Geoconcept : error in writing 2.5D/3D export file

[dgrichard]

The 3DOBJECTMONO is duplicated for each 2.5/3D coordinates in the export file instead of being written once for the feature's geometry.

This patch corrects this bug and also handles default precision when writting coordinates : cartesian coordinates are written with 2 decimals (~1cm) and geographical with 9 decimals (~3cm). The driver document is also updated.

The GDAL autotest data should be updated too.

Didier,

gcc warns that hCS at line 5106 of geoconcept.c may be used uninitialized.

Contrarily to pCS which is always set, hCS is only set when in 25D/3D ... I am setting both of them to 0 :
