Description
**maptalks's version and what browser you use?**
----
maptalks v1.0.0-rc.25
Browsers: firefox & safari
**Issue description**
----
How do I add Markers that have the correct depth when the map is rotated if the map is tilted. All the examples with markers seem to have the same issue that they have there depth set in the order of being added to the layer, so the last one added is the highest so when you rotate and with a tilt it is always on top, when the expected outcome would be that it would go behind other geo on the map if it is further away.
Is there are way around this?
Thanks
Karl

Research direction
Start by reproducing the linked polygon vertex marker example in Firefox and Safari with the map tilted and rotated. Compare marker ordering with the expected geographic depth behavior; done means markers farther away can render behind nearer map geometry rather than following insertion order.
