Comment (by David Smith):
Just looking at some of the other C API changes that were made in GDAL at
the time this was implemented. These two items I suggest that we don't
implement.
- void OGRSetNonLinearGeometriesEnabledFlag(int bFlag)
- int OGRGetNonLinearGeometriesEnabledFlag()
The [https://gdal.org/development/rfc/rfc49_curve_geometries.html RFC]
says:
> If they don't want to test the geometry type and explicitly calling the
conversion function, they can call
OGRSetNonLinearGeometriesEnabledFlag(FALSE) (the default value is TRUE,
i.e. non-linear geometries can be returned). In which case, they will be
transformed into their closest linear geometry, by doing linear
approximation, with OGR_G_ForceTo().
Given [https://github.com/django/django/pull/18007 PR#18007] proposes to
implement the geometry curve checking (via `has_curve`) and the linear
conversion method I think that probably gives us enough coverage here.
