-------------------------------+---------------------------
 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.
