GeoPackage development

[mj10777]

Yesterday a spatialite 4.2.0 RC1 was released

• with new functionality for supporting transparently
  • GeoPackage Geometries as if they where Spatialite Geometries
• a transparent SpatialIndex support, is however, missing
  • a functionality needed by geopaparazzi
  • it is probable that this, in time, will also be implemented

I would, therefor, suggest that that portion which will later be needed

• be integrated in now for the branch spatialite_views
  • where the GeoPackage R10 is being done in DaoSpatialite

Full details can be found at the end of this page: https://github.com/geopaparazzi/Spatialite-Tasks-with-Sql-Scripts/wiki/GeoPackage-Index

If you agree, I will do this now - afterwhich a ' good-to-go' can be given

Sounds good to me.

After fixing a typo in the GEOPACKAGE_QUERY_EXTENT_VALID_R10 query

• implemented VirtualGPKG logic
  • AutoGPKGStart is called when needed
  • returns only the spatialite VirtualGPKG table-name instead of geopackage table-name
• implemented gpkgAddSpatialIndex
  • but not used
  • the proper usage will depend on the spatialite 4.2.0 implementation of SpatialIndex
• branch has been updated
  • good-to-go
