--- Comment #3 from Michael Stahl <mst...@redhat.com> ---
the image in the header has a negative crop, but that is not the problem...

fdo#41068: writerfilter: fix image wrap polygon import
before the commit we get:
debug:11638:1: gcd 4294746427 1350
debug:11638:1: ret 1
now:
debug:14717:1: gcd 220869 1350
debug:14717:1: ret 9
debug:14717:1: nNumerator -220869 mnNumerator 477194047 nGCD 9
debug:14717:1: x 477194047 / 150
debug:14304:1: WrapPolygon [0]: 3181293 0
debug:14304:1: WrapPolygon [1]: 3181293 3661
debug:14304:1: WrapPolygon [2]: 16988 3661
debug:14304:1: WrapPolygon [3]: 16988 0
debug:14304:1: WrapPolygon [4]: 3181293 0
the gcd result of 9 is correct now for -220869 but the subsequent division
is an unsigned one and changes the sign of -220869 to +477194047.
with signed division:
debug:15322:1: gcd 220869 1350
debug:15322:1: ret 9
debug:15322:1: nNumerator -220869 mnNumerator -24541 nGCD 9
debug:15322:1: x -24541 / 150
debug:15322:1: WrapPolygon [0]: -163 0
debug:15322:1: WrapPolygon [1]: -163 3661
debug:15322:1: WrapPolygon [2]: 16988 3661
debug:15322:1: WrapPolygon [3]: 16988 0
debug:15322:1: WrapPolygon [4]: -163 0
