[Chameleon] Map refresh slower at bigger scale - Update Map without submit

[Federica De Martin]

Thank you Normand, for the help with UpdateMap widget; I had to change some
part of the functions, because I use Xml Legend but now everything works!

Now I was trying to get the MapSize widget working in jsapi mode. This is
what I've done:
- I replace the folder of the Mapsize widget with the one of chameleon 2.6
- I added in the cwcjsapi.js file the code:
    MAP_SIZE_CHANGED = gnLastEventId ++;
- I added in the UpdateMap.php the code:
    //change map size
    if (isset( $HTTP_FORM_VARS["SET_MAP_WIDTH"]) &&
        isset($HTTP_FORM_VARS["SET_MAP_HEIGHT"]))
    {
        include("widgets/MapSize/MapSize.widget.php");
        $oWidget = new MapSize();
        $oWidget->InitDefaults();
        $oWidget->SetMap($oMapSession);
        $oWidget->SetURL($oHttpFormVars, $HTTP_FORM_VARS);
        $_SESSION["gszCurrentState"] = $oMapSession->saveState();
    }

I thougt that this changes were enough but if I use the map size widget the
map keeps on loading and I have to restart the application;
Do you know if there are other files that has to be changed to make the
MapSize (jsapi mode) work?

Thanks, Federica
