+/**
+ * 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) {
+ * > alert(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()
+ *
+ *
