var filter:BevelFilter = this.filters[0];
filter.knockout = true;
this.filters = new Array(filter);
}
function createBevelRectangle(name:String):MovieClip {
var w:Number = 100;
var h:Number = 100;
var bgColor:Number = 0x00CC00;
var rect:MovieClip = this.createEmptyMovieClip(name,
this.getNextHighestDepth());
