - X-coordinate of the window location.
 * y - Y-coordinate of the window location.
 * width - Width of the window.
 * height - Optional height of the window. Default is to match the height
 * of the content at the specified width.
 * minimizable - Optional boolean indicating if the window is minimizable.
 * Default is true.
 * movable - Optional boolean indicating if the window is movable. Default
 * is true.
 * replaceNode - Optional DOM node that the window should replace.
 * style - Optional base classname for the window elements. Default is
 * mxWindow.
