测试浏览器是否支持`webgl`.

### Parameters
- `options` **`Object`?**
    - `options.failIfMajorPerformanceCaveat` **`boolean`**如果`true`，如果`true`，`false`如果性能比预期的差很多（例如，将使用软件 WebGL 渲染器），该函数将返回。（任选，默认`false`）

### Examples
```
// Show an alert if the browser does not support webgl
if (!vjmap.supported()) {
  alert('Your browser does not support `webgl`');
}
```

返回 **`boolean`**
