tdf#137850 writerfilter compatibilityMode15: ignore behindDoc if wrapped
This patch is based on testing results, since I couldn't find anything
in the documentation that indicated a change between Word 2010
and Word 2013. But the evidence is fairly clear I think.
To quote from MS documentation on relativeHeight:
> This attribute shall only indicate the Z-order with respect to other objects
> in the document which have an identical behindDoc attribute value.
> _All_ objects with a behindDoc value of false shall be displayed
> above elements with a value of true.
But only wrapNone makes mention of being affected by behindDoc,
so apparently MS decided to ignore it for some reason starting
in Word 2013. By simply changing the compatibiltyMode value to
one lower, Word 2013 again starts to honour the behindDoc setting.
