- * by the SVG standard.
- * Information on fill properties: http://www.w3.org/TR/SVG/painting.html#FillProperties
- * Information on stroke properties: http://www.w3.org/TR/SVG/painting.html#StrokeProperties
- *
- * Symbolizer properties:
- * fill - {Boolean} Set to false if no fill is desired.
- * fillColor - {String} Hex fill color. Default is "#ee9900".
- * fillOpacity - {Number} Fill opacity (0-1). Default is 0.4
- * stroke - {Boolean} Set to false if no stroke is desired.
- * strokeColor - {String} Hex stroke color. Default is "#ee9900".
- * strokeOpacity - {Number} Stroke opacity (0-1). Default is 1.
- * strokeWidth - {Number} Pixel stroke width. Default is 1.
- * strokeLinecap - {String} Stroke cap type. Default is "round". [butt | round | square]
- * strokeDashstyle - {String} Stroke dash style. Default is "solid". [dot | dash | dashdot | longdash | longdashdot | solid]
- * graphic - {Boolean} Set to false if no graphic is desired.
- * pointRadius - {Number} Pixel point radius. Default is 6.
- * pointerEvents - {String} Default is "visiblePainted".
- * cursor - {String} Default is "".
- * externalGraphic - {String} Url to an external graphic that will be used for rendering points.
- * graphicWidth - {Number} Pixel width for sizing an external graphic.
- * graphicHeight - {Number} Pixel height for sizing an external graphic.
- * graphicOpacity - {Number} Opacity (0-1) for an external graphic.
- * graphicXOffset - {Number} Pixel offset along the positive x axis for displacing an external graphic.
- * graphicYOffset - {Number} Pixel offset along the positive y axis for displacing an external graphic.
- * rotation - {Number} For point symbolizers, this is the rotation of a graphic in the clockwise direction about its center point (or any point off center as specified by graphicXOffset and graphicYOffset).
- * graphicZIndex - {Number} The integer z-index value to use in rendering.
- * graphicName - {String} Named graphic to use when rendering points. Supported values include "circle" (default),
- * "square", "star", "x", "cross", "triangle".
- * graphicTitle - {String} Tooltip for an external graphic. Only supported in Firefox and Internet Explorer.
- * backgroundGraphic - {String} Url to a graphic to be used as the background under an externalGraphic.

- * backgroundXOffset - {Number} The x offset (in pixels) for the background graphic.
- * backgroundYOffset - {Number} The y offset (in pixels) for the background graphic.
- * backgroundHeight - {Number} The height of the background graphic. If not provided, the graphicHeight will be used.
- * backgroundWidth - {Number} The width of the background width. If not provided, the graphicWidth will be used.
- * label - {String} The text for an optional label. For browsers that use the canvas renderer, this requires either
- * fillText or mozDrawText to be available.
- * labelAlign - {String} Label alignment. This specifies the insertion point relative to the text. It is a string
- * composed of two characters. The first character is for the horizontal alignment, the second for the vertical
- * alignment. Valid values for horizontal alignment: "l"=left, "c"=center, "r"=right. Valid values for vertical
- * alignment: "t"=top, "m"=middle, "b"=bottom. Example values: "lt", "cm", "rb". The canvas renderer does not
- * support vertical alignment, it will always use "b".
- * labelXOffset - {Number} Pixel offset along the positive x axis for displacing the label.
- * labelYOffset - {Number} Pixel offset along the positive y axis for displacing the label.
- * labelSelect - {Boolean} If set to true, labels will be selectable using SelectFeature or similar controls.
- * Default is false.

-/**
- * 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.

- * Valid options:

- * beforefeatureremoved - Triggered before a feature is removed. Listeners
- * will receive an object with a *feature* property referencing the
- * feature to be removed.
- * featureremoved - Triggerd after a feature is removed. The event
- * object passed to listeners will have a *feature* property with a

- * featuresremoved - Triggered after features are removed. The event
- * object passed to listeners will have a *features* property with a
- * reference to an array of removed features.
- * featureselected - Triggered after a feature is selected. Listeners
- * will receive an object with a *feature* property referencing the
- * selected feature.
- * featureunselected - Triggered after a feature is unselected.
- * Listeners will receive an object with a *feature* property

- * featuremodified - Triggered when a feature has been modified.
- * Listeners will receive an object with a *feature* property referencing
- * the modified feature.
- * afterfeaturemodified - Triggered when a feature is finished being modified.
- * Listeners will receive an object with a *feature* property referencing
- * the modified feature.
- * vertexmodified - Triggered when a vertex within any feature geometry
- * has been modified. Listeners will receive an object with a
- * *feature* property referencing the modified feature, a *vertex*
- * property referencing the vertex modified (always a point geometry),
- * and a *pixel* property referencing the pixel location of the

+/**
+ * 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.MouseToolbar());
+ * > 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);
+ * > }
+ * > });
+ * > map.addControl(control);

+ *
+ * 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

+ *
+ * Parameters:
+ * seg1 - {Object} Object representing a segment with properties x1, y1, x2,
+ * and y2. The start point is represented by x1 and y1. The end point
+ * is represented by x2 and y2. Start and end are ordered so that x1 < x2.

+ * and y2. The start point is represented by x1 and y1. The end point
+ * is represented by x2 and y2. Start and end are ordered so that x1 < x2.
+ * options - {Object} Optional properties for calculating the intersection.
+ *
+ * Valid options:
+ * point - {Boolean} Return the intersection point. If false, the actual
+ * intersection point will not be calculated. If true and the segments
+ * intersect, the intersection point will be returned. If true and
+ * the segments do not intersect, false will be returned. If true and
+ * the segments are coincident, true will be returned.
+ * tolerance - {Number} If a non-null value is provided, if the segments are
+ * within the tolerance distance, this will be considered an intersection.
+ * In addition, if the point option is true and the calculated intersection
+ * is within the tolerance distance of an end point, the endpoint will be
+ * returned instead of the calculated intersection. Further, if the
+ * intersection is within the tolerance of endpoints on both segments, or
+ * if two segment endpoints are within the tolerance distance of eachother
+ * (but no intersection is otherwise calculated), an endpoint on the
+ * first segment provided will be returned.
+ *
+ * Returns:
+ * {Boolean | <OpenLayers.Geometry.Point>} The two segments intersect.
+ * If the point argument is true, the return will be the intersection
+ * point or false if none exists. If point is true and the segments
+ * are coincident, return will be true (and the instersection is equal
