/**
 * Extends {@link mxShape} to implement a double ellipse shape.
 *
 * This shape is registered under {@link mxConstants.SHAPE_DOUBLE_ELLIPSE} in {@link mxCellRenderer}.
 *
 * Use the following override to only fill the inner ellipse in this shape:
 * @example
 * ```javascript
 * mxDoubleEllipse.prototype.paintVertexShape = function(c, x, y, w, h)
 * {
 *   c.ellipse(x, y, w, h);
 *   c.stroke();
 *
 *   var inset = mxUtils.getValue(this.style, mxConstants.STYLE_MARGIN, Math.min(3 + this.strokewidth, Math.min(w / 5, h / 5)));
 *   x += inset;
 *   y += inset;
 *   w -= 2 * inset;
 *   h -= 2 * inset;
 *
 *   if (w > 0 && h > 0)
 *   {
 *     c.ellipse(x, y, w, h);
 *   }
 *
 *   c.fillAndStroke();
 * };
 * ```
