[gdal-dev] how should SpatialReference::EPSGTreatsAsLatLong work?

[Etienne Tourigny]

The reference for EPSGTreatsAsLatLong  is "This method returns TRUE if
EPSG feels this geographic coordinate system should be treated as
having lat/long coordinate ordering."

However, EPSG 3035 is not a geographic coordinate system, but a
projected one (Lambert Azimuthal Equal Area).
