Подскажите как применить градиент к тексту?

Код AS3:
var shape_mask_matrix:Matrix = new Matrix();
shape_mask_matrix.createGradientBox(255, 255, 90, 0, 0);
var shape_mask:Shape = new Shape;
shape_mask.graphics.beginGradientFill(GradientType.LINEAR, [0xd36300, 0xfcff00], [1, 1], [0,255], shape_mask_matrix);
shape_mask.graphics.drawRect(25, 100, 500, 500);
shape_mask.graphics.endFill();
var format_90:TextFormat = new TextFormat;
format_90.font = 'Tahoma';
format_90.size = 90;
format_90.color = 0xEFE284;
format_90.bold = true;
format_90.align = TextFormatAlign.CENTER;
score_text = new TextField;
score_text.defaultTextFormat = format_90;
score_text.width = body.width;
score_text.text = '12500';
score_text.y = text_top.y + 45;
addChild(score_text);
