//可以通过 'path://' 将图标设置为任意的矢量路径。这种方式相比于使用图片的方式，
// 不用担心因为缩放而产生锯齿或模糊，而且可以设置为任意颜色。
// 路径图形会自适应调整为合适的大小。路径的格式参见 SVG PathData(https://www.w3.org/TR/SVG/paths.html#PathData)。
// 可以从 Adobe Illustrator 等工具编辑导出。
// 下面示例中就是使用自定义 path 的 symbol 表现飞机的图形。
// Tip: symbol 的角度会随着轨迹的切线变化，如果使用自定义 path 的 symbol，,
// 需要保证 path 图形的朝向是朝上的，这样在 symbol
// 着轨迹运动的时候可以保证图形始终朝着运动的方向。

2. 注意点
- SVG PathData是啥？ 实际就是＜path＞标签的 d 属性。“M” 开头，“z” 结尾。
- 哪里可以搞到SVG矢量图标？
