Google maps fitBounds with padding?

After a while I found a solution that works.

if (this.map.getProjection()) {
    var offsetx = 200;
    var offsety = 0;

    var point1 = this.map.getProjection().fromLatLngToPoint(bounds.getSouthWest());
    this.map.fitBounds(bounds);

    var point2 = new google.maps.Point(
        ( (typeof(offsetx) == 'number' ? offsetx : 0) / Math.pow(2, this.map.getZoom()) ) || 0,
        ( (typeof(offsety) == 'number' ? offsety : 0) / Math.pow(2, this.map.getZoom()) ) || 0
    );          

    var newPoint = this.map.getProjection().fromPointToLatLng(new google.maps.Point(
        point1.x - point2.x,
        point1.y + point2.y
    ));

    bounds.extend(newPoint);
    this.map.fitBounds(bounds);
}
