This requires GEOS >= 3.3.0 to function properly. On previous
versions, the Z dimension will simply not appear in the wkt.
Disabled OpenLayers editing for 3D geometries (unsupported).
The first try to solve the Python 3 GIS encoding/decoding issue
was too naive. Using decode() on all read strings is bound to fail
as soon as a non-ascii string is concerned.
This patch is a little more clever, leaving ascii decoding when
plain ascii strings are expected, and allowing to specify a custom
encoding in DataSource hierarchy.
* Laid foundations for SpatiaLite support in `GeoQuerySet`, `GeoWhereNode` and the tests.
* Added the `Collect` aggregate for PostGIS (still needs tests).
* Oracle now goes to 11.
* The backend-specific `SpatialRefSys` and `GeometryColumns` models are now attributes of `SpatialBackend`.
* Renamed `GeometryField` attributes to be public that were private (e.g., `_srid` -> `srid` and `_geom` -> `geom_type`).
* Renamed `create_test_db` to `create_test_spatial_db`.
* Removed the legacy classes `GeoMixin` and `GeoQ`.
* Removed evil `\` from spatial backend fields.
* Moved shapefile data from `tests/layermap` to `tests/data`.
Fixed#9794. Refs #9686.
