Ring orientation of polygon are not correctly handled when written through ORG/Shape

[Nicolas Simon]

In shape2ogr.cpp, function SHPReadOGRObject takes care of ring orientation to determine exterior/interior ring of a polygon.

This is not the case in SHPWriteOGRObject. I have OGRPolygon (read from other format) with conterclockwise exterior ring and clockwise interor ring. These king of polygon are not correctly handled. This cause problem when I read again the SHP file trought OGR.

[Even Rouault]

When writing a polygon, SHPWriteOGRObject calls SHPRewindObject whose purpose is to "Reset the winding of polygon objects to adhere to the specification."

Could you provide data and command to reproduce the problem, and describe precisely what the problem is.

I retry with my dataset and found that my dataset was corrupted. This problem should no longer be considered
