比如说这样绘制的点线面
drawPoint = new SuperMap.Control.DrawFeature(paintLayer, SuperMap.Handler.Point, {multi: true});
drawLine = new SuperMap.Control.DrawFeature(paintLayer, SuperMap.Handler.Path, {multi: true});
drawPolygon = new SuperMap.Control.DrawFeature(vectorLayer, SuperMap.Handler.Polygon);、
如何添加自定义属性(师范程序里的)及修改属性(线宽颜色填充之类的)
