Brook,
toXXXX methods can still be used. We just have restricted invalid
conversions, like a LineString to Polygon
A great part of what is valid is tested in
https://github.com/OSGeo/gdal/blob/1ec0b63d8820b2d3f0cfb792e05f3f5fea49892c/autotest/cpp/test_ogr.cpp#L787

I would like to convert a pointer to OGRGeometry into a pointer to the appropriate
derived type based upon the result of wkbFlatten(geometry->getGeometryType()). It
used to be possible to do this with functions like geometry->toLineString().
However, it seems that those are all deleted with the OGR_FORBID_DOWNCAST_TO(name)
macro, although the functions are listed in the API documentation.
How is this conversion supposed to be accomplished now?
Thanks for any pointers.
Cheers,
Brook
