12988	boost::geometry::difference doesn't operate correctly when many holes are overlapping	flamaros.xavier@…	Barend Gehrels	"I have a multipolygon with an outer that contains many holes that are touching and/or overlapping.

When I make the difference between this multipolygon and an simple polygon that overlap inners the result doesn't contains enough holes. The inners that are overlapped by the polygon I want to substract left from the result.

In my case all inners and the polygon substracted should be unified in one inner in the result.
