[gdal-dev] [OGR]Add a vertex to a feature

[Mohamed Saâd HESSANE]

Thank's for your suggestion.
I test the OGRLayer::SetFeature() method, but it don't write the file after
that. I think the reason is what say Chaitanya (thank you) about the driver
which don't write until the handle is closed.
I think the best way is to write a CSV/VRT file.
I'm trying now.
