On final review I was somewhat concerned about the comment "On input of
geometry, there is no further processing needed as the current code will
save all input loops without checking whether they are outer or inner."

There is a particular winding order expected in properly produced shapefiles.
Does the FDO SHP driver ensure proper winding order for inner and outer
rings when writing shapefiles?
