rendering problem with riverbank multipolygons and coastline
I've found, that there is a problem when a coastline is part of a
riverbank multipolygone. One possible reason could be that the coastline
has a different direction than the riverbank. The tagging should not be
harmful since natural=coastline and waterway=riverbank do not overwrite
The wiki says "Direction of ways does not matter".
Could someone with osmarender knowledge please have a look at it?
Sample tile is (1180 1565). I've tested it there. Removing the
coastlines from the multipolygone and close the gaps with the riverbank
ways fixes the problem there.
