Joaquim,

I'd be willing to implement such a feature if there is significant
interest in it, but I'd rather see it held as one of several things
to do on a second pass through the driver since it is just an optimization.

Currently the driver uses the same formatting function used for forming
WKT geometries, which has some logic manage precision.

Best regards,
