- * 
- * Bind the delete key to the delete action in an existing editor.
- * 
- * (code)
- * var keyHandler = new mxDefaultKeyHandler(editor);
- * keyHandler.bindAction(46, 'delete');

- * This class uses the <mxDefaultKeyHandlerCodec> to read configuration
- * data into an existing instance. See <mxDefaultKeyHandlerCodec> for a
- * description of the configuration format.
- * 
- * Keycodes:
- * 
- * See <mxKeyHandler>.
- * 
- * An <mxEvent.ESCAPE> event is fired via the editor if the escape key is
- * pressed.
- * 
- * Constructor: mxDefaultKeyHandler
- *
- * Constructs a new default key handler for the <mxEditor.graph> in the
- * given <mxEditor>. (The editor may be null if a prototypical instance for

- * Function: createMenu

- * the following nodes and attributes.
- *
- * Child Nodes: 
- *
- * add - Adds a new menu item. See below for attributes.
- * separator - Adds a separator. No attributes.
- * condition - Adds a custom condition. Name attribute.
- * 
- * The add-node may have a child node that defines a function to be invoked
- * before the action is executed (or instead of an action to be executed).
- *
- * Attributes:
- *
- * as - Resource key for the label (needs entry in property file).
- * action - Name of the action to execute in enclosing editor.
- * icon - Optional icon (relative/absolute URL).
- * iconCls - Optional CSS class for the icon.
- * if - Optional name of condition that must be true(see below).
- * name - Name of custom condition. Only for condition nodes.
- *
- * Conditions:
- *
- * nocell - No cell under the mouse.
- * ncells - More than one cell selected.
- * notRoot - Drilling position is other than home.
- * cell - Cell under the mouse.
- * notEmpty - Exactly one cell with children under mouse.
- * expandable - Exactly one expandable cell under mouse.
- * collapsable - Exactly one collapsable cell under mouse.
- * validRoot - Exactly one cell which is a possible root under mouse.
- * swimlane - Exactly one cell which is a swimlane under mouse.
- *
- * Example:
- *
- * To add a new item for a given action to the popupmenu:
- * 
- * (code)
- * <mxDefaultPopupMenu as="popupHandler">
- *   <add as="delete" action="delete" icon="images/delete.gif" if="cell"/>
- * </mxDefaultPopupMenu>
- * (end)
- * 
- * To add a new item for a custom function:
- * 
- * (code)
- * <mxDefaultPopupMenu as="popupHandler">
- *   <add as="action1"><![CDATA[
- *		function (editor, cell, evt)
- *		{
- *			editor.execute('action1', cell, 'myArg');
- *		}
- *   ]]></add>
- * </mxDefaultPopupMenu>
- * (end)
- * 
- * The above example invokes action1 with an additional third argument via
- * the editor instance. The third argument is passed to the function that
- * defines action1. If the add-node has no action-attribute, then only the
- * function defined in the text content is executed, otherwise first the
- * function and then the action defined in the action-attribute is
- * executed. The function in the text content has 3 arguments, namely the
- * <mxEditor> instance, the <mxCell> instance under the mouse, and the
- * native mouse event.
- *
- * Custom Conditions:
- *
- * To add a new condition for popupmenu items:
- *  
- * (code)
- * <condition name="condition1"><![CDATA[
- *   function (editor, cell, evt)
- *   {
- *     return cell != null;
- *   }
- * ]]></condition>
- * (end)
- * 
- * The new condition can then be used in any item as follows:
- * 
- * (code)
- * <add as="action1" action="action1" icon="action1.gif" if="condition1"/>
- * (end)
- * 
- * The order in which the items and conditions appear is not significant as
- * all connditions are evaluated before any items are created.
- * 
- * Parameters:
- *
- * editor - Enclosing <mxEditor> instance.
- * menu - <mxPopupMenu> that is used for adding items and separators.
- * cell - Optional <mxCell> which is under the mousepointer.
- * evt - Optional mouse event which triggered the menu.

- * Example:
- * 
- * Create a toolbar with a button to copy the selection into the clipboard,

-/**
- * Class: mxEditor
- *
- * Extends <mxEventSource> to implement a application wrapper for a graph that
- * adds <actions>, I/O using <mxCodec>, auto-layout using <mxLayoutManager>,
- * command history using <undoManager>, and standard dialogs and widgets, eg.
- * properties, help, outline, toolbar, and popupmenu. It also adds <templates>
- * to be used as cells in toolbars, auto-validation using the <validation>
- * flag, attribute cycling using <cycleAttributeValues>, higher-level events
- * such as <root>, and backend integration using <urlPost>, <urlImage>,
- * <urlInit>, <urlNotify> and <urlPoll>. 
- * 
- * Actions:
- * 
- * Actions are functions stored in the <actions> array under their names. The
- * functions take the <mxEditor> as the first, and an optional <mxCell> as the
- * second argument and are invoked using <execute>. Any additional arguments
- * passed to execute are passed on to the action as-is.
- * 
- * A list of built-in actions is available in the <addActions> description.
- * 
- * Read/write Diagrams:
- * 
- * To read a diagram from an XML string, for example from a textfield within the 
- * page, the following code is used:
- * 
- * (code)
- * var doc = mxUtils.parseXML(xmlString);
- * var node = doc.documentElement;
- * editor.readGraphModel(node);
- * (end)
- * 
- * For reading a diagram from a remote location, use the <open> method.
- * 
- * To save diagrams in XML on a server, you can set the <urlPost> variable. 
- * This variable will be used in <getUrlPost> to construct a URL for the post 
- * request that is issued in the <save> method. The post request contains the 
- * XML representation of the diagram as returned by <writeGraphModel> in the 
- * xml parameter.
- * 
- * On the server side, the post request is processed using standard
- * technologies such as Java Servlets, CGI, .NET or ASP.
- * 
- * Here are some examples of processing a post request in various languages.
- * 
- * - Java: URLDecoder.decode(request.getParameter("xml"), "UTF-8").replace("\n", "&#xa;")
- * 
- * Note that the linefeeds should only be replaced if the XML is
- * processed in Java, for example when creating an image, but not
- * if the XML is passed back to the client-side.
- * 
- * - .NET: HttpUtility.UrlDecode(context.Request.Params["xml"])
- * - PHP: urldecode($_POST["xml"])
- * 
- * Creating images:
- * 
- * A backend (Java, PHP or C#) is required for creating images. The
- * distribution contains an example for each backend (ImageHandler.java,
- * ImageHandler.cs and graph.php). More information about using a backend
- * to create images can be found in the readme.html files. Note that the
- * preview is implemented using VML/SVG in the browser and does not require
- * a backend. The backend is only required to creates images (bitmaps).
- * 
- * Special characters:
- * 
- * Note There are five characters that should always appear in XML content as
- * escapes, so that they do not interact with the syntax of the markup. These
- * are part of the language for all documents based on XML and for HTML.
- * 
- * - &lt; (<)
- * - &gt; (>)
- * - &amp; (&)
- * - &quot; (")
- * - &apos; (')
- * 
- * Although it is part of the XML language, &apos; is not defined in HTML.
- * For this reason the XHTML specification recommends instead the use of
- * &#39; if text may be passed to a HTML user agent.
- * 
- * If you are having problems with special characters on the server-side then
- * you may want to try the <escapePostData> flag.
- * 
- * For converting decimal escape sequences inside strings, a user has provided
- * us with the following function:
- * 
- * (code)
- * function html2js(text)
- * {
- *   var entitySearch = /&#[0-9]+;/;
- *   var entity;
- *   
- *   while (entity = entitySearch.exec(text))
- *   {
- *     var charCode = entity[0].substring(2, entity[0].length -1);
- *     text = text.substring(0, entity.index)
- *            + String.fromCharCode(charCode)
- *            + text.substring(entity.index + entity[0].length);
- *   }
- *   
- *   return text;
- * }
- * (end)
- * 
- * Otherwise try using hex escape sequences and the built-in unescape function
- * for converting such strings.
- * 
- * Local Files:
- * 
- * For saving and opening local files, no standardized method exists that
- * works across all browsers. The recommended way of dealing with local files
- * is to create a backend that streams the XML data back to the browser (echo)
- * as an attachment so that a Save-dialog is displayed on the client-side and
- * the file can be saved to the local disk.
- * 
- * For example, in PHP the code that does this looks as follows.
- * 
- * (code)
- * $xml = stripslashes($_POST["xml"]);
- * header("Content-Disposition: attachment; filename=\"diagram.xml\"");
- * echo($xml);
- * (end)
- * 
- * To open a local file, the file should be uploaded via a form in the browser
- * and then opened from the server in the editor.
- * 
- * Cell Properties:
- * 
- * The properties displayed in the properties dialog are the attributes and 
- * values of the cell's user object, which is an XML node. The XML node is 
- * defined in the templates section of the config file.
- * 
- * The templates are stored in <mxEditor.templates> and contain cells which
- * are cloned at insertion time to create new vertices by use of drag and
- * drop from the toolbar. Each entry in the toolbar for adding a new vertex
- * must refer to an existing template.
- * 
- * In the following example, the task node is a business object and only the 
- * mxCell node and its mxGeometry child contain graph information:
- * 
- * (code)
- * <Task label="Task" description="">
- *   <mxCell vertex="true">
- *     <mxGeometry as="geometry" width="72" height="32"/>
- *   </mxCell>
- * </Task> 
- * (end)
- * 
- * The idea is that the XML representation is inverse from the in-memory 
- * representation: The outer XML node is the user object and the inner node is 
- * the cell. This means the user object of the cell is the Task node with no 
- * children for the above example:
- * 
- * (code)
- * <Task label="Task" description=""/>
- * (end)
- * 
- * The Task node can have any tag name, attributes and child nodes. The 
- * <mxCodec> will use the XML hierarchy as the user object, while removing the 
- * "known annotations", such as the mxCell node. At save-time the cell data 
- * will be "merged" back into the user object. The user object is only modified 
- * via the properties dialog during the lifecycle of the cell.
- * 
- * In the default implementation of <createProperties>, the user object's
- * attributes are put into a form for editing. Attributes are changed using
- * the <mxCellAttributeChange> action in the model. The dialog can be replaced 
- * by overriding the <createProperties> hook or by replacing the showProperties
- * action in <actions>. Alternatively, the entry in the config file's popupmenu
- * section can be modified to invoke a different action.
- * 
- * If you want to displey the properties dialog on a doubleclick, you can set
- * <mxEditor.dblClickAction> to showProperties as follows:
- * 
- * (code)
- * editor.dblClickAction = 'showProperties';
- * (end)
- * 
- * Popupmenu and Toolbar:
- * 
- * The toolbar and popupmenu are typically configured using the respective
- * sections in the config file, that is, the popupmenu is defined as follows:
- * 
- * (code)
- * <mxEditor>
- *   <mxDefaultPopupMenu as="popupHandler">
- * 		<add as="cut" action="cut" icon="images/cut.gif"/>
- *      ...
- * (end)
- * 
- * New entries can be added to the toolbar by inserting an add-node into the
- * above configuration. Existing entries may be removed and changed by
- * modifying or removing the respective entries in the configuration.
- * The configuration is read by the <mxDefaultPopupMenuCodec>, the format of the
- * configuration is explained in <mxDefaultPopupMenu.decode>.
- * 
- * The toolbar is defined in the mxDefaultToolbar section. Items can be added
- * and removed in this section.
- * 
- * (code)
- * <mxEditor>
- *   <mxDefaultToolbar>
- *     <add as="save" action="save" icon="images/save.gif"/>
- *     <add as="Swimlane" template="swimlane" icon="images/swimlane.gif"/>
- *     ...
- * (end)
- * 
- * The format of the configuration is described in
- * <mxDefaultToolbarCodec.decode>.
- * 
- * Ids:
- * 
- * For the IDs, there is an implicit behaviour in <mxCodec>: It moves the Id
- * from the cell to the user object at encoding time and vice versa at decoding
- * time. For example, if the Task node from above has an id attribute, then
- * the <mxCell.id> of the corresponding cell will have this value. If there
- * is no Id collision in the model, then the cell may be retrieved using this
- * Id with the <mxGraphModel.getCell> function. If there is a collision, a new
- * Id will be created for the cell using <mxGraphModel.createId>. At encoding
- * time, this new Id will replace the value previously stored under the id
- * attribute in the Task node.
- * 
- * See <mxEditorCodec>, <mxDefaultToolbarCodec> and <mxDefaultPopupMenuCodec>
- * for information about configuring the editor and user interface.
- * 
- * Programmatically inserting cells:
- * 
- * For inserting a new cell, say, by clicking a button in the document,
- * the following code can be used. This requires an reference to the editor.
- * 
- * (code)
- * var userObject = new Object();
- * var parent = editor.graph.getDefaultParent();
- * var model = editor.graph.model;
- * model.beginUpdate();
- * try
- * {
- *   editor.graph.insertVertex(parent, null, userObject, 20, 20, 80, 30);
- * }
- * finally
- * {
- *   model.endUpdate();
- * }
- * (end)
- * 
- * If a template cell from the config file should be inserted, then a clone
- * of the template can be created as follows. The clone is then inserted using
- * the add function instead of addVertex.
- * 
- * (code)
- * var template = editor.templates['task'];
- * var clone = editor.graph.model.cloneCell(template);
- * (end)
- * 
- * Resources:
- *
- * resources/editor - Language resources for mxEditor
- *
- * Callback: onInit
- *
- * Called from within the constructor. In the callback,
- * "this" refers to the editor instance.
- *
- * Cookie: mxgraph=seen
- *
- * Set when the editor is started. Never expires. Use
- * <resetFirstTime> to reset this cookie. This cookie
- * only exists if <onInit> is implemented.
- *
- * Event: mxEvent.OPEN
- *
- * Fires after a file was opened in <open>. The <code>filename</code> property
- * contains the filename that was used. The same value is also available in
- * <filename>.
- *
- * Event: mxEvent.SAVE
- *
- * Fires after the current file was saved in <save>. The <code>url</code>
- * property contains the URL that was used for saving.
- *
- * Event: mxEvent.POST
- * 
- * Fires if a successful response was received in <postDiagram>. The
- * <code>request</code> property contains the <mxXmlRequest>, the
- * <code>url</code> and <code>data</code> properties contain the URL and the
- * data that were used in the post request. 
- *
- * Event: mxEvent.ROOT
- *
- * Fires when the current root has changed, or when the title of the current
- * root has changed. This event has no properties.
- *
- * Event: mxEvent.SESSION
- *
- * Fires when anything in the session has changed. The <code>session</code>
- * property contains the respective <mxSession>.
- * 
- * Event: mxEvent.BEFORE_ADD_VERTEX
- * 
- * Fires before a vertex is added in <addVertex>. The <code>vertex</code>
- * property contains the new vertex and the <code>parent</code> property
- * contains its parent.
- * 
- * Event: mxEvent.ADD_VERTEX
- * 
- * Fires between begin- and endUpdate in <addVertex>. The <code>vertex</code>
- * property contains the vertex that is being inserted.
- * 
- * Event: mxEvent.AFTER_ADD_VERTEX
- * 
- * Fires after a vertex was inserted and selected in <addVertex>. The
- * <code>vertex</code> property contains the new vertex.
- * 
- * Example:
- * 
- * For starting an in-place edit after a new vertex has been added to the
- * graph, the following code can be used.
- * 
- * (code)
- * editor.addListener(mxEvent.AFTER_ADD_VERTEX, function(sender, evt)
- * {
- *   var vertex = evt.getProperty('vertex');
- * 
- *   if (editor.graph.isCellEditable(vertex))
- *   {
- *   	editor.graph.startEditingAtCell(vertex);
- *   }
- * });
- * (end)
- * 
- * Event: mxEvent.ESCAPE
- * 
- * Fires when the escape key is pressed. The <code>event</code> property
- * contains the key event.
- * 
- * Constructor: mxEditor
- *
- * Constructs a new editor. This function invokes the <onInit> callback
- * upon completion.
- *
- * Example:
- *
- * (code)
- * var config = mxUtils.load('config/diagrameditor.xml').getDocumentElement();
- * var editor = new mxEditor(config);
- * (end)
- * 
- * Parameters:
- * 
- * config - Optional XML node that contains the configuration.

-/**
- * Class: mxConnectionHandler
- *
- * Graph event handler that creates new connections. Uses <mxTerminalMarker>
- * for finding and highlighting the source and target vertices and
- * <factoryMethod> to create the edge instance. This handler is built-into
- * <mxGraph.connectionHandler> and enabled using <mxGraph.setConnectable>.
- *
- * Example:
- * 
- * (code)
- * new mxConnectionHandler(graph, function(source, target, style)
- * {
- *   edge = new mxCell('', new mxGeometry());
- *   edge.setEdge(true);
- *   edge.setStyle(style);
- *   edge.geometry.relative = true;
- *   return edge;
- * });
- * (end)
- * 
- * Here is an alternative solution that just sets a specific user object for
- * new edges by overriding <insertEdge>.
- *
- * (code)
- * mxConnectionHandlerInsertEdge = mxConnectionHandler.prototype.insertEdge;
- * mxConnectionHandler.prototype.insertEdge = function(parent, id, value, source, target, style)
- * {
- *   value = 'Test';
- * 
- *   return mxConnectionHandlerInsertEdge.apply(this, arguments);
- * };
- * (end)
- * 
- * Using images to trigger connections:
- * 
- * This handler uses mxTerminalMarker to find the source and target cell for
- * the new connection and creates a new edge using <connect>. The new edge is
- * created using <createEdge> which in turn uses <factoryMethod> or creates a
- * new default edge.
- * 
- * The handler uses a "highlight-paradigm" for indicating if a cell is being
- * used as a source or target terminal, as seen in MS Visio and other products.
- * In order to allow both, moving and connecting cells at the same time,
- * <mxConstants.DEFAULT_HOTSPOT> is used in the handler to determine the hotspot
- * of a cell, that is, the region of the cell which is used to trigger a new
- * connection. The constant is a value between 0 and 1 that specifies the
- * amount of the width and height around the center to be used for the hotspot
- * of a cell and its default value is 0.5. In addition,
- * <mxConstants.MIN_HOTSPOT_SIZE> defines the minimum number of pixels for the
- * width and height of the hotspot.
- * 
- * This solution, while standards compliant, may be somewhat confusing because
- * there is no visual indicator for the hotspot and the highlight is seen to
- * switch on and off while the mouse is being moved in and out. Furthermore,
- * this paradigm does not allow to create different connections depending on
- * the highlighted hotspot as there is only one hotspot per cell and it
- * normally does not allow cells to be moved and connected at the same time as
- * there is no clear indication of the connectable area of the cell.
- * 
- * To come across these issues, the handle has an additional <createIcons> hook
- * with a default implementation that allows to create one icon to be used to
- * trigger new connections. If this icon is specified, then new connections can
- * only be created if the image is clicked while the cell is being highlighted.
- * The <createIcons> hook may be overridden to create more than one
- * <mxImageShape> for creating new connections, but the default implementation
- * supports one image and is used as follows:
- * 
- * In order to display the "connect image" whenever the mouse is over the cell,
- * an DEFAULT_HOTSPOT of 1 should be used:
- * 
- * (code)
- * mxConstants.DEFAULT_HOTSPOT = 1;
- * (end)
- * 
- * In order to avoid confusion with the highlighting, the highlight color
- * should not be used with a connect image:
- * 
- * (code)
- * mxConstants.HIGHLIGHT_COLOR = null;
- * (end)
- * 
- * To install the image, the connectImage field of the mxConnectionHandler must
- * be assigned a new <mxImage> instance:
- * 
- * (code)
- * mxConnectionHandler.prototype.connectImage = new mxImage('images/green-dot.gif', 14, 14);
- * (end)
- * 
- * This will use the green-dot.gif with a width and height of 14 pixels as the
- * image to trigger new connections. In createIcons the icon field of the
- * handler will be set in order to remember the icon that has been clicked for
- * creating the new connection. This field will be available under selectedIcon
- * in the connect method, which may be overridden to take the icon that
- * triggered the new connection into account. This is useful if more than one
- * icon may be used to create a connection.
- *
- * Group: Events
- * 
- * Event: mxEvent.START
- * 
- * Fires when a new connection is being created by the user. The <code>state</code>
- * property contains the state of the source cell.
- * 
- * Event: mxEvent.CONNECT
- * 
- * Fires between begin- and endUpdate in <connect>. The <code>cell</code>
- * property contains the inserted edge, the <code>event</code> and <code>target</code> 
- * properties contain the respective arguments that were passed to <connect> (where
- * target corresponds to the dropTarget argument).
- * 
- * Note that the target is the cell under the mouse where the mouse button was released.
- * Depending on the logic in the handler, this doesn't necessarily have to be the target
- * of the inserted edge. To print the source, target or any optional ports IDs that the
- * edge is connected to, the following code can be used. To get more details about the
- * actual connection point, <mxGraph.getConnectionConstraint> can be used. To resolve
- * the port IDs, use <mxGraphModel.getCell>.
- * 
- * (code)
- * graph.connectionHandler.addListener(mxEvent.CONNECT, function(sender, evt)
- * {
- *   var edge = evt.getProperty('cell');
- *   var source = graph.getModel().getTerminal(edge, true);
- *   var target = graph.getModel().getTerminal(edge, false);
- *   
- *   var style = graph.getCellStyle(edge);
- *   var sourcePortId = style[mxConstants.STYLE_SOURCE_PORT];
- *   var targetPortId = style[mxConstants.STYLE_TARGET_PORT];
- *   
- *   mxLog.show();
- *   mxLog.debug('connect', edge, source.id, target.id, sourcePortId, targetPortId);
- * });
- * (end)
- *
- * Event: mxEvent.RESET
- * 
- * Fires when the <reset> method is invoked.
- *
- * Constructor: mxConnectionHandler
- *
- * Constructs an event handler that connects vertices using the specified
- * factory method to create the new edges. Modify
- * <mxConstants.ACTIVE_REGION> to setup the region on a cell which triggers
- * the creation of a new connection or use connect icons as explained
- * above.
- * 
- * Parameters:
- *

- * (code)
- * mxEdgeHandler.prototype.addEnabled = true;
- * mxEdgeHandler.prototype.removeEnabled = true;
- * (end)
- * 
- * Note: This experimental feature is not recommended for production use.
- * 
- * Constructor: mxEdgeHandler
- *
- * Constructs an edge handler for the specified <mxCellState>.
- * 
- * Parameters:
- * 
- * state - <mxCellState> of the cell to be handled.

-/**
- * Class: mxKeyHandler
- *
- * Event handler that listens to keystroke events. This is not a singleton,
- * however, it is normally only required once if the target is the document
- * element (default).
- * 
- * This handler installs a key event listener in the topmost DOM node and
- * processes all events that originate from descandants of <mxGraph.container>
- * or from the topmost DOM node. The latter means that all unhandled keystrokes
- * are handled by this object regardless of the focused state of the <graph>.
- * 
- * Example:
- * 
- * The following example creates a key handler that listens to the delete key
- * (46) and deletes the selection cells if the graph is enabled.
- * 
- * (code)
- * var keyHandler = new mxKeyHandler(graph);
- * keyHandler.bindKey(46, function(evt)
- * {
- *   if (graph.isEnabled())
- *   {
- *     graph.removeCells();
- *   }
- * });
- * (end)
- * 
- * Keycodes:
- * 
- * See http://tinyurl.com/yp8jgl or http://tinyurl.com/229yqw for a list of
- * keycodes or install a key event listener into the document element and print
- * the key codes of the respective events to the console.
- * 
- * To support the Command key and the Control key on the Mac, the following
- * code can be used.
- *
- * (code)
- * keyHandler.getFunction = function(evt)
- * {
- *   if (evt != null)
- *   {
- *     return (mxEvent.isControlDown(evt) || (mxClient.IS_MAC && evt.metaKey)) ? this.controlKeys[evt.keyCode] : this.normalKeys[evt.keyCode];
- *   }
- *   
- *   return null;
- * };
- * (end)
- * 
- * Constructor: mxKeyHandler
- *
- * Constructs an event handler that executes functions bound to specific
- * keystrokes.
- * 
- * Parameters:
- * 
- * graph - Reference to the associated <mxGraph>.
- * target - Optional reference to the event target. If null, the document
- * element is used as the event target, that is, the object where the key
- * event listener is installed.

-Document: API Specification
-
-Overview:
-
-  This JavaScript library is divided into 8 packages. The top-level <mxClient>
-  class includes (or dynamically imports) everything else. The current version
-  is stored in <mxClient.VERSION>.
-
-  The *editor* package provides the classes required to implement a diagram
-  editor. The main class in this package is <mxEditor>.
-  
-  The *view* and *model* packages implement the graph component, represented
-  by <mxGraph>. It refers to a <mxGraphModel> which contains <mxCell>s and
-  caches the state of the cells in a <mxGraphView>. The cells are painted
-  using a <mxCellRenderer> based on the appearance defined in <mxStylesheet>.
-  Undo history is implemented in <mxUndoManager>. To display an icon on the
-  graph, <mxCellOverlay> may be used. Validation rules are defined with
-  <mxMultiplicity>.
-  
-  The *handler*, *layout* and *shape* packages contain event listeners,
-  layout algorithms and shapes, respectively. The graph event listeners
-  include <mxRubberband> for rubberband selection, <mxTooltipHandler>
-  for tooltips and <mxGraphHandler> for  basic cell modifications.
-  <mxCompactTreeLayout> implements a tree layout algorithm, and the 
-  shape package provides various shapes, which are subclasses of
-  <mxShape>.
-  
-  The *util* package provides utility classes including <mxClipboard> for
-  copy-paste, <mxDatatransfer> for drag-and-drop, <mxConstants> for keys and
-  values of stylesheets, <mxEvent> and <mxUtils> for cross-browser
-  event-handling and general purpose functions, <mxResources> for
-  internationalization and <mxLog> for console output.
-
-  The *io* package implements a generic <mxObjectCodec> for turning
-  JavaScript objects into XML. The main class is <mxCodec>.
-  <mxCodecRegistry> is the global registry for custom codecs.
-  
-Events:
-
-  There are three different types of events, namely native DOM events,
-  <mxEventObjects> which are fired in an <mxEventSource>, and <mxMouseEvents>
-  which are fired in <mxGraph>.
-
-  Some helper methods for handling native events are provided in <mxEvent>. It
-  also takes care of resolving cycles between DOM nodes and JavaScript event
-  handlers, which can lead to memory leaks in IE6.
-  
-  Most custom events in mxGraph are implemented using <mxEventSource>. Its
-  listeners are functions that take a sender and <mxEventObject>. Additionally,
-  the <mxGraph> class fires special <mxMouseEvents> which are handled using
-  mouse listeners, which are objects that provide a mousedown, mousemove and
-  mouseup method.
-  
-  Events in <mxEventSource> are fired using <mxEventSource.fireEvent>.
-  Listeners are added and removed using <mxEventSource.addListener> and
-  <mxEventSource.removeListener>. <mxMouseEvents> in <mxGraph> are fired using
-  <mxGraph.fireMouseEvent>. Listeners are added and removed using
-  <mxGraph.addMouseListener> and <mxGraph.removeMouseListener>, respectively.
-  
-Key bindings:
-  
-  The following key bindings are defined for mouse events in the client across
-  all browsers and platforms:
-  
-  - Control-Drag: Duplicates (clones) selected cells
-  - Shift-Rightlick: Shows the context menu
-  - Alt-Click: Forces rubberband (aka. marquee)
-  - Control-Select: Toggles the selection state
-  - Shift-Drag: Constrains the offset to one direction
-  - Shift-Control-Drag: Panning (also Shift-Rightdrag)
-  
-Configuration:
-
-  The following global variables may be defined before the client is loaded to
-  specify its language or base path, respectively.
-  
-  - mxBasePath: Specifies the path in <mxClient.basePath>.
-  - mxImageBasePath: Specifies the path in <mxClient.imageBasePath>.
-  - mxLanguage: Specifies the language for resources in <mxClient.language>.
-  - mxDefaultLanguage: Specifies the default language in <mxClient.defaultLanguage>.
-  - mxLoadResources: Specifies if any resources should be loaded. Default is true.
-  - mxLoadStylesheets: Specifies if any stylesheets should be loaded. Default is true.
-
-Reserved Words:
-
-  The mx prefix is used for all classes and objects in mxGraph. The mx prefix
-  can be seen as the global namespace for all JavaScript code in mxGraph. The
-  following fieldnames should not be used in objects.
-  
-  - *mxObjectId*: If the object is used with mxObjectIdentity
-  - *as*: If the object is a field of another object
-  - *id*: If the object is an idref in a codec
-  - *mxListenerList*: Added to DOM nodes when used with <mxEvent>
-  - *window._mxDynamicCode*: Temporarily used to load code in Safari and Chrome
-  (see <mxClient.include>).
-  - *_mxJavaScriptExpression*: Global variable that is temporarily used to
-  evaluate code in Safari, Opera, Firefox 3 and IE (see <mxUtils.eval>).
-
-Files:
-
-  The library contains these relative filenames. All filenames are relative
-  to <mxClient.basePath>.
-  
-Built-in Images:
-  
-  All images are loaded from the <mxClient.imageBasePath>, 
-  which you can change to reflect your environment. The image variables can 
-  also be changed individually.
-  
-  - mxGraph.prototype.collapsedImage
-  - mxGraph.prototype.expandedImage
-  - mxGraph.prototype.warningImage
-  - mxWindow.prototype.closeImage
-  - mxWindow.prototype.minimizeImage
-  - mxWindow.prototype.normalizeImage
-  - mxWindow.prototype.maximizeImage
-  - mxWindow.prototype.resizeImage
-  - mxPopupMenu.prototype.submenuImage
-  - mxUtils.errorImage
-  - mxConstraintHandler.prototype.pointImage
-
-  The basename of the warning image (images/warning without extension) used in 
-  <mxGraph.setCellWarning> is defined in <mxGraph.warningImage>.
-
-Resources:
-  
-  The <mxEditor> and <mxGraph> classes add the following resources to
-  <mxResources> at class loading time:
-
-  - resources/editor*.properties
-  - resources/graph*.properties
-  
-  By default, the library ships with English and German resource files.
-
-Images:
-
-  Recommendations for using images. Use GIF images (256 color palette) in HTML
-  elements (such as the toolbar and context menu), and PNG images (24 bit) for
-  all images which appear inside the graph component.
-  
-  - For PNG images inside HTML elements, Internet Explorer will ignore any 
-    transparency information.
-  - For GIF images inside the graph, Firefox on the Mac will display strange 
-    colors. Furthermore, only the first image for animated GIFs is displayed 
-    on the Mac.
-    
-  For faster image rendering during application runtime, images can be
-  prefetched using the following code:
-  
-  (code)
-  var image = new Image();
-  image.src = url_to_image;
-  (end)
-
-Deployment:
-
-  The client is added to the page using the following script tag inside the
-  head of a document:
-
-  (code)
-  <script type="text/javascript" src="js/mxClient.js"></script>
-  (end)
-
-  The deployment version of the mxClient.js file contains all required code
-  in a single file. For deployment, the complete javascript/src directory is
-  required.
-  
-Source Code:
-
-  If you are a source code customer and you wish to develop using the 
-  full source code, the commented source code is shipped in the 
-  javascript/devel/source.zip file. It contains one file for each class 
-  in mxGraph. To use the source code the source.zip file must be 
-  uncompressed and the mxClient.js URL in the HTML  page must be changed 
-  to reference the uncompressed mxClient.js from the source.zip file.
-
-Compression:
- 
-  When using Apache2 with mod_deflate, you can use the following directive
-  in src/js/.htaccess to speedup the loading of the JavaScript sources:
-  
-  (code)
-  SetOutputFilter DEFLATE
-  (end)
-
-Classes:
-  
-  There are two types of "classes" in mxGraph: classes and singletons (where
-  only one instance exists). Singletons are mapped to global objects where the
-  variable name equals the classname. For example mxConstants is an object with
-  all the constants defined as object fields. Normal classes are mapped to a
-  constructor function and a prototype which defines the instance fields and
-  methods. For example, <mxEditor> is a function and mxEditor.prototype is the
-  prototype for the object that the mxEditor function creates. The mx prefix is
-  a convention that is used for all classes in the mxGraph package to avoid
-  conflicts with other objects in the global namespace.
-
-Subclassing:
-
-  For subclassing, the superclass must provide a constructor that is either
-  parameterless or handles an invocation with no arguments. Furthermore, the
-  special constructor field must be redefined after extending the prototype.
-  For example, the superclass of mxEditor is <mxEventSource>. This is
-  represented in JavaScript by first "inheriting" all fields and methods from
-  the superclass by assigning the prototype to an instance of the superclass,
-  eg. mxEditor.prototype = new mxEventSource() and redefining the constructor
-  field using mxEditor.prototype.constructor = mxEditor. The latter rule is
-  applied so that the type of an object can be retrieved via the name of it’s
-  constructor using mxUtils.getFunctionName(obj.constructor).
-
-Constructor:
-
-  For subclassing in mxGraph, the same scheme should be applied. For example,
-  for subclassing the <mxGraph> class, first a constructor must be defined for
-  the new class. The constructor calls the super constructor with any arguments
-  that it may have using the call function on the mxGraph function object,
-  passing along explitely each argument:
-
-  (code)
-  function MyGraph(container)
-  {
-    mxGraph.call(this, container);
-  }
-  (end)
-  
-  The prototype of MyGraph inherits from mxGraph as follows. As usual, the
-  constructor is redefined after extending the superclass:
-
-  (code)
-  MyGraph.prototype = new mxGraph();
-  MyGraph.prototype.constructor = MyGraph;
-  (end)
-  
-  You may want to define the codec associated for the class after the above
-  code. This code will be executed at class loading time and makes sure the
-  same codec is used to encode instances of mxGraph and MyGraph.
-
-  (code)
-  var codec = mxCodecRegistry.getCodec(mxGraph);
-  codec.template = new MyGraph();
-  mxCodecRegistry.register(codec);
-  (end)
-  
-Functions:
-
-  In the prototype for MyGraph, functions of mxGraph can then be extended as
-  follows.
-  
-  (code)
-  MyGraph.prototype.isCellSelectable = function(cell)
-  {
-    var selectable = mxGraph.prototype.isSelectable.apply(this, arguments);
-
-    var geo = this.model.getGeometry(cell);
-    return selectable && (geo == null || !geo.relative);
-  }
-  (end)
-  
-  The supercall in the first line is optional. It is done using the apply
-  function on the isSelectable function object of the mxGraph prototype, using
-  the special this and arguments variables as parameters. Calls to the
-  superclass function are only possible if the function is not replaced in the
-  superclass as follows, which is another way of “subclassing” in JavaScript.
-
-  (code)
-  mxGraph.prototype.isCellSelectable = function(cell)
-  {
-    var geo = this.model.getGeometry(cell);
-    return selectable &&
-        (geo == null ||
-        !geo.relative);
-  }
-  (end)
-
-  The above scheme is useful if a function definition needs to be replaced
-  completely.
-  
-  In order to add new functions and fields to the subclass, the following code
-  is used. The example below adds a new function to return the XML
-  representation of the graph model:
-
-  (code)
-  MyGraph.prototype.getXml = function()
-  {
-    var enc = new mxCodec();
-    return enc.encode(this.getModel());
-  }
-  (end)
-  
-Variables:
-
-  Likewise, a new field is declared and defined as follows.
-
-  (code)
-  MyGraph.prototype.myField = 'Hello, World!';
-  (end)
-  
-  Note that the value assigned to myField is created only once, that is, all
-  instances of MyGraph share the same value. If you require instance-specific
-  values, then the field must be defined in the constructor instead.
-
-  (code)
-  function MyGraph(container)
-  {
-    mxGraph.call(this, container);
-    
-    this.myField = new Array();
-  }
-  (end)
-
-  Finally, a new instance of MyGraph is created using the following code, where
-  container is a DOM node that acts as a container for the graph view:
-
-  (code)
-  var graph = new MyGraph(container);
-  (end)

-/**
- * Class: mxCodec
- *
- * XML codec for JavaScript object graphs. See <mxObjectCodec> for a
- * description of the general encoding/decoding scheme. This class uses the
- * codecs registered in <mxCodecRegistry> for encoding/decoding each object.
- * 
- * References:
- * 
- * In order to resolve references, especially forward references, the mxCodec
- * constructor must be given the document that contains the referenced
- * elements.
- *
- * Examples:
- *
- * The following code is used to encode a graph model.
- *
- * (code)
- * var encoder = new mxCodec();
- * var result = encoder.encode(graph.getModel());
- * var xml = mxUtils.getXml(result);
- * (end)
- * 
- * Example:
- * 
- * Using the following code, the selection cells of a graph are encoded and the
- * output is displayed in a dialog box.
- * 
- * (code)
- * var enc = new mxCodec();
- * var cells = graph.getSelectionCells();
- * mxUtils.alert(mxUtils.getPrettyXml(enc.encode(cells)));
- * (end)
- * 
- * Newlines in the XML can be coverted to <br>, in which case a '<br>' argument
- * must be passed to <mxUtils.getXml> as the second argument.
- * 
- * Example:
- * 
- * Using the code below, an XML document is decodec into an existing model. The
- * document may be obtained using one of the functions in mxUtils for loading
- * an XML file, eg. <mxUtils.get>, or using <mxUtils.parseXml> for parsing an
- * XML string.
- * 
- * (code)
- * var decoder = new mxCodec(doc)
- * decoder.decode(doc.documentElement, graph.getModel());
- * (end)
- * 
- * Debugging:
- * 
- * For debugging i/o you can use the following code to get the sequence of
- * encoded objects:
- * 
- * (code)
- * var oldEncode = mxCodec.prototype.encode;
- * mxCodec.prototype.encode = function(obj)
- * {
- *   mxLog.show();
- *   mxLog.debug('mxCodec.encode: obj='+mxUtils.getFunctionName(obj.constructor));
- *   
- *   return oldEncode.apply(this, arguments);
- * };
- * (end)
- * 
- * Constructor: mxCodec
- *
- * Constructs an XML encoder/decoder for the specified
- * owner document.
- *
- * Parameters:
- *
- * document - Optional XML document that contains the data.
- * If no document is specified then a new document is created
- * using <mxUtils.createXmlDocument>.

-	 * separator - Adds a vertical separator. No attributes.
-	 * hr - Adds a horizontal separator. No attributes.

-	 * action - Name of the action to execute in enclosing editor.
-	 * mode - Modename (see below).
-	 * template - Template name for cell insertion.
-	 * style - Optional style to override the template style.
-	 * icon - Icon (relative/absolute URL).
-	 * pressedIcon - Optional icon for pressed state (relative/absolute URL).
-	 * id - Optional ID to be used for the created DOM element.
-	 * toggle - Optional 0 or 1 to disable toggling of the element. Default is
-	 * 1 (true).
-	 *
-	 * The action, mode and template attributes are mutually exclusive. The
-	 * style can only be used with the template attribute. The add node may
-	 * contain another sequence of add nodes with as and action attributes
-	 * to create a combo box in the toolbar. If the icon is specified then
-	 * a list of the child node is expected to have its template attribute
-	 * set and the action is ignored instead.
-	 * 
-	 * Nodes with a specified template may define a function to be used for
-	 * inserting the cloned template into the graph. Here is an example of such
-	 * a node:
-	 * 
-	 * (code)
-	 * <add as="Swimlane" template="swimlane" icon="images/swimlane.gif"><![CDATA[
-	 *   function (editor, cell, evt, targetCell)
-	 *   {
-	 *     var pt = mxUtils.convertPoint(
-	 *       editor.graph.container, mxEvent.getClientX(evt),
-	 *         mxEvent.getClientY(evt));
-	 *     return editor.addVertex(targetCell, cell, pt.x, pt.y);
-	 *   }
-	 * ]]></add>
-	 * (end)
-	 * 
-	 * In the above function, editor is the enclosing <mxEditor> instance, cell
-	 * is the clone of the template, evt is the mouse event that represents the
-	 * drop and targetCell is the cell under the mousepointer where the drop
-	 * occurred. The targetCell is retrieved using <mxGraph.getCellAt>.
-	 *
-	 * Futhermore, nodes with the mode attribute may define a function to
-	 * be executed upon selection of the respective toolbar icon. In the
-	 * example below, the default edge style is set when this specific
-	 * connect-mode is activated:
-	 *
-	 * (code)
-	 * <add as="connect" mode="connect"><![CDATA[
-	 *   function (editor)
-	 *   {
-	 *     if (editor.defaultEdge != null)
-	 *     {
-	 *       editor.defaultEdge.style = 'straightEdge';
-	 *     }
-	 *   }
-	 * ]]></add>
-	 * (end)
-	 *
-	 * Modes:
-	 *
-	 * select - Left mouse button used for rubberband- & cell-selection.
-	 * connect - Allows connecting vertices by inserting new edges.
-	 * pan - Disables selection and switches to panning on the left button.
-	 *
-	 * Example:
-	 *
-	 * To add items to the toolbar:
-	 * 
-	 * (code)
-	 * <mxDefaultToolbar as="toolbar">
-	 *   <add as="save" action="save" icon="images/save.gif"/>
-	 *   <br/><hr/>

-	 * width - Width for the new window.
-	 * height - Optional height for the new window.
-	 * name - Name of the stylesheet (absolute/relative URL).
-	 * basename - Basename of the resource bundle (see <mxResources>).
-	 *
-	 * The x, y, width and height attributes are used to create a new

-	 * toolbar - Toolbar element (see <mxEditor.setToolbarContainer>).
-	 * status - Status bar element (see <mxEditor.setStatusContainer>).
-	 *
-	 * Example:
-	 *
-	 * (code)
-	 * <ui>
-	 *   <stylesheet name="css/process.css"/>

-/**
- * Class: mxObjectCodec
- *
- * Generic codec for JavaScript objects that implements a mapping between
- * JavaScript objects and XML nodes that maps each field or element to an
- * attribute or child node, and vice versa.
- * 
- * Atomic Values:
- * 
- * Consider the following example.
- * 
- * (code)
- * var obj = new Object();
- * obj.foo = "Foo";
- * obj.bar = "Bar";
- * (end)
- * 
- * This object is encoded into an XML node using the following.
- * 
- * (code)
- * var enc = new mxCodec();
- * var node = enc.encode(obj);
- * (end)
- * 
- * The output of the encoding may be viewed using <mxLog> as follows.
- * 
- * (code)
- * mxLog.show();
- * mxLog.debug(mxUtils.getPrettyXml(node));
- * (end)
- * 
- * Finally, the result of the encoding looks as follows.
- * 
- * (code)
- * <Object foo="Foo" bar="Bar"/>
- * (end)
- * 
- * In the above output, the foo and bar fields have been mapped to attributes
- * with the same names, and the name of the constructor was used for the
- * nodename.
- * 
- * Booleans:
- *
- * Since booleans are numbers in JavaScript, all boolean values are encoded
- * into 1 for true and 0 for false. The decoder also accepts the string true
- * and false for boolean values.
- * 
- * Objects:
- * 
- * The above scheme is applied to all atomic fields, that is, to all non-object
- * fields of an object. For object fields, a child node is created with a
- * special attribute that contains the fieldname. This special attribute is
- * called "as" and hence, as is a reserved word that should not be used for a
- * fieldname.
- * 
- * Consider the following example where foo is an object and bar is an atomic
- * property of foo.
- * 
- * (code)
- * var obj = {foo: {bar: "Bar"}};
- * (end)
- * 
- * This will be mapped to the following XML structure by mxObjectCodec.
- * 
- * (code)
- * <Object>
- *   <Object bar="Bar" as="foo"/>
- * </Object>
- * (end)
- * 
- * In the above output, the inner Object node contains the as-attribute that
- * specifies the fieldname in the enclosing object. That is, the field foo was
- * mapped to a child node with an as-attribute that has the value foo.
- * 
- * Arrays:
- * 
- * Arrays are special objects that are either associative, in which case each
- * key, value pair is treated like a field where the key is the fieldname, or
- * they are a sequence of atomic values and objects, which is mapped to a
- * sequence of child nodes. For object elements, the above scheme is applied
- * without the use of the special as-attribute for creating each child. For
- * atomic elements, a special add-node is created with the value stored in the
- * value-attribute.
- * 
- * For example, the following array contains one atomic value and one object
- * with a field called bar. Furthermore it contains two associative entries
- * called bar with an atomic value, and foo with an object value.
- * 
- * (code)
- * var obj = ["Bar", {bar: "Bar"}];
- * obj["bar"] = "Bar";
- * obj["foo"] = {bar: "Bar"};
- * (end)
- * 
- * This array is represented by the following XML nodes.
- * 
- * (code)
- * <Array bar="Bar">
- *   <add value="Bar"/>
- *   <Object bar="Bar"/>
- *   <Object bar="Bar" as="foo"/>
- * </Array>
- * (end)
- * 
- * The Array node name is the name of the constructor. The additional
- * as-attribute in the last child contains the key of the associative entry,
- * whereas the second last child is part of the array sequence and does not
- * have an as-attribute.
- * 
- * References:
- * 
- * Objects may be represented as child nodes or attributes with ID values,
- * which are used to lookup the object in a table within <mxCodec>. The
- * <isReference> function is in charge of deciding if a specific field should
- * be encoded as a reference or not. Its default implementation returns true if
- * the fieldname is in <idrefs>, an array of strings that is used to configure
- * the <mxObjectCodec>.
- * 
- * Using this approach, the mapping does not guarantee that the referenced
- * object itself exists in the document. The fields that are encoded as
- * references must be carefully chosen to make sure all referenced objects
- * exist in the document, or may be resolved by some other means if necessary.
- * 
- * For example, in the case of the graph model all cells are stored in a tree
- * whose root is referenced by the model's root field. A tree is a structure
- * that is well suited for an XML representation, however, the additional edges
- * in the graph model have a reference to a source and target cell, which are
- * also contained in the tree. To handle this case, the source and target cell
- * of an edge are treated as references, whereas the children are treated as
- * objects. Since all cells are contained in the tree and no edge references a
- * source or target outside the tree, this setup makes sure all referenced
- * objects are contained in the document.
- * 
- * In the case of a tree structure we must further avoid infinite recursion by
- * ignoring the parent reference of each child. This is done by returning true
- * in <isExcluded>, whose default implementation uses the array of excluded
- * fieldnames passed to the mxObjectCodec constructor.
- * 
- * References are only used for cells in mxGraph. For defining other
- * referencable object types, the codec must be able to work out the ID of an
- * object. This is done by implementing <mxCodec.reference>. For decoding a
- * reference, the XML node with the respective id-attribute is fetched from the
- * document, decoded, and stored in a lookup table for later reference. For
- * looking up external objects, <mxCodec.lookup> may be implemented.
- * 
- * Expressions:
- * 
- * For decoding JavaScript expressions, the add-node may be used with a text
- * content that contains the JavaScript expression. For example, the following
- * creates a field called foo in the enclosing object and assigns it the value
- * of <mxConstants.ALIGN_LEFT>.
- * 
- * (code)
- * <Object>
- *   <add as="foo">mxConstants.ALIGN_LEFT</add>
- * </Object>
- * (end)

- * The resulting object has a field called foo with the value "left". Its XML

- * 
- * (code)
- * <Object foo="left"/>
- * (end)
- * 
- * This means the expression is evaluated at decoding time and the result of
- * the evaluation is stored in the respective field. Valid expressions are all
- * JavaScript expressions, including function definitions, which are mapped to
- * functions on the resulting object.
- * 
- * Constructor: mxObjectCodec
- *
- * Constructs a new codec for the specified template object.
- * The variables in the optional exclude array are ignored by
- * the codec. Variables in the optional idrefs array are
- * turned into references in the XML. The optional mapping
- * may be used to map from variable names to XML attributes.
- * The argument is created as follows:
- *
- * (code)
- * var mapping = new Object();
- * mapping['variableName'] = 'attribute-name';
- * (end)
- *
- * Parameters:
- *
- * template - Prototypical instance of the object to be
- * encoded/decoded.
- * exclude - Optional array of fieldnames to be ignored.
- * idrefs - Optional array of fieldnames to be converted to/from
- * references.
- * mapping - Optional mapping from field- to attributenames.

-/**
- * Class: mxGeometry
- * 
- * Extends <mxRectangle> to represent the geometry of a cell.
- * 
- * For vertices, the geometry consists of the x- and y-location, and the width
- * and height. For edges, the geometry consists of the optional terminal- and
- * control points. The terminal points are only required if an edge is
- * unconnected, and are stored in the sourcePoint> and <targetPoint>
- * variables, respectively.
- * 
- * Example:
- * 
- * If an edge is unconnected, that is, it has no source or target terminal,
- * then a geometry with terminal points for a new edge can be defined as
- * follows.
- * 
- * (code)
- * geometry.setTerminalPoint(new mxPoint(x1, y1), true);
- * geometry.points = [new mxPoint(x2, y2)];
- * geometry.setTerminalPoint(new mxPoint(x3, y3), false);
- * (end)
- * 
- * Control points are used regardless of the connected state of an edge and may
- * be ignored or interpreted differently depending on the edge's <mxEdgeStyle>.
- * 
- * To disable automatic reset of control points after a cell has been moved or
- * resized, the the <mxGraph.resizeEdgesOnMove> and
- * <mxGraph.resetEdgesOnResize> may be used.
- *
- * Edge Labels:
- * 
- * Using the x- and y-coordinates of a cell's geometry, it is possible to
- * position the label on edges on a specific location on the actual edge shape
- * as it appears on the screen. The x-coordinate of an edge's geometry is used
- * to describe the distance from the center of the edge from -1 to 1 with 0
- * being the center of the edge and the default value. The y-coordinate of an
- * edge's geometry is used to describe the absolute, orthogonal distance in
- * pixels from that point. In addition, the <mxGeometry.offset> is used as an
- * absolute offset vector from the resulting point.
- * 
- * This coordinate system is applied if <relative> is true, otherwise the
- * offset defines the absolute vector from the edge's center point to the
- * label.
- * 
- * Ports:
- * 
- * The term "port" refers to a relatively positioned, connectable child cell,
- * which is used to specify the connection between the parent and another cell
- * in the graph. Ports are typically modeled as vertices with relative
- * geometries.
- * 
- * Offsets:
- * 
- * The <offset> field is interpreted in 3 different ways, depending on the cell
- * and the geometry. For edges, the offset defines the absolute offset for the
- * edge label. For relative geometries, the offset defines the absolute offset
- * for the origin (top, left corner) of the vertex, otherwise the offset
- * defines the absolute offset for the label inside the vertex or group.
- * 
- * Constructor: mxGeometry
- *
- * Constructs a new object to describe the size and location of a vertex or
- * the control points of an edge.

-/**
- * Class: mxGraphModel
- * 
- * Extends <mxEventSource> to implement a graph model. The graph model acts as
- * a wrapper around the cells which are in charge of storing the actual graph
- * datastructure. The model acts as a transactional wrapper with event
- * notification for all changes, whereas the cells contain the atomic
- * operations for updating the actual datastructure.
- * 
- * Layers:
- * 
- * The cell hierarchy in the model must have a top-level root cell which
- * contains the layers (typically one default layer), which in turn contain the
- * top-level cells of the layers. This means each cell is contained in a layer.
- * If no layers are required, then all new cells should be added to the default
- * layer.
- * 
- * Layers are useful for hiding and showing groups of cells, or for placing
- * groups of cells on top of other cells in the display. To identify a layer,
- * the <isLayer> function is used. It returns true if the parent of the given
- * cell is the root of the model.
- * 
- * Encoding the model:
- * 
- * To encode a graph model, use the following code:
- * 
- * (code)
- * var enc = new mxCodec();
- * var node = enc.encode(graph.getModel());
- * (end)
- * 
- * This will create an XML node that contains all the model information.
- * 
- * Encoding and decoding changes:
- * 
- * For the encoding of changes, a graph model listener is required that encodes
- * each change from the given array of changes.
- * 
- * (code)
- * model.addListener(mxEvent.CHANGE, function(sender, evt)
- * {
- *   var changes = evt.getProperty('edit').changes;
- *   var nodes = [];
- *   var codec = new mxCodec();
- * 
- *   for (var i = 0; i < changes.length; i++)
- *   {
- *     nodes.push(codec.encode(changes[i]));
- *   }
- *   // do something with the nodes
- * });
- * (end)
- * 
- * For the decoding and execution of changes, the codec needs a lookup function
- * that allows it to resolve cell IDs as follows:
- * 
- * (code)
- * var codec = new mxCodec();
- * codec.lookup = function(id)
- * {
- *   return model.getCell(id);
- * }
- * (end)
- * 
- * For each encoded change (represented by a node), the following code can be
- * used to carry out the decoding and create a change object.
- * 
- * (code)
- * var changes = [];
- * var change = codec.decode(node);
- * change.model = model;
- * change.execute();
- * changes.push(change);
- * (end)
- * 
- * The changes can then be dispatched using the model as follows.
- * 
- * (code)
- * var edit = new mxUndoableEdit(model, false);
- * edit.changes = changes;
- * 
- * edit.notify = function()
- * {
- *   edit.source.fireEvent(new mxEventObject(mxEvent.CHANGE,
- *   	'edit', edit, 'changes', edit.changes));
- *   edit.source.fireEvent(new mxEventObject(mxEvent.NOTIFY,
- *   	'edit', edit, 'changes', edit.changes));
- * }
- * 
- * model.fireEvent(new mxEventObject(mxEvent.UNDO, 'edit', edit));
- * model.fireEvent(new mxEventObject(mxEvent.CHANGE,
- * 		'edit', edit, 'changes', changes));
- * (end)
- *
- * Event: mxEvent.CHANGE
- *
- * Fires when an undoable edit is dispatched. The <code>edit</code> property
- * contains the <mxUndoableEdit>. The <code>changes</code> property contains
- * the array of atomic changes inside the undoable edit. The changes property
- * is <strong>deprecated</strong>, please use edit.changes instead.
- *
- * Example:
- * 
- * For finding newly inserted cells, the following code can be used:
- * 
- * (code)
- * graph.model.addListener(mxEvent.CHANGE, function(sender, evt)
- * {
- *   var changes = evt.getProperty('edit').changes;
- * 
- *   for (var i = 0; i < changes.length; i++)
- *   {
- *     var change = changes[i];
- *     
- *     if (change instanceof mxChildChange &&
- *       change.change.previous == null)
- *     {
- *       graph.startEditingAtCell(change.child);
- *       break;
- *     }
- *   }
- * });
- * (end)
- * 
- * 
- * Event: mxEvent.NOTIFY
- *
- * Same as <mxEvent.CHANGE>, this event can be used for classes that need to
- * implement a sync mechanism between this model and, say, a remote model. In
- * such a setup, only local changes should trigger a notify event and all
- * changes should trigger a change event.
- * 
- * Event: mxEvent.EXECUTE
- * 
- * Fires between begin- and endUpdate and after an atomic change was executed
- * in the model. The <code>change</code> property contains the atomic change
- * that was executed.
- *
- * Event: mxEvent.BEGIN_UPDATE
- *
- * Fires after the <updateLevel> was incremented in <beginUpdate>. This event
- * contains no properties.
- * 
- * Event: mxEvent.END_UPDATE
- * 
- * Fires after the <updateLevel> was decreased in <endUpdate> but before any
- * notification or change dispatching. The <code>edit</code> property contains
- * the <currentEdit>.
- * 
- * Event: mxEvent.BEFORE_UNDO
- * 
- * Fires before the change is dispatched after the update level has reached 0
- * in <endUpdate>. The <code>edit</code> property contains the <curreneEdit>.
- * 
- * Event: mxEvent.UNDO
- * 
- * Fires after the change was dispatched in <endUpdate>. The <code>edit</code>
- * property contains the <currentEdit>.
- * 
- * Constructor: mxGraphModel
- * 
- * Constructs a new graph model. If no root is specified then a new root
- * <mxCell> with a default layer is created.
- * 
- * Parameters:
- * 
- * root - <mxCell> that represents the root cell.

-/**
- * Class: mxShape
- *
- * Base class for all shapes. A shape in mxGraph is a
- * separate implementation for SVG, VML and HTML. Which
- * implementation to use is controlled by the <dialect>
- * property which is assigned from within the <mxCellRenderer>
- * when the shape is created. The dialect must be assigned
- * for a shape, and it does normally depend on the browser and
- * the confiuration of the graph (see <mxGraph> rendering hint).
- *
- * For each supported shape in SVG and VML, a corresponding
- * shape exists in mxGraph, namely for text, image, rectangle,
- * rhombus, ellipse and polyline. The other shapes are a
- * combination of these shapes (eg. label and swimlane)
- * or they consist of one or more (filled) path objects
- * (eg. actor and cylinder). The HTML implementation is
- * optional but may be required for a HTML-only view of
- * the graph.
- *
- * Custom Shapes:
- *
- * To extend from this class, the basic code looks as follows.
- * In the special case where the custom shape consists only of
- * one filled region or one filled region and an additional stroke
- * the <mxActor> and <mxCylinder> should be subclassed,
- * respectively. These implement <redrawPath> in order to create
- * the path expression for VML and SVG via a unified API (see
- * <mxPath>). <mxCylinder.redrawPath> has an additional boolean
- * argument to draw the foreground and background separately.
- *
- * (code)
- * function CustomShape() { }
- * 
- * CustomShape.prototype = new mxShape();
- * CustomShape.prototype.constructor = CustomShape; 
- * (end)
- *
- * To register a custom shape in an existing graph instance,
- * one must register the shape under a new name in the graph's
- * cell renderer as follows:
- *
- * (code)
- * graph.cellRenderer.registerShape('customShape', CustomShape);
- * (end)
- *
- * The second argument is the name of the constructor.
- *
- * In order to use the shape you can refer to the given name above
- * in a stylesheet. For example, to change the shape for the default
- * vertex style, the following code is used:
- *
- * (code)
- * var style = graph.getStylesheet().getDefaultVertexStyle();
- * style[mxConstants.STYLE_SHAPE] = 'customShape';
- * (end)

-/**
- * Class: mxStencil
- *
- * Implements a generic shape which is based on a XML node as a description.
- * The node contains a background and a foreground node, which contain the
- * definition to render the respective part of the shape. Note that the
- * fill, stroke or fillstroke of the background is be the first statement
- * of the foreground. This is because the content of the background node
- * maybe used to not only render the shape itself, but also its shadow and
- * other elements which do not require a fill, stroke or fillstroke.
- * 
- * The shape uses a coordinate system with a width of 100 and a height of
- * 100 by default. This can be changed by setting the w and h attribute of
- * the shape element. The aspect attribute can be set to "variable" (default)
- * or "fixed". If fixed is used, then the aspect which is defined via the w
- * and h attribute is kept constant while the shape is scaled.
- * 
- * The possible contents of the background and foreground elements are rect,
- * ellipse, roundrect, text, image, include-shape or paths. A path element
- * contains move, line, curve, quad, arc and close elements. The rect, ellipse
- * and roundrect elements may be thought of as special path elements. All these
- * path elements must be followed by either fill, stroke or fillstroke (note
- * that text, image and include-shape or not path elements).
- * 
- * The background element can be empty or contain at most one path element. It
- * should not contain a text, image or include-shape element. If the background
- * element is empty, then no shadow or glass effect will be rendered. If the
- * background element is non-empty, then the corresponding fill, stroke or
- * fillstroke should be the first element in the subsequent foreground element.
- *  
- * The format of the XML is "a simplified HTML 5 Canvas". Each command changes
- * the "current" state, so eg. a linecap, linejoin will be used for all
- * subsequent line drawing, unless a save/restore appears, which saves/restores
- * a state in a stack.
- * 
- * The connections section contains the fixed connection points for a stencil.
- * The perimeter attribute of the constraint element should have a value of 0
- * or 1 (default), where 1 (true) specifies that the given point should be
- * projected into the perimeter of the given shape.
- * 
- * The x- and y-coordinates are typically between 0 and 1 and define the
- * location of the connection point relative to the width and height of the
- * shape.
- * 
- * The dashpattern directive sets the current dashpattern. The format for the
- * pattern attribute is a space-separated sequence of numbers, eg. 5 5 5 5,
- * that specifies the lengths of alternating dashes and spaces in dashed lines.
- * The dashpattern should be used together with the dashed directive to
- * enabled/disable the dashpattern. The default dashpattern is 3 3.
- * 
- * The strokewidth attribute defines a fixed strokewidth for the shape. It
- * can contain a numeric value or the keyword "inherit", which means that the
- * strokeWidth from the cell's style will be used and muliplied with the shape's
- * scale. If numeric values are used, those are multiplied with the minimum
- * scale used to render the stencil inside the shape's bounds.
- * 
- * Constructor: mxStencilShape
- * 
- * Constructs a new generic shape by setting <desc> to the given XML node and
- * invoking <parseDescription> and <parseConstraints>.
- * 
- * Parameters:
- * 
- * desc - XML node that contains the stencil description.

- * {
- *   return new mxPoint(-offset.y, offset.x);
- * };
- * (end)
- * 
- * Constructor: mxText
- *
- * Constructs a new text shape.
- * 
- * Parameters:
- * 
- * value - String that represents the text to be displayed. This is stored in
- * <value>.

- * fontStyle - Specifies the font style. Default is 0. This is stored in
- * <fontStyle>.
- * spacing - Integer that specifies the global spacing. Default is 2. This is
- * stored in <spacing>.
- * spacingTop - Integer that specifies the top spacing. Default is 0. The
- * sum of the spacing and this is stored in <spacingTop>.
- * spacingRight - Integer that specifies the right spacing. Default is 0. The
- * sum of the spacing and this is stored in <spacingRight>.
- * spacingBottom - Integer that specifies the bottom spacing. Default is 0.The
- * sum of the spacing and this is stored in <spacingBottom>.
- * spacingLeft - Integer that specifies the left spacing. Default is 0. The
- * sum of the spacing and this is stored in <spacingLeft>.
- * horizontal - Boolean that specifies if the label is horizontal. Default is
- * true. This is stored in <horizontal>.
- * background - String that specifies the background color. Default is null.
- * This is stored in <background>.
- * border - String that specifies the label border color. Default is null.
- * This is stored in <border>.
- * wrap - Specifies if word-wrapping should be enabled. Default is false.

-/**
- * Class: mxSession
- *
- * Session for sharing an <mxGraphModel> with other parties
- * via a backend that acts as a multicaster for all changes.
- * 
- * Diagram Sharing:
- * 
- * The diagram sharing is a mechanism where each atomic change of the model is
- * encoded into XML using <mxCodec> and then transmitted to the server by the
- * <mxSession> object. On the server, the XML data is dispatched to each
- * listener on the same diagram (except the sender), and the XML is decoded
- * back into atomic changes on the client side, which are then executed on the
- * model and stored in the command history.
- * 
- * The <mxSession.significantRemoteChanges> specifies how these changes are
- * treated with respect to undo: The default value (true) will undo the last
- * change regardless of whether it was a remote or a local change. If the
- * switch is false, then an undo will go back until the last local change,
- * silently undoing all remote changes up to that point. Note that these
- * changes will be added as new remote changes to the history of the other
- * clients.
- * 
- * Event: mxEvent.CONNECT
- *
- * Fires after the session has been started, that is, after the response to the
- * initial request was received and the session goes into polling mode. This
- * event has no properties.
- *
- * Event: mxEvent.SUSPEND
- *
- * Fires after <suspend> was called an the session was not already in suspended
- * state. This event has no properties.
- *
- * Event: mxEvent.RESUME
- *
- * Fires after the session was resumed in <resume>. This event has no
- * properties.
- *
- * Event: mxEvent.DISCONNECT
- *
- * Fires after the session was stopped in <stop>. The <code>reason</code>
- * property contains the optional exception that was passed to the stop method.
- *
- * Event: mxEvent.NOTIFY
- *
- * Fires after a notification was sent in <notify>. The <code>url</code>
- * property contains the URL and the <code>xml</code> property contains the XML
- * data of the request.
- *
- * Event: mxEvent.GET
- *
- * Fires after a response was received in <get>. The <code>url</code> property
- * contains the URL and the <code>request</code> is the <mxXmlRequest> that
- * contains the response.
- *
- * Event: mxEvent.FIRED
- * 
- * Fires after an array of edits has been executed on the model. The
- * <code>changes</code> property contains the array of changes.
- * 
- * Event: mxEvent.RECEIVE
- *
- * Fires after an XML node was received in <receive>. The <code>node</code>
- * property contains the node that was received.
- * 
- * Constructor: mxSession
- * 
- * Constructs a new session using the given <mxGraphModel> and URLs to
- * communicate with the backend.
- * 
- * Parameters:
- * 
- * model - <mxGraphModel> that contains the data.

-/**
- * Class: mxUndoManager
- *
- * Implements a command history. When changing the graph model, an
- * <mxUndoableChange> object is created at the start of the transaction (when
- * model.beginUpdate is called). All atomic changes are then added to this
- * object until the last model.endUpdate call, at which point the
- * <mxUndoableEdit> is dispatched in an event, and added to the history inside
- * <mxUndoManager>. This is done by an event listener in
- * <mxEditor.installUndoHandler>.
- * 
- * Each atomic change of the model is represented by an object (eg.
- * <mxRootChange>, <mxChildChange>, <mxTerminalChange> etc) which contains the
- * complete undo information. The <mxUndoManager> also listens to the
- * <mxGraphView> and stores it's changes to the current root as insignificant
- * undoable changes, so that drilling (step into, step up) is undone.
- * 
- * This means when you execute an atomic change on the model, then change the
- * current root on the view and click undo, the change of the root will be
- * undone together with the change of the model so that the display represents
- * the state at which the model was changed. However, these changes are not
- * transmitted for sharing as they do not represent a state change.
- *
- * Example:
- * 
- * When adding an undo manager to a graph, make sure to add it
- * to the model and the view as well to maintain a consistent
- * display across multiple undo/redo steps.
- *
- * (code)
- * var undoManager = new mxUndoManager();
- * var listener = function(sender, evt)
- * {
- *   undoManager.undoableEditHappened(evt.getProperty('edit'));
- * };
- * graph.getModel().addListener(mxEvent.UNDO, listener);
- * graph.getView().addListener(mxEvent.UNDO, listener);
- * (end)
- * 
- * The code creates a function that informs the undoManager
- * of an undoable edit and binds it to the undo event of
- * <mxGraphModel> and <mxGraphView> using
- * <mxEventSource.addListener>.
- * 
- * Event: mxEvent.CLEAR
- * 
- * Fires after <clear> was invoked. This event has no properties.
- * 
- * Event: mxEvent.UNDO
- * 
- * Fires afer a significant edit was undone in <undo>. The <code>edit</code>
- * property contains the <mxUndoableEdit> that was undone.
- * 
- * Event: mxEvent.REDO
- * 
- * Fires afer a significant edit was redone in <redo>. The <code>edit</code>
- * property contains the <mxUndoableEdit> that was redone.
- * 
- * Event: mxEvent.ADD
- * 
- * Fires after an undoable edit was added to the history. The <code>edit</code>
- * property contains the <mxUndoableEdit> that was added.
- * 
- * Constructor: mxUndoManager

-/**
- * 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)
- *
- * 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.

-/**
- * Class: mxXmlRequest
- * 
- * XML HTTP request wrapper. See also: <mxUtils.get>, <mxUtils.post> and
- * <mxUtils.load>. This class provides a cross-browser abstraction for Ajax
- * requests.
- * 
- * Encoding:
- * 
- * For encoding parameter values, the built-in encodeURIComponent JavaScript
- * method must be used. For automatic encoding of post data in <mxEditor> the
- * <mxEditor.escapePostData> switch can be set to true (default). The encoding
- * will be carried out using the conte type of the page. That is, the page
- * containting the editor should contain a meta tag in the header, eg.
- * <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
- * 
- * Example:
- * 
- * (code)
- * var onload = function(req)
- * {
- *   mxUtils.alert(req.getDocumentElement());
- * }
- * 
- * var onerror = function(req)
- * {
- *   mxUtils.alert(req.getStatus());
- * }
- * new mxXmlRequest(url, 'key=value').send(onload, onerror);
- * (end)
- * 
- * Sends an asynchronous POST request to the specified URL.
- * 
- * Example:
- * 
- * (code)
- * var req = new mxXmlRequest(url, 'key=value', 'POST', false);
- * req.send();
- * mxUtils.alert(req.getDocumentElement());
- * (end)
- * 
- * Sends a synchronous POST request to the specified URL.
- * 
- * Example:
- * 
- * (code)
- * var encoder = new mxCodec();
- * var result = encoder.encode(graph.getModel());
- * var xml = encodeURIComponent(mxUtils.getXml(result));
- * new mxXmlRequest(url, 'xml='+xml).send();
- * (end)
- * 
- * Sends an encoded graph model to the specified URL using xml as the
- * parameter name. The parameter can then be retrieved in C# as follows:
- * 
- * (code)
- * string xml = HttpUtility.UrlDecode(context.Request.Params["xml"]);
- * (end)
- * 
- * Or in Java as follows:
- * 
- * (code)
- * String xml = URLDecoder.decode(request.getParameter("xml"), "UTF-8").replace("\n", "&#xa;");
- * (end)
- *
- * Note that the linefeeds should only be replaced if the XML is
- * processed in Java, for example when creating an image.
- * 
- * Constructor: mxXmlRequest
- * 
- * Constructs an XML HTTP request.
- * 
- * Parameters:
- * 
- * url - Target URL of the request.
- * params - Form encoded parameters to send with a POST request.
- * method - String that specifies the request method. Possible values are
- * POST and GET. Default is POST.
- * async - Boolean specifying if an asynchronous request should be used.
- * Default is true.
- * username - String specifying the username to be used for the request.
- * password - String specifying the password to be used for the request.

-/**
- * Class: mxCellEditor
- *
- * In-place editor for the graph. To control this editor, use
- * <mxGraph.invokesStopCellEditing>, <mxGraph.enterStopsCellEditing> and
- * <mxGraph.escapeEnabled>. If <mxGraph.enterStopsCellEditing> is true then
- * ctrl-enter or shift-enter can be used to create a linefeed. The F2 and
- * escape keys can always be used to stop editing. To customize the location
- * of the textbox in the graph, override <getEditorBounds> as follows:
- * 
- * (code)
- * graph.cellEditor.getEditorBounds = function(state)
- * {
- *   var result = mxCellEditor.prototype.getEditorBounds.apply(this, arguments);

- *   }
- *   
- *   return result;
- * };
- * (end)
- * 
- * The textarea uses the mxCellEditor CSS class. You can modify this class in
- * your custom CSS. Note: You should modify the CSS after loading the client
- * in the page.
- *
- * Example:
- * 
- * To only allow numeric input in the in-place editor, use the following code.
- *
- * (code)
- * var text = graph.cellEditor.textarea;
- * 
- * mxEvent.addListener(text, 'keydown', function (evt)

- *   }
- * }); 
- * (end)
- * 
- * Initial values:
- * 
- * To implement an initial value for cells without a label, use the
- * <emptyLabelText> variable.
- * 
- * Resize in Chrome:
- * 
- * Resize of the textarea is disabled by default. If you want to enable

-/**
- * Class: mxCellOverlay
- *
- * Extends <mxEventSource> to implement a graph overlay, represented by an icon
- * and a tooltip. Overlays can handle and fire <click> events and are added to
- * the graph using <mxGraph.addCellOverlay>, and removed using
- * <mxGraph.removeCellOverlay>, or <mxGraph.removeCellOverlays> to remove all overlays.
- * The <mxGraph.getCellOverlays> function returns the array of overlays for a given
- * cell in a graph. If multiple overlays exist for the same cell, then
- * <getBounds> should be overridden in at least one of the overlays.
- * 
- * Overlays appear on top of all cells in a special layer. If this is not
- * desirable, then the image must be rendered as part of the shape or label of
- * the cell instead.
- *
- * Example:
- * 
- * The following adds a new overlays for a given vertex and selects the cell
- * if the overlay is clicked.
- *
- * (code)
- * var overlay = new mxCellOverlay(img, html);
- * graph.addCellOverlay(vertex, overlay);
- * overlay.addListener(mxEvent.CLICK, function(sender, evt)
- * {
- *   var cell = evt.getProperty('cell');
- *   graph.setSelectionCell(cell);
- * });
- * (end)
- * 
- * For cell overlays to be printed use <mxPrintPreview.printOverlays>.
- *
- * Event: mxEvent.CLICK
- *
- * Fires when the user clicks on the overlay. The <code>event</code> property
- * contains the corresponding mouse event and the <code>cell</code> property
- * contains the cell. For touch devices this is fired if the element receives
- * a touchend event.
- * 
- * Constructor: mxCellOverlay
- *
- * Constructs a new overlay using the given image and tooltip.
- * 
- * Parameters:
- * 
- * image - <mxImage> that represents the icon to be displayed.
- * tooltip - Optional string that specifies the tooltip.
- * align - Optional horizontal alignment for the overlay. Possible
- * values are <ALIGN_LEFT>, <ALIGN_CENTER> and <ALIGN_RIGHT>
- * (default).
- * verticalAlign - Vertical alignment for the overlay. Possible
- * values are <ALIGN_TOP>, <ALIGN_MIDDLE> and <ALIGN_BOTTOM>

-	/**
-	 * Class: mxEdgeStyle
-	 * 
-	 * Provides various edge styles to be used as the values for
-	 * <mxConstants.STYLE_EDGE> in a cell style.
-	 *
-	 * Example:
-	 * 
-	 * (code)
-	 * var style = stylesheet.getDefaultEdgeStyle();
-	 * style[mxConstants.STYLE_EDGE] = mxEdgeStyle.ElbowConnector;
-	 * (end)
-	 * 
-	 * Sets the default edge style to <ElbowConnector>.
-	 * 
-	 * Custom edge style:
-	 * 
-	 * To write a custom edge style, a function must be added to the mxEdgeStyle
-	 * object as follows:
-	 * 
-	 * (code)
-	 * mxEdgeStyle.MyStyle = function(state, source, target, points, result)
-	 * {
-	 *   if (source != null && target != null)
-	 *   {
-	 *     var pt = new mxPoint(target.getCenterX(), source.getCenterY());
-	 * 
-	 *     if (mxUtils.contains(source, pt.x, pt.y))
-	 *     {
-	 *       pt.y = source.y + source.height;
-	 *     }
-	 * 
-	 *     result.push(pt);
-	 *   }
-	 * };
-	 * (end)
-	 * 
-	 * In the above example, a right angle is created using a point on the
-	 * horizontal center of the target vertex and the vertical center of the source
-	 * vertex. The code checks if that point intersects the source vertex and makes
-	 * the edge straight if it does. The point is then added into the result array,
-	 * which acts as the return value of the function.
-	 *
-	 * The new edge style should then be registered in the <mxStyleRegistry> as follows:
-	 * (code)
-	 * mxStyleRegistry.putValue('myEdgeStyle', mxEdgeStyle.MyStyle);
-	 * (end)
-	 * 
-	 * The custom edge style above can now be used in a specific edge as follows:
-	 * 
-	 * (code)
-	 * model.setStyle(edge, 'edgeStyle=myEdgeStyle');
-	 * (end)
-	 * 
-	 * Note that the key of the <mxStyleRegistry> entry for the function should
-	 * be used in string values, unless <mxGraphView.allowEval> is true, in
-	 * which case you can also use mxEdgeStyle.MyStyle for the value in the
-	 * cell style above.
-	 * 
-	 * Or it can be used for all edges in the graph as follows:
-	 * 
-	 * (code)
-	 * var style = graph.getStylesheet().getDefaultEdgeStyle();
-	 * style[mxConstants.STYLE_EDGE] = mxEdgeStyle.MyStyle;
-	 * (end)
-	 * 
-	 * Note that the object can be used directly when programmatically setting
-	 * the value, but the key in the <mxStyleRegistry> should be used when
-	 * setting the value via a key, value pair in a cell style.
-	 * 
-	 * Function: EntityRelation
-	 * 
-	 * Implements an entity relation style for edges (as used in database
-	 * schema diagrams). At the time the function is called, the result
-	 * array contains a placeholder (null) for the first absolute point,
-	 * that is, the point where the edge and source terminal are connected.
-	 * The implementation of the style then adds all intermediate waypoints
-	 * except for the last point, that is, the connection point between the
-	 * edge and the target terminal. The first ant the last point in the
-	 * result array are then replaced with mxPoints that take into account
-	 * the terminal's perimeter and next point on the edge.
-	 *
-	 * Parameters:
-	 * 
-	 * state - <mxCellState> that represents the edge to be updated.
-	 * source - <mxCellState> that represents the source terminal.
-	 * target - <mxCellState> that represents the target terminal.
-	 * points - List of relative control points.
-	 * result - Array of <mxPoints> that represent the actual points of the
-	 * edge.

-/**
- * Class: mxGraph
- *
- * Extends <mxEventSource> to implement a graph component for
- * the browser. This is the main class of the package. To activate
- * panning and connections use <setPanning> and <setConnectable>.
- * For rubberband selection you must create a new instance of
- * <mxRubberband>. The following listeners are added to
- * <mouseListeners> by default:
- * 
- * - <tooltipHandler>: <mxTooltipHandler> that displays tooltips
- * - <panningHandler>: <mxPanningHandler> for panning and popup menus
- * - <connectionHandler>: <mxConnectionHandler> for creating connections
- * - <graphHandler>: <mxGraphHandler> for moving and cloning cells
- * 
- * These listeners will be called in the above order if they are enabled.
- *
- * Background Images:
- * 
- * To display a background image, set the image, image width and
- * image height using <setBackgroundImage>. If one of the
- * above values has changed then the <view>'s <mxGraphView.validate>
- * should be invoked.
- * 
- * Cell Images:
- * 
- * To use images in cells, a shape must be specified in the default
- * vertex style (or any named style). Possible shapes are
- * <mxConstants.SHAPE_IMAGE> and <mxConstants.SHAPE_LABEL>.
- * The code to change the shape used in the default vertex style,
- * the following code is used:
- * 
- * (code)
- * var style = graph.getStylesheet().getDefaultVertexStyle();
- * style[mxConstants.STYLE_SHAPE] = mxConstants.SHAPE_IMAGE;
- * (end)
- * 
- * For the default vertex style, the image to be displayed can be
- * specified in a cell's style using the <mxConstants.STYLE_IMAGE>
- * key and the image URL as a value, for example:
- * 
- * (code)
- * image=http://www.example.com/image.gif
- * (end)
- * 
- * For a named style, the the stylename must be the first element
- * of the cell style:
- * 
- * (code)
- * stylename;image=http://www.example.com/image.gif
- * (end)
- * 
- * A cell style can have any number of key=value pairs added, divided
- * by a semicolon as follows:
- * 
- * (code)
- * [stylename;|key=value;]
- * (end)
- *
- * Labels:
- * 
- * The cell labels are defined by <getLabel> which uses <convertValueToString>
- * if <labelsVisible> is true. If a label must be rendered as HTML markup, then
- * <isHtmlLabel> should return true for the respective cell. If all labels
- * contain HTML markup, <htmlLabels> can be set to true. NOTE: Enabling HTML
- * labels carries a possible security risk (see the section on security in
- * the manual).
- * 
- * If wrapping is needed for a label, then <isHtmlLabel> and <isWrapping> must
- * return true for the cell whose label should be wrapped. See <isWrapping> for
- * an example.
- * 
- * If clipping is needed to keep the rendering of a HTML label inside the
- * bounds of its vertex, then <isClipping> should return true for the
- * respective cell.
- * 
- * By default, edge labels are movable and vertex labels are fixed. This can be
- * changed by setting <edgeLabelsMovable> and <vertexLabelsMovable>, or by
- * overriding <isLabelMovable>.
- *
- * In-place Editing:
- * 
- * In-place editing is started with a doubleclick or by typing F2.
- * Programmatically, <edit> is used to check if the cell is editable
- * (<isCellEditable>) and call <startEditingAtCell>, which invokes
- * <mxCellEditor.startEditing>. The editor uses the value returned
- * by <getEditingValue> as the editing value.
- * 
- * After in-place editing, <labelChanged> is called, which invokes
- * <mxGraphModel.setValue>, which in turn calls
- * <mxGraphModel.valueForCellChanged> via <mxValueChange>.
- * 
- * The event that triggers in-place editing is passed through to the
- * <cellEditor>, which may take special actions depending on the type of the
- * event or mouse location, and is also passed to <getEditingValue>. The event
- * is then passed back to the event processing functions which can perform
- * specific actions based on the trigger event.
- * 
- * Tooltips:
- * 
- * Tooltips are implemented by <getTooltip>, which calls <getTooltipForCell>
- * if a cell is under the mousepointer. The default implementation checks if
- * the cell has a getTooltip function and calls it if it exists. Hence, in order
- * to provide custom tooltips, the cell must provide a getTooltip function, or 
- * one of the two above functions must be overridden.
- * 
- * Typically, for custom cell tooltips, the latter function is overridden as
- * follows:
- * 
- * (code)
- * graph.getTooltipForCell = function(cell)
- * {
- *   var label = this.convertValueToString(cell);
- *   return 'Tooltip for '+label;
- * }
- * (end)
- * 
- * When using a config file, the function is overridden in the mxGraph section
- * using the following entry:
- * 
- * (code)
- * <add as="getTooltipForCell"><![CDATA[
- *   function(cell)
- *   {
- *     var label = this.convertValueToString(cell);
- *     return 'Tooltip for '+label;
- *   }
- * ]]></add>
- * (end)
- * 
- * "this" refers to the graph in the implementation, so for example to check if 
- * a cell is an edge, you use this.getModel().isEdge(cell)
- *
- * For replacing the default implementation of <getTooltipForCell> (rather than 
- * replacing the function on a specific instance), the following code should be 
- * used after loading the JavaScript files, but before creating a new mxGraph 
- * instance using <mxGraph>:
- * 
- * (code)
- * mxGraph.prototype.getTooltipForCell = function(cell)
- * {
- *   var label = this.convertValueToString(cell);
- *   return 'Tooltip for '+label;
- * }
- * (end)
- * 
- * Shapes & Styles:
- * 
- * The implementation of new shapes is demonstrated in the examples. We'll assume
- * that we have implemented a custom shape with the name BoxShape which we want
- * to use for drawing vertices. To use this shape, it must first be registered in
- * the cell renderer as follows:
- * 
- * (code)
- * graph.cellRenderer.registerShape('box', BoxShape);
- * (end)
- * 
- * The code registers the BoxShape constructor under the name box in the cell
- * renderer of the graph. The shape can now be referenced using the shape-key in
- * a style definition. (The cell renderer contains a set of additional shapes,
- * namely one for each constant with a SHAPE-prefix in <mxConstants>.)
- *
- * Styles are a collection of key, value pairs and a stylesheet is a collection
- * of named styles. The names are referenced by the cellstyle, which is stored
- * in <mxCell.style> with the following format: [stylename;|key=value;]. The
- * string is resolved to a collection of key, value pairs, where the keys are
- * overridden with the values in the string.
- *
- * When introducing a new shape, the name under which the shape is registered
- * must be used in the stylesheet. There are three ways of doing this:
- * 
- *   - By changing the default style, so that all vertices will use the new
- * 		shape
- *   - By defining a new style, so that only vertices with the respective
- * 		cellstyle will use the new shape
- *   - By using shape=box in the cellstyle's optional list of key, value pairs
- * 		to be overridden
- *
- * In the first case, the code to fetch and modify the default style for
- * vertices is as follows:
- * 
- * (code)
- * var style = graph.getStylesheet().getDefaultVertexStyle();
- * style[mxConstants.STYLE_SHAPE] = 'box';
- * (end)
- * 
- * The code takes the default vertex style, which is used for all vertices that
- * do not have a specific cellstyle, and modifies the value for the shape-key
- * in-place to use the new BoxShape for drawing vertices. This is done by
- * assigning the box value in the second line, which refers to the name of the
- * BoxShape in the cell renderer.
- * 
- * In the second case, a collection of key, value pairs is created and then
- * added to the stylesheet under a new name. In order to distinguish the
- * shapename and the stylename we'll use boxstyle for the stylename:
- * 
- * (code)
- * var style = new Object();
- * style[mxConstants.STYLE_SHAPE] = 'box';
- * style[mxConstants.STYLE_STROKECOLOR] = '#000000';
- * style[mxConstants.STYLE_FONTCOLOR] = '#000000';
- * graph.getStylesheet().putCellStyle('boxstyle', style);
- * (end)
- * 
- * The code adds a new style with the name boxstyle to the stylesheet. To use
- * this style with a cell, it must be referenced from the cellstyle as follows:
- * 
- * (code)
- * var vertex = graph.insertVertex(parent, null, 'Hello, World!', 20, 20, 80, 20,
- * 				'boxstyle');
- * (end)
- * 
- * To summarize, each new shape must be registered in the <mxCellRenderer> with
- * a unique name. That name is then used as the value of the shape-key in a
- * default or custom style. If there are multiple custom shapes, then there
- * should be a separate style for each shape.
- * 
- * Inheriting Styles:
- * 
- * For fill-, stroke-, gradient- and indicatorColors special keywords can be
- * used. The inherit keyword for one of these colors will inherit the color
- * for the same key from the parent cell. The swimlane keyword does the same,
- * but inherits from the nearest swimlane in the ancestor hierarchy. Finally,
- * the indicated keyword will use the color of the indicator as the color for
- * the given key.
- * 
- * Scrollbars:
- * 
- * The <containers> overflow CSS property defines if scrollbars are used to
- * display the graph. For values of 'auto' or 'scroll', the scrollbars will
- * be shown. Note that the <resizeContainer> flag is normally not used
- * together with scrollbars, as it will resize the container to match the
- * size of the graph after each change.
- * 
- * Multiplicities and Validation:
- * 
- * To control the possible connections in mxGraph, <getEdgeValidationError> is
- * used. The default implementation of the function uses <multiplicities>,
- * which is an array of <mxMultiplicity>. Using this class allows to establish
- * simple multiplicities, which are enforced by the graph.
- * 
- * The <mxMultiplicity> uses <mxCell.is> to determine for which terminals it
- * applies. The default implementation of <mxCell.is> works with DOM nodes (XML
- * nodes) and checks if the given type parameter matches the nodeName of the
- * node (case insensitive). Optionally, an attributename and value can be
- * specified which are also checked.
- * 
- * <getEdgeValidationError> is called whenever the connectivity of an edge
- * changes. It returns an empty string or an error message if the edge is
- * invalid or null if the edge is valid. If the returned string is not empty
- * then it is displayed as an error message.
- * 
- * <mxMultiplicity> allows to specify the multiplicity between a terminal and
- * its possible neighbors. For example, if any rectangle may only be connected
- * to, say, a maximum of two circles you can add the following rule to
- * <multiplicities>:
- * 
- * (code)
- * graph.multiplicities.push(new mxMultiplicity(
- *   true, 'rectangle', null, null, 0, 2, ['circle'],
- *   'Only 2 targets allowed',
- *   'Only shape targets allowed'));
- * (end)
- * 
- * This will display the first error message whenever a rectangle is connected
- * to more than two circles and the second error message if a rectangle is
- * connected to anything but a circle.
- * 
- * For certain multiplicities, such as a minimum of 1 connection, which cannot
- * be enforced at cell creation time (unless the cell is created together with
- * the connection), mxGraph offers <validate> which checks all multiplicities
- * for all cells and displays the respective error messages in an overlay icon
- * on the cells.
- * 
- * If a cell is collapsed and contains validation errors, a respective warning
- * icon is attached to the collapsed cell.
- * 
- * Auto-Layout:
- * 
- * For automatic layout, the <getLayout> hook is provided in <mxLayoutManager>.
- * It can be overridden to return a layout algorithm for the children of a
- * given cell.
- * 
- * Unconnected edges:
- * 
- * The default values for all switches are designed to meet the requirements of
- * general diagram drawing applications. A very typical set of settings to
- * avoid edges that are not connected is the following:
- * 
- * (code)
- * graph.setAllowDanglingEdges(false);
- * graph.setDisconnectOnMove(false);
- * (end)
- * 
- * Setting the <cloneInvalidEdges> switch to true is optional. This switch
- * controls if edges are inserted after a copy, paste or clone-drag if they are
- * invalid. For example, edges are invalid if copied or control-dragged without 
- * having selected the corresponding terminals and allowDanglingEdges is
- * false, in which case the edges will not be cloned if the switch is false.
- * 
- * Output:
- * 
- * To produce an XML representation for a diagram, the following code can be
- * used.
- * 
- * (code)
- * var enc = new mxCodec(mxUtils.createXmlDocument());
- * var node = enc.encode(graph.getModel());
- * (end)
- * 
- * This will produce an XML node than can be handled using the DOM API or
- * turned into a string representation using the following code:
- * 
- * (code)
- * var xml = mxUtils.getXml(node);
- * (end)
- * 
- * To obtain a formatted string, mxUtils.getPrettyXml can be used instead.
- * 
- * This string can now be stored in a local persistent storage (for example
- * using Google Gears) or it can be passed to a backend using mxUtils.post as
- * follows. The url variable is the URL of the Java servlet, PHP page or HTTP
- * handler, depending on the server.
- * 
- * (code)
- * var xmlString = encodeURIComponent(mxUtils.getXml(node));
- * mxUtils.post(url, 'xml='+xmlString, function(req)
- * {
- *   // Process server response using req of type mxXmlRequest
- * });
- * (end)
- * 
- * Input:
- * 
- * To load an XML representation of a diagram into an existing graph object
- * mxUtils.load can be used as follows. The url variable is the URL of the Java
- * servlet, PHP page or HTTP handler that produces the XML string.
- * 
- * (code)
- * var xmlDoc = mxUtils.load(url).getXml();
- * var node = xmlDoc.documentElement;
- * var dec = new mxCodec(node.ownerDocument);
- * dec.decode(node, graph.getModel());
- * (end)
- * 
- * For creating a page that loads the client and a diagram using a single
- * request please refer to the deployment examples in the backends.

- * 
- * Constructor: mxGraph
- * 
- * Constructs a new mxGraph in the specified container. Model is an optional
- * mxGraphModel. If no model is provided, a new mxGraphModel instance is 
- * used as the model. The container must have a valid owner document prior 
- * to calling this function in Internet Explorer. RenderHint is a string to
- * affect the display performance and rendering in IE, but not in SVG-based 
- * browsers. The parameter is mapped to <dialect>, which may 
- * be one of <mxConstants.DIALECT_SVG> for SVG-based browsers, 
- * <mxConstants.DIALECT_STRICTHTML> for fastest display mode,
- * <mxConstants.DIALECT_PREFERHTML> for faster display mode,
- * <mxConstants.DIALECT_MIXEDHTML> for fast and <mxConstants.DIALECT_VML> 
- * for exact display mode (slowest). The dialects are defined in mxConstants.
- * The default values are DIALECT_SVG for SVG-based browsers and
- * DIALECT_MIXED for IE.
- *
- * The possible values for the renderingHint parameter are explained below:
- * 
- * fast - The parameter is based on the fact that the display performance is 
- * highly improved in IE if the VML is not contained within a VML group 
- * element. The lack of a group element only slightly affects the display while 
- * panning, but improves the performance by almost a factor of 2, while keeping 
- * the display sufficiently accurate. This also allows to render certain shapes as HTML 
- * if the display accuracy is not affected, which is implemented by 
- * <mxShape.isMixedModeHtml>. This is the default setting and is mapped to
- * DIALECT_MIXEDHTML.
- * faster - Same as fast, but more expensive shapes are avoided. This is 
- * controlled by <mxShape.preferModeHtml>. The default implementation will 
- * avoid gradients and rounded rectangles, but more significant shapes, such 
- * as rhombus, ellipse, actor and cylinder will be rendered accurately. This 
- * setting is mapped to DIALECT_PREFERHTML.
- * fastest - Almost anything will be rendered in Html. This allows for 
- * rectangles, labels and images. This setting is mapped to
- * DIALECT_STRICTHTML.
- * exact - If accurate panning is required and if the diagram is small (up
- * to 100 cells), then this value should be used. In this mode, a group is 
- * created that contains the VML. This allows for accurate panning and is 
- * mapped to DIALECT_VML.
- *
- * Example:
- * 
- * To create a graph inside a DOM node with an id of graph:
- * (code)
- * var container = document.getElementById('graph');
- * var graph = new mxGraph(container);
- * (end)
- *

- * Class: mxMultiplicity
- * 
- * Defines invalid connections along with the error messages that they produce.
- * To add or remove rules on a graph, you must add/remove instances of this

- * 
- * Example:
- * 
- * (code)
- * graph.multiplicities.push(new mxMultiplicity(
- *   true, 'rectangle', null, null, 0, 2, ['circle'],
- *   'Only 2 targets allowed',
- *   'Only circle targets allowed'));

- * 
- * Defines a rule where each rectangle must be connected to no more than 2
- * circles and no other types of targets are allowed.
- * 
- * Constructor: mxMultiplicity
- * 
- * Instantiate class mxMultiplicity in order to describe allowed
- * connections in a graph. Not all constraints can be enforced while
- * editing, some must be checked at validation time. The <countError> and
- * <typeError> are treated as resource keys in <mxResources>.
- * 
- * Parameters:

- * source - Boolean indicating if this rule applies to the source or target
- * terminal.
- * type - Type of the source or target terminal that this rule applies to.
- * See <type> for more information.
- * attr - Optional attribute name to match the source or target terminal.
- * value - Optional attribute value to match the source or target terminal.
- * min - Minimum number of edges for this rule. Default is 1.
- * max - Maximum number of edges for this rule. n means infinite. Default
- * is n.
- * validNeighbors - Array of types of the opposite terminal for which this
- * rule applies.
- * countError - Error to be displayed for invalid number of edges.

-	 * 
-	 * Provides various perimeter functions to be used in a style
-	 * as the value of <mxConstants.STYLE_PERIMETER>. Perimeters for
-	 * rectangle, circle, rhombus and triangle are available.
-	 *
-	 * Example:
-	 * 
-	 * (code)
-	 * <add as="perimeter">mxPerimeter.RightAngleRectanglePerimeter</add>
-	 * (end)
-	 * 
-	 * Or programmatically:
-	 * 
-	 * (code)
-	 * style[mxConstants.STYLE_PERIMETER] = mxPerimeter.RectanglePerimeter;
-	 * (end)
-	 * 
-	 * When adding new perimeter functions, it is recommended to use the 
-	 * mxPerimeter-namespace as follows:
-	 * 
-	 * (code)
-	 * mxPerimeter.CustomPerimeter = function (bounds, vertex, next, orthogonal)
-	 * {
-	 *   var x = 0; // Calculate x-coordinate
-	 *   var y = 0; // Calculate y-coordainte
-	 *   
-	 *   return new mxPoint(x, y);
-	 * }
-	 * (end)
-	 * 
-	 * The new perimeter should then be registered in the <mxStyleRegistry> as follows:
-	 * (code)
-	 * mxStyleRegistry.putValue('customPerimeter', mxPerimeter.CustomPerimeter);
-	 * (end)
-	 * 
-	 * The custom perimeter above can now be used in a specific vertex as follows:
-	 * 
-	 * (code)
-	 * model.setStyle(vertex, 'perimeter=customPerimeter');
-	 * (end)
-	 * 
-	 * Note that the key of the <mxStyleRegistry> entry for the function should
-	 * be used in string values, unless <mxGraphView.allowEval> is true, in
-	 * which case you can also use mxPerimeter.CustomPerimeter for the value in
-	 * the cell style above.
-	 * 
-	 * Or it can be used for all vertices in the graph as follows:
-	 * 
-	 * (code)
-	 * var style = graph.getStylesheet().getDefaultVertexStyle();
-	 * style[mxConstants.STYLE_PERIMETER] = mxPerimeter.CustomPerimeter;
-	 * (end)
-	 * 
-	 * Note that the object can be used directly when programmatically setting
-	 * the value, but the key in the <mxStyleRegistry> should be used when
-	 * setting the value via a key, value pair in a cell style.
-	 * 
-	 * The parameters are explained in <RectanglePerimeter>.
-	 * 
-	 * Function: RectanglePerimeter
-	 * 
-	 * Describes a rectangular perimeter for the given bounds.
-	 *
-	 * Parameters:
-	 * 
-	 * bounds - <mxRectangle> that represents the absolute bounds of the
-	 * vertex.
-	 * vertex - <mxCellState> that represents the vertex.
-	 * next - <mxPoint> that represents the nearest neighbour point on the
-	 * given edge.

-/**
- * Class: mxPrintPreview
- * 
- * Implements printing of a diagram across multiple pages. The following opens
- * a print preview for an existing graph:
- * 
- * (code)
- * var preview = new mxPrintPreview(graph);
- * preview.open();
- * (end)
- * 
- * Use <mxUtils.getScaleForPageCount> as follows in order to print the graph
- * across a given number of pages:
- * 
- * (code)
- * var pageCount = mxUtils.prompt('Enter page count', '1');
- * 
- * if (pageCount != null)
- * {
- *   var scale = mxUtils.getScaleForPageCount(pageCount, graph);
- *   var preview = new mxPrintPreview(graph, scale);
- *   preview.open();
- * }
- * (end)
- * 
- * Headers:
- * 
- * Apart from setting the title argument in the mxPrintPreview constructor you
- * can override <renderPage> as follows to add a header to any page:
- * 
- * (code)
- * var oldRenderPage = mxPrintPreview.prototype.renderPage;
- * mxPrintPreview.prototype.renderPage = function(w, h, dx, dy, scale, pageNumber)
- * {
- *   var div = oldRenderPage.apply(this, arguments);

- *   var header = document.createElement('div');
- *   header.style.position = 'absolute';
- *   header.style.top = '0px';
- *   header.style.width = '100%';
- *   header.style.textAlign = 'right';
- *   mxUtils.write(header, 'Your header here - Page ' + pageNumber + ' / ' + this.pageCount);
- *   div.firstChild.appendChild(header);
- *   
- *   return div;
- * };
- * (end)
- * 
- * Page Format:
- * 
- * For landscape printing, use <mxConstants.PAGE_FORMAT_A4_LANDSCAPE> as
- * the pageFormat in <mxUtils.getScaleForPageCount> and <mxPrintPreview>.
- * Keep in mind that one can not set the defaults for the print dialog
- * of the operating system from JavaScript so the user must manually choose
- * a page format that matches this setting.
- * 
- * You can try passing the following CSS directive to <open> to set the
- * page format in the print dialog to landscape. However, this CSS
- * directive seems to be ignored in most major browsers, including IE.
- * 
- * (code)
- * @page {
- *   size: landscape;
- * }
- * (end)
- * 
- * Note that the print preview behaves differently in IE when used from the
- * filesystem or via HTTP so printing should always be tested via HTTP.
- * 
- * If you are using a DOCTYPE in the source page you can override <getDoctype>
- * and provide the same DOCTYPE for the print preview if required. Here is
- * an example for IE8 standards mode.
- * 
- * (code)
- * var preview = new mxPrintPreview(graph);
- * preview.getDoctype = function()
- * {
- *   return '<!--[if IE]><meta http-equiv="X-UA-Compatible" content="IE=5,IE=8" ><![endif]-->';
- * };
- * preview.open();
- * (end)
- * 
- * Constructor: mxPrintPreview
- *
- * Constructs a new print preview for the given parameters.
- * 
- * Parameters:
- * 
- * graph - <mxGraph> to be previewed.
- * scale - Optional scale of the output. Default is 1 / <mxGraph.pageScale>.
- * border - Border in pixels along each side of every page. Note that the
- * actual print function in the browser will add another border for
- * printing.
- * pageFormat - <mxRectangle> that specifies the page format (in pixels).
- * This should match the page format of the printer. Default uses the
- * <mxGraph.pageFormat> of the given graph.
- * x0 - Optional left offset of the output. Default is 0.
- * y0 - Optional top offset of the output. Default is 0.
- * borderColor - Optional color of the page border. Default is no border.
- * Note that a border is sometimes useful to highlight the printed page
- * border in the print preview of the browser.
- * title - Optional string that is used for the window title. Default
- * is 'Printer-friendly version'.
- * pageSelector - Optional boolean that specifies if the page selector
- * should appear in the window with the print preview. Default is true.

-/**
- * Class: mxStylesheet
- * 
- * Defines the appearance of the cells in a graph. See <putCellStyle> for an
- * example of creating a new cell style. It is recommended to use objects, not
- * arrays for holding cell styles. Existing styles can be cloned using
- * <mxUtils.clone> and turned into a string for debugging using
- * <mxUtils.toString>.
- *
- * Default Styles:
- * 
- * The stylesheet contains two built-in styles, which are used if no style is
- * defined for a cell:
- *
- *   defaultVertex - Default style for vertices
- *   defaultEdge - Default style for edges
- * 
- * Example:
- * 
- * (code)
- * var vertexStyle = stylesheet.getDefaultVertexStyle();
- * vertexStyle[mxConstants.ROUNDED] = true;
- * var edgeStyle = stylesheet.getDefaultEdgeStyle();
- * edgeStyle[mxConstants.STYLE_EDGE] = mxEdgeStyle.EntityRelation;
- * (end)
- * 
- * Modifies the built-in default styles.
- * 
- * To avoid the default style for a cell, add a leading semicolon
- * to the style definition, eg.
- * 
- * (code)
- * ;shadow=1
- * (end)
- * 
- * Removing keys:
- * 
- * For removing a key in a cell style of the form [stylename;|key=value;] the
- * special value none can be used, eg. highlight;fillColor=none
- * 
- * See also the helper methods in mxUtils to modify strings of this format,
- * namely <mxUtils.setStyle>, <mxUtils.indexOfStylename>,
- * <mxUtils.addStylename>, <mxUtils.removeStylename>,
- * <mxUtils.removeAllStylenames> and <mxUtils.setStyleFlag>.
