setSize.js

function setSize(w, h) {
    if (window.name && w && h) {
        var innerWidth, innerHeight, width = Math.floor(w), height = Math.floor(h);
        innerWidth = (window.innerWidth || document.documentElement.clientWidth);
        innerHeight = (window.innerHeight || document.documentElement.clientHeight);	  
        window.resizeBy(Math.floor(width-innerWidth), Math.floor(height-innerHeight));
        window.moveTo(Math.floor((screen.availWidth/2)-(width/2)), Math.floor((screen.availHeight/2)-(height/2)));
    }
