[MapQuery] adding layer changes extent

[Steven M. Ottens]

  Hi all,

I noticed when working on the new mqLayerManager widget that this:
     $("p").click(function() {
         jQuery('#map').data("mapQuery").layers({
             type:'bing',        //create a bing maps layer
             view:'satellite',    //use the bing satellite (aerial) 
layer, instead of bing road (default)
             
key:'ArAGGPJ16xm0RXRbw27PvYc9Tfuj1k1dUr_gfA5j8QBD6yAYMlsAtF6YkVyiiLGn'
             });
         });

changes the extent of the map. This is obviously not desirable. The 
problem here is the layer option zoomToMaxExtent: true. Disabling this 
fixes the problem, however most of the examples will not show a map, 
since they require zoomToMaxExtent set on the layer.

So with some more digging I found that mapquery does this in the Layer 
object:
if (options.zoomToMaxExtent) {
         this.map.olMap.zoomToMaxExtent();
     }

I don't think this should be in the layer object. It does not make sense 
that a layer zooms to the maxextent of the map. it might be that there 
is a function where you can zoom to the maxextent of the layer, but 
that's something different and def. not olMap.zoomToMaxExtent();

I'd like to propose to remove the zoomToMaxExtent option from the Layer 
object and somehow make sure that the map zooms to maxExtent when 
created (unless otherwise specified)

any thoughts?
