OGRSpatialReference::Validate does not return correct error code in Python

[Mateusz Łoskot]

I'm trying to use the Validate method of osgeo.osr.SpatialReference class but I'm experiencing strange problem. Regardless of what WKT is validated - valid or invalid - the Validate() function always returns Zero.

Simple test:

wkt = ... # invalid WKT
srs = osr.SpatialReference()
srs.ImportFromWkt(wkt)
print srs.Validate()   # always returns Zero

To be 100% of that, I patched the C++ implementation of OGRSpatialReference::Validate to always return OGRERR_CORRUPT_DATA (integer value 5), regardless of WKT being validated.

Testing the patched GDAL has confirmed that Zero is returned, always.

Patch used to test and confirm that Python bindings of OGRSpatialReference::Validate function always return Zero, even if original implementation returns different error code
