帮忙大致描述一下这个pr的实现思路，留一个记录

目前存在的问题：
L}8(V46LZHQJ8ZJ$EI_4SMR

需要的功能：实现path的ground剪裁,目前的ContainerExtent不是ground的Extent

VKJ0}3U `}F@RL7 VPEUM62
  • 所以需要个getGroundExtent方法
  • Path 添加groundClip来是否开启ground clip
  • Painter里如果用户开启了groundClip，那么path就用ground Extent来剪裁
  • 3d的墙面绘制(DrawAltitudeSymbolizer) 利用 canvas的clip来实现
  • 3d的连接线(marker),判断线的两个端点是否溢出ground来实现
  • 普通的path，就是利用groundExtent来二次剪裁
