"vector_cross_marker"的内容为2D矢量路口大图资源

"vector_cross_attr"的内容为2D矢量路口大图属性

注意事项

1、路口大图图元类型

VectorCrossLayerItem的ItemType为LayerItemVectorCrossType

2、路口大图箭头颜色控制

2.1、矢量路口大图（离线场景）：调整图层的json文件达到颜色配置

2.1.1、"arrow_inner_marker_id"和"arrow_outer_marker_id"决定箭头纹理

2.1.2、“arrow_line_color”和“arrow_border_color”的内容决定箭头颜色。

2.1.3、"arrow_3d_marker_id"为三维场景下的箭头纹理（可与"arrow_inner_marker_id"一致）

2.2、矢量路口大图（在线场景）：由渲染引擎的style样式文件控制，需UED调整样式文件。
