It's a bitfield at the SQL level, which I'll keep.
I'm talking about the liblwgeom level, where you have named 
parameters (is_degree, is_dims), so adding any new option would
require changing the signature anyway.

Hopefully switching to a bitfield at the liblwgeom level would avoid
future needs to further change the interface when new options
needs arise.

I'll provide a patch when I'm done.
