当使用MapboxglLayer读取mapbox的style作为地图时，在倾斜地图后，再旋转地图，已经绘制的线要素会发生无规律偏移

Nobody has claimed this yet.

创建一个地图，style自行替换
var map = new maptalks.Map('map', {
center: [114, 31],
zoom: 10,
baseLayer: new maptalks.MapboxglLayer('tile', {
glOptions: {
'style': 'http://ip/styles/style.json'
}
})
});
var layer = new maptalks.VectorLayer('vector', {forceRenderOnMoving: true}).addTo(map);

再加入一段线，线务必多于三个点

var start = [114, 31],
middle1 = [114, 31.05],
middle2 = [114.05, 31.05],
end = [114.05, 31.08];
var coords = [start, middle1, middle2, end]
var arrow = new maptalks.LineString(
coords,
{
'id': 'arrow',
'arrowStyle': 'classic',
'arrowPlacement': 'vertex-last'
}
) .addTo(layer);

然后倾斜地图45度角或其他倾斜角度，再旋转地图即可见效果
引入的相关库如下：

Use the supplied browser reproduction with MapboxglLayer, a four-point LineString, 45-degree pitch, and map rotation. Inspect the MapboxglLayer integration and vector rendering entry points; done means the already-drawn line remains aligned after pitching and rotating the map.
