	)

Callback function to provide a Transformation into the specific chart from the available coordinate representation.

No actual data are transformed by this call, it merely specifies that the given coordinate transformation is possible.

The actual data transformation is performed by the Transformation object that is returned by this call.

It is the responsibility of the Transformator to identify an appropriate source representation within the provided Skeleton and to return the field in this given representation.

The Sourcefield is mandatory, the SourcePositions are optional: Many transformation functions are location-dependent, so the transformation will need the coordinate location of some value, thus the positions are provided when transforming some data field. In some special cases the transformations are location-independent, on which case the SourcePositions field is not needed. Also, if the positions themselves are transformed, then this field is not available yet and will be a nullptr.

Implements Fiber::Transformator.
