================================================================================= Some geometry extensions do not provide a PyObject as they do not have a Python counterpart as it would serve no purpose to have it. This commit handles this situation making sure to provide the right error to Python or to ignore the extension where appropriate.

// It is intended to have a separate type (not being a Geometry type).
|

// it is intended to have the relevant interface in full for the sketcher extension only
|
|
// It is intended to work on borrowed memory allocation.
