com.sencha.gxt.chart.client.draw.Matrix.rotate()
Rotates the matrix using the given angle and arbitrary axis. @param angle the angle used to rotate the matrix @param x the x coordinate of the arbitrary axis @param y the y coordinate of the arbitrary axis

    XElement element = getElement(sprite);
    Style style = element.getStyle();
    Element skew = element.getPropertyJSO("skew").cast();


    if (rotation != null) {
      matrix.rotate(rotation.getDegrees(), rotation.getX(), rotation.getY());

    }
    if (scaling != null) {
      matrix.scale(scaling.getX(), scaling.getY(), scaling.getCenterX(), scaling.getCenterY());
      deltaScaleX *= scaling.getX();
