Excause me, but I think there is some misunderstanding.
The purpose of FdoGeometry and FdoFgfGeometryFactory APIs
is clear for me.
I'm talking about GeometryFromWkb() and WkbFromGeometry()
functions (which are not a part of the SDK and public API) from:
I'm working on PostGIS provider and I need exactly the same functions.
So, there are two options:
1) copy Geometry.c and Geometry.h to the PostGIS provider directory
2) copy Geometry.c and Geometry.h to some common place for all providers
The second possibility is IMHO the best because of code reuse practice
and to not to keep *the same* code in more than one places.
That was just an idea, and I'd not want to start long discussion about
such a trivial thing :-)
So, I'll just keep my own copy of Geometry.h and Geometry.c files
