    1 There is no !SetPoints_2D function in the C API and the comment in the docs next to z param of !SetPoints says that "defaults to NULL for 2D objects".

    55!SetPoints used on a 2D point upgrades it to 3D point. When it is used on a !LineString the behavior depends on stride arguments. If they are zero, the z can be used to force the line string 2D or 3D. If they are not, the line string is always forced to 3D.

    7 I think the coherent behavior should be similar to !SetPoint if z is not null and similar to !SetPoint_2D if z is null. The doc should say "set to NULL for 2D objects, non-null upgrades the geometry to 3D".
