 Good idea. I could use this, e.g. in
 [source:grass/trunk/vector/v.decimate/main.c?rev=66387#L86 v.decimate]
 where I have now `point_in_region_2d()` and `point_in_region_3d`. I'm
 using `Cell_head` as the region/bbox, but it doesn't contain any info
 whether it is 2D or 3D, if something like `depths=0` (perhaps wrapped in
 `G_is_cell_head_3d()`) would tell if it is 3D, then I could have just
 `point_in_region()`.
