- * 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:

- * > // before Control.MouseDefault gets to see it

- * Class: OpenLayers.Layer.FixedZoomLevels
- * Some Layers will already have established zoom levels (like google

- * 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

- * - *lon* Longitude of the point where a marker is to be placed

- * - *iconOffset* Where the top-left corner of the icon is to be placed
- * relative to the latitude and longitude of the point.

- * inside a popup, which opens when the marker is clicked.
- * - *description* The text of the 'description' is placed below the h2
