[fdo-users] MPolygon <-> FDO

[Jonio, Dennis (Aviation)]

Gavin, 
It appears, on the surface at least, that DirectPositionImpl is not
returning the same values that it is being handed. Since in my test
case, that I include below, uses a CircularArc2d object I show that
also. That object hands back what it is passed so I am fairly sure that
that is not the issue.

It looks to me that there are rounding and precision differences. But at
least in this case it looks to me like the MPolygon vertices were all
correctly formed.

DirectPositionImpl? Any additional thoughts?
