offset_converter should try to produce a closed output path if the input path is closed.
Currently it leaves the path open or produces self intersections and fails for certain offsets.

similar to #1339 (fix isn't working)

herm commented Aug 16, 2012

#1339 is probably unrelated. offset_converter doesn't handle SEG_CLOSE at all.

Other example, line-offset -5.

I think there should be some kind of switch in the code that treats closed ways differently from non-closed ways, if that's not already the case.
