Comment (by robe):
Though this I would consider a bug (at least an error in the error
message). Gives error
ERROR: gbox_overlaps: geometries have mismatched dimensionality
even though they are the same dimension. If we are not going to allow
these functions to be used with higher dimensions we should change this
error message.
