+ * map.addLayer(markers);
+ *
+ * var size = new OpenLayers.Size(21,25);
+ * var offset = new OpenLayers.Pixel(-(size.w/2), -size.h);

+ * markers.addMarker(new OpenLayers.Marker(new OpenLayers.LonLat(0,0),icon));
+ * markers.addMarker(new OpenLayers.Marker(new OpenLayers.LonLat(0,0),icon.clone()));
+ *
+ * (end)
+ *
+ * Note that if you pass an icon into the Marker constructor, it will take
+ * that icon and use it. This means that you should not share icons between
+ * markers -- you use them once, but you should clone() for any additional

-     * (code)
-     * layer.events.register(type, obj, listener);
-     * (end)
-     *
-     * Listeners will be called with a reference to an event object.  The
-     *     properties of this event depends on exactly what happened.
-     *
-     * All event objects have at least the following properties:
-     * object - {Object} A reference to layer.events.object.
-     * element - {DOMElement} A reference to layer.events.element.
-     *
-     * Supported map event types:
-     * loadstart - Triggered when layer loading starts.  When using a Vector 
-     *     layer with a Fixed or BBOX strategy, the event object includes 
-     *     a *filter* property holding the OpenLayers.Filter used when 
-     *     calling read on the protocol.
-     * loadend - Triggered when layer loading ends.  When using a Vector layer
-     *     with a Fixed or BBOX strategy, the event object includes a 
-     *     *response* property holding an OpenLayers.Protocol.Response object.
-     * visibilitychanged - Triggered when the layer's visibility property is
-     *     changed, e.g. by turning the layer on or off in the layer switcher.
-     *     Note that the actual visibility of the layer can also change if it
-     *     gets out of range (see <calculateInRange>). If you also want to catch
-     *     these cases, register for the map's 'changelayer' event instead.
-     * move - Triggered when layer moves (triggered with every mousemove
-     *     during a drag).
-     * moveend - Triggered when layer is done moving, object passed as
-     *     argument has a zoomChanged boolean property which tells that the
-     *     zoom has changed.
-     * added - Triggered after the layer is added to a map.  Listeners will
-     *     receive an object with a *map* property referencing the map and a
-     *     *layer* property referencing the layer.
-     * removed - Triggered after the layer is removed from the map.  Listeners
-     *     will receive an object with a *map* property referencing the map and
-     *     a *layer* property referencing the layer.
+     * APIProperty: popupClass

 /**

- * Class: OpenLayers.Layer.FixedZoomLevels
- *   Some Layers will already have established zoom levels (like google 
- *    or ve). Instead of trying to determine them and populate a resolutions[]
- *    Array with those values, we will hijack the resolution functionality
- *    here.
- * 
- *   When you subclass FixedZoomLevels: 
- * 
- *   The initResolutions() call gets nullified, meaning no resolutions[] array 
- *    is set up. Which would be a big problem getResolution() in Layer, since 
- *    it merely takes map.zoom and indexes into resolutions[]... but....
- * 
- *   The getResolution() call is also overridden. Instead of using the 
- *    resolutions[] array, we simply calculate the current resolution based
- *    on the current extent and the current map size. But how will we be able
- *    to calculate the current extent without knowing the resolution...?
- *  
- *   The getExtent() function is also overridden. Instead of calculating extent
- *    based on the center point and the current resolution, we instead 
- *    calculate the extent by getting the lonlats at the top-left and 
- *    bottom-right by using the getLonLatFromViewPortPx() translation function,
- *    taken from the pixel locations (0,0) and the size of the map. But how 
- *    will we be able to do lonlat-px translation without resolution....?
- * 
- *   The getZoomForResolution() method is overridden. Instead of indexing into
- *    the resolutions[] array, we call OpenLayers.Layer.getExent(), passing in
- *    the desired resolution. With this extent, we then call getZoomForExtent() 
- * 
- * 
- *   Whenever you implement a layer using OpenLayers.Layer.FixedZoomLevels, 
- *    it is your responsibility to provide the following three functions:
- * 
- *   - getLonLatFromViewPortPx
- *   - getViewPortPxFromLonLat
- *   - getZoomForExtent
- * 
- *  ...those three functions should generally be provided by any reasonable 
- *  API that you might be working from.
- *
+ * TODO: deprecate me
+ * Use OpenLayers.Request.proxy instead.

+     * password - {String} Password for relevant authentication scheme.
+     *     Set to null to clear current password.
+     * proxy - {String} Optional proxy.  Defaults to
+     *     <OpenLayers.ProxyHost>.

+     *     string or hash.  Typically, this is only appropriate for <GET>

- * Class: OpenLayers.Control
- * Controls affect the display or behavior of the map. They allow everything
- * from panning and zooming to displaying a scale indicator. Controls by 
- * default are added to the map they are contained within however it is
- * possible to add a control to an external div by passing the div in the
- * options parameter.
- * 
- * Example:
- * The following example shows how to add many of the common controls
- * to a map.
- * 
- * > var map = new OpenLayers.Map('map', { controls: [] });
- * >
- * > map.addControl(new OpenLayers.Control.PanZoomBar());
- * > map.addControl(new OpenLayers.Control.LayerSwitcher({'ascending':false}));
- * > map.addControl(new OpenLayers.Control.Permalink());
- * > map.addControl(new OpenLayers.Control.Permalink('permalink'));
- * > map.addControl(new OpenLayers.Control.MousePosition());
- * > map.addControl(new OpenLayers.Control.OverviewMap());
- * > map.addControl(new OpenLayers.Control.KeyboardDefaults());
- *
- * The next code fragment is a quick example of how to intercept 
- * shift-mouse click to display the extent of the bounding box
- * dragged out by the user.  Usually controls are not created
- * in exactly this manner.  See the source for a more complete 
- * example:
- *
- * > var control = new OpenLayers.Control();
- * > OpenLayers.Util.extend(control, {
- * >     draw: function () {
- * >         // this Handler.Box will intercept the shift-mousedown
- * >         // before Control.MouseDefault gets to see it
- * >         this.box = new OpenLayers.Handler.Box( control, 
- * >             {"done": this.notice},
- * >             {keyMask: OpenLayers.Handler.MOD_SHIFT});
- * >         this.box.activate();
- * >     },
- * >
- * >     notice: function (bounds) {
- * >         OpenLayers.Console.userError(bounds);

- *         will be replaced by the value of the "bar" attribute of the passed
- *         feature.
- * context - {Object} context to take attribute values from
- * feature - {<OpenLayers.Feature.Vector>} optional feature to pass to
- *           <OpenLayers.String.format> for evaluating functions in the
- *           context.
- * property - {String} optional, name of the property for which the literal is
- *            being created for evaluating functions in the context.
- * 
- * Returns:
- * {String} the parsed value. In the example of the value parameter above, the

-     *     properties of this event depends on exactly what happened.
-     *
-     * All event objects have at least the following properties:
-     * object - {Object} A reference to layer.events.object.
-     * element - {DOMElement} A reference to layer.events.element.
-     *
-     * Supported event types:
-     * addtile - Triggered when a tile is added to this layer. Listeners receive
-     *     an object as first argument, which has a tile property that
-     *     references the tile that has been added.
-     * tileloadstart - Triggered when a tile starts loading. Listeners receive
-     *     an object as first argument, which has a tile property that
-     *     references the tile that starts loading.
-     * tileloaded - Triggered when each new tile is
-     *     loaded, as a means of progress update to listeners.
-     *     listeners can access 'numLoadingTiles' if they wish to keep
-     *     track of the loading progress. Listeners are called with an object
-     *     with a 'tile' property as first argument, making the loaded tile
-     *     available to the listener, and an 'aborted' property, which will be
-     *     true when loading was aborted and no tile data is available.
-     * tileerror - Triggered before the tileloaded event (i.e. when the tile is
-     *     still hidden) if a tile failed to load. Listeners receive an object
-     *     as first argument, which has a tile property that references the
-     *     tile that could not be loaded.
-     * retile - Triggered when the layer recreates its tile grid.

- * Class: OpenLayers.Handler
- * Base class to construct a higher-level handler for event sequences.  All
- *     handlers have activate and deactivate methods.  In addition, they have
- *     methods named like browser events.  When a handler is activated, any
- *     additional methods named like a browser event is registered as a
- *     listener for the corresponding event.  When a handler is deactivated,
- *     those same methods are unregistered as event listeners.
+ * Class: OpenLayers.Format.Filter.v1
+ * Superclass for Filter version 1 parsers.

  *
  *

- * Handlers also typically have a callbacks object with keys named like
- *     the abstracted events or event sequences that they are in charge of
- *     handling.  The controls that wrap handlers define the methods that
- *     correspond to these abstract events - so instead of listening for
- *     individual browser events, they only listen for the abstract events
- *     defined by the handler.
- *     
- * Handlers are created by controls, which ultimately have the responsibility
- *     of making changes to the the state of the application.  Handlers
- *     themselves may make temporary changes, but in general are expected to
- *     return the application in the same state that they found it.

+ * options parameter.
+ * 
+ * Example:
+ * The following example shows how to add many of the common controls
+ * to a map.
+ * 
+ * > var map = new OpenLayers.Map('map', { controls: [] });
+ * >
+ * > map.addControl(new OpenLayers.Control.PanZoomBar());

+ * dragged out by the user.  Usually controls are not created
+ * in exactly this manner.  See the source for a more complete

+ *
+ * > var control = new OpenLayers.Control();
+ * > OpenLayers.Util.extend(control, {

+ *     additional methods named like a browser event is registered as a

+ *     handling.  The controls that wrap handlers define the methods that
+ *     correspond to these abstract events - so instead of listening for
+ *     individual browser events, they only listen for the abstract events
+ *     defined by the handler.
+ *     
+ * Handlers are created by controls, which ultimately have the responsibility
+ *     of making changes to the the state of the application.  Handlers
+ *     themselves may make temporary changes, but in general are expected to

+ *     care to differentiate between the types of events that correspond with
+ *     the end of a drag sequence.  If no drag actually occurs (no mouse move)
+ *     the 'down' and 'up' callbacks will be called, but not the 'done'

- *     a drag sequence begins, when a drag is happening, and when it has
- *     finished.
- *
- * Controls that use the drag handler typically construct it with callbacks
- *     for 'down', 'move', and 'done'.  Callbacks for these keys are called
- *     when the drag begins, with each move, and when the drag is done.  In
- *     addition, controls can have callbacks keyed to 'up' and 'out' if they
- *     care to differentiate between the types of events that correspond with
- *     the end of a drag sequence.  If no drag actually occurs (no mouse move)
- *     the 'down' and 'up' callbacks will be called, but not the 'done'
- *     callback.
- *
- * Create a new drag handler with the <OpenLayers.Handler.Drag> constructor.

- * Class: OpenLayers.Popup
- * A popup is a small div that can opened and closed on the map.

- * layer and are added the the map using the <OpenLayers.Map.addPopup>
- * method.
+ * Class: OpenLayers.Renderer.VML
+ * Render vector features in browsers with VML capability.  Construct a new
+ * VML renderer with the <OpenLayers.Renderer.VML> constructor.
+ * 
+ * Note that for all calculations in this class, we use (num | 0) to truncate a 
+ * float value to an integer. This is done because it seems that VML doesn't 
+ * support float values.

  *
  *

- * Example:
- * (code)
- * popup = new OpenLayers.Popup("chicken", 
- *                    new OpenLayers.LonLat(5,40),
- *                    new OpenLayers.Size(200,200),

-     * Do this in a separate function so that subclasses can 
-     *   choose to override it if they wish to deal differently
-     *   with mouse events
-     * 
-     *   Note in the following handler functions that some special
-     *    care is needed to deal correctly with mousing and popups. 
-     *   
-     *   Because the user might select the zoom-rectangle option and
-     *    then drag it over a popup, we need a safe way to allow the
-     *    mousemove and mouseup events to pass through the popup when
-     *    they are initiated from outside. The same procedure is needed for
-     *    touchmove and touchend events.
-     * 
-     *   Otherwise, we want to essentially kill the event propagation
-     *    for all other events, though we have to do so carefully, 
-     *    without disabling basic html functionality, like clicking on 
-     *    hyperlinks or drag-selecting text.
+     * Register a listener for a particular event with the following syntax:
+     * (code)
+     * tile.events.register(type, obj, listener);
+     * (end)
+     *
+     * Supported event types:
+     * beforedraw - Triggered before the tile is drawn. Used to defer
+     *     drawing to an animation queue. To defer drawing, listeners need

-     * filter - {Function} A function which will be called for every key and
-     *     value at every level of the final result. Each value will be
-     *     replaced by the result of the filter function. This can be used to
-     *     reform generic objects into instances of classes, or to transform
-     *     date strings into Date objects.
+     * Note:

      *
      *

-     * Returns: 
-     * {Object} The return depends on the value of the type argument. If type
-     *     is "FeatureCollection" (the default), the return will be an array
-     *     of <OpenLayers.Feature.Vector>. If type is "Geometry", the input json
-     *     must represent a single geometry, and the return will be an
-     *     <OpenLayers.Geometry>.  If type is "Feature", the input json must
-     *     represent a single feature, and the return will be an
-     *     <OpenLayers.Feature.Vector>.
+     * The displaying of tiles is not animated by default for single tile
+     *     layers - OpenLayers' default theme (style.css) includes this:
+     * (code)
+     * .olLayerGrid .olTileImage {
+     *     -webkit-transition: opacity 0.2s linear;
+     *     -moz-transition: opacity 0.2s linear;
+     *     -o-transition: opacity 0.2s linear;
+     *     transition: opacity 0.2s linear;
+     *  }
+     * (end)
+     * To animate tile displaying for any grid layer the following
+     *     CSS rule can be used:
+     * (code)
+     * .olTileImage {
+     *     -webkit-transition: opacity 0.2s linear;
+     *     -moz-transition: opacity 0.2s linear;
+     *     -o-transition: opacity 0.2s linear;
+     *     transition: opacity 0.2s linear;
+     * }
+     * (end)
+     * In that case, to avoid flash effects, <removeBackBufferDelay>
+     *     should not be zero.

      *

-     * Allowed config properties:
-     * method - {String} One of GET, POST, PUT, DELETE, HEAD, or
-     *     OPTIONS.  Default is GET.
-     * url - {String} URL for the request.
-     * async - {Boolean} Open an asynchronous request.  Default is true.

-     *     to null to clear current user.
-     * password - {String} Password for relevant authentication scheme.
-     *     Set to null to clear current password.
-     * proxy - {String} Optional proxy.  Defaults to
-     *     <OpenLayers.ProxyHost>.
-     * params - {Object} Any key:value pairs to be appended to the

-     *     data.  For <POST> and <PUT> requests, the content type defaults to
-     *     "application-xml".  If your data is a different content type, or
-     *     if you are using a different HTTP method, set the "Content-Type"
-     *     header to match your data type.
-     * callback - {Function} Function to call when request is done.
-     *     To determine if the request failed, check request.status (200
-     *     indicates success).
-     * success - {Function} Optional function to call if request status is in
-     *     the 200s.  This will be called in addition to callback above and
-     *     would typically only be used as an alternative.
-     * failure - {Function} Optional function to call if request status is not
-     *     in the 200s.  This will be called in addition to callback above and
-     *     would typically only be used as an alternative.
-     * scope - {Object} If callback is a public method on some object,
-     *     set the scope to that object.
+     * Required configuration properties:
+     * key - {String} Bing Maps API key for your application. Get one at

- * Class: OpenLayers.Rule
- * This class represents an SLD Rule, as being used for rule-based SLD styling.
+ * Class: OpenLayers.Layer.FixedZoomLevels
+ *   Some Layers will already have established zoom levels (like google 
+ *    or ve). Instead of trying to determine them and populate a resolutions[]
+ *    Array with those values, we will hijack the resolution functionality
+ *    here.
+ * 
+ *   When you subclass FixedZoomLevels: 
+ * 
+ *   The initResolutions() call gets nullified, meaning no resolutions[] array 
+ *    is set up. Which would be a big problem getResolution() in Layer, since 
+ *    it merely takes map.zoom and indexes into resolutions[]... but....
+ * 
+ *   The getResolution() call is also overridden. Instead of using the 
+ *    resolutions[] array, we simply calculate the current resolution based
+ *    on the current extent and the current map size. But how will we be able
+ *    to calculate the current extent without knowing the resolution...?
+ *  
+ *   The getExtent() function is also overridden. Instead of calculating extent
+ *    based on the center point and the current resolution, we instead 
+ *    calculate the extent by getting the lonlats at the top-left and 
+ *    bottom-right by using the getLonLatFromViewPortPx() translation function,
+ *    taken from the pixel locations (0,0) and the size of the map. But how 
+ *    will we be able to do lonlat-px translation without resolution....?
+ * 
+ *   The getZoomForResolution() method is overridden. Instead of indexing into
+ *    the resolutions[] array, we call OpenLayers.Layer.getExent(), passing in
+ *    the desired resolution. With this extent, we then call getZoomForExtent() 
+ * 
+ * 
+ *   Whenever you implement a layer using OpenLayers.Layer.FixedZoomLevels, 
+ *    it is your responsibility to provide the following three functions:
+ * 
+ *   - getLonLatFromViewPortPx
+ *   - getViewPortPxFromLonLat
+ *   - getZoomForExtent
+ * 
+ *  ...those three functions should generally be provided by any reasonable 
+ *  API that you might be working from.

- * Controls that use the pinch handler typically construct it with callbacks

-     * If a point is to be styled with externalGraphic and rotation, VML fills
-     * cannot be used to display the graphic, because rotation of graphic
-     * fills is not supported by the VML implementation of Internet Explorer.
-     * This method creates a olv:imagedata element inside the VML node,

-     * Finally, OpenLayers methods are used to determine the correct
