Multipolygons should not union seperate polygons #157

Closed flippmoke closed 8 years ago

flippmoke commented 8 years ago

Currently the code causes all multipolygons to be unioned which could result in some polygons to simply be removed from the resulting dataset.

Origin of issue https://github.com/mapnik/mapnik/issues/3119

The solution will be to change the clipping library to clip each individual polygon in a multiple polygon seperately.
