* Geometries now allow list-like manipulation, e.g., can add, insert, delete vertexes (or other geometries in collections) like Python lists. Thanks, Aryeh Leib Taurog.
* Added support for GEOS prepared geometries via `prepared` property. Prepared geometries significantly speed up certain operations.
* Added support for GEOS cascaded union as `MultiPolygon.cascaded_union` property.
* Added support for GEOS line merge as `merged` property on `LineString`, and `MultiLineString` geometries. Thanks, Paul Smith.
* No longer use the deprecated C API for serialization to/from WKB and WKT. Now use the GEOS I/O classes, which are now exposed as `WKTReader`, `WKTWriter`, `WKBReader`, and `WKBWriter` (which supports 3D and SRID inclusion)
* Moved each type of geometry to their own module, eliminating the cluttered `geometries.py`.
* Internally, all C API methods are explicitly called from a module rather than a star import.

This removes a long-standing FIXME in the update() handling and allows for
greater flexibility in the values passed in. In particular, it brings updates
into line with saves for django.contrib.gis fields, so fixed#10411.
Thanks to Justin Bronn and Russell Keith-Magee for help with this patch.

* All C API method explictly called from their prototype module, no longer imported via *.
* Applied DRY to C pointer management, classes that do so subclass from `GDALBase`.
* `OGRGeometry`: Added `from_bbox` class method (patch from Christopher Schmidt) and `kml` property.
* `SpatialReference`: Now initialize with `SetFromUserInput` (initialization is now more simple and flexible); removed duplicate methods.
* `Envelope`: Added `expand_to_include` method and now allow same coordinates for lower left and upper right points. Thanks to Paul Smith for tickets and patches.
* `OGRGeomType`: Now treat OGC 'Geometry' type as 'Unknown'.
Fixed#9855, #10368, #10380. Refs #9806.
