-ogr_api.h: (New versions of some functions are needed, use postfix M. If not 3D, Z value is ignored.)
+The current behavior is that calling SetPoint on a point with coordinate dimension 2 upgrades 
+the coordinate dimension 3. To keep 2D points 2D SetPoint_2D must be used. Thus we need
+separate functions for M and ZM geometries. The proposal is to use postfixes M and ZM, i.e.,
+SetPointM, SetPointZM. Similarly for Add and Get and Points.
